<n_ NETWORKS Information GENERAL INFORMATION ON USING HIGH MEMORY FOR NETWORKS ===================================================== PREFACE ------- The ALLEMM4 Software includes programs which allow you to relocate DOS resources, like Files, Buffers, Lastdrive, and Device Drivers, above 640K into high memory. In addition, any TSRs (Terminate-and-Stay- Resident or memory resident programs) can also be relocated into high memory (with ALLOAD). Networks are TSR shells which load on top of DOS and end up using your conventional memory. This file will help you optimize the use of high memory for various networks, providing you with more DOS memory for your applications. Since this is a general outline, specific cases will not be discussed. However, the information which follows will apply to any network you run. MAXIMIZING HIGH MEMORY ---------------------- To optimize the use of high memory for your network you will need to provide as much contiguous space between 640K and 1024K as possible. In the MEMORY/First Meg screen under ALLMENU you will get a graphical representation of the physical First Megabyte of memory in your computer. The dotted (.) areas indicate free spaces which can be used as high memory. These areas are set as high memory when you include the RAM option with the ALLEMM4 statement in your CONFIG.SYS file. DEVICE=ALLEMM4.SYS RAM <plus other options> However, every network requires a hardware adapter through which you communicate with the server and other users. For the purposes of this discussion there are two types of network adapters: 1. The hardware adapter is accessed through a software controlled I/O port and does not use any physical addresses in the system. 2. The hardware adapter is accessed through a RAM buffer, or includes some option ROM, or both, which occupies some physical addresses between 640K and 1024K. In the first case, the ALLEMM4 driver statement in your CONFIG.SYS file need only include the RAM option as follows: DEVICE=ALLEMM4.SYS RAM If your network adapter is of the second type, then you must use the X option (in addition to the RAM option) to exclude the range of addresses that the adapter occupies. DEVICE=ALLEMM4.SYS RAM X=sp00-spFF * sp00 and spFF specify the start and end addresses of the range(s) to be excluded for the network adapter; the "s" represents the Segment and "p" is the Page of the address in hexadecimal. In some cases, the network adapter RAM and/or ROM locations can be relocated to different addresses. The Harware section (in ALLMENU) provides somes details on how to relocate various network adapters. Once you have installed the ALLEMM4 driver with the RAM option you will be able to see the high memory areas in your system. Run EXAMEM under the ALLEMM4 selection in ALLMENU. The "T"s represent the high memory in your system; each "T" equals 4K of memory. The more "T"s there are the more high memory you have. If you have used the EXCLUDE option with ALLEMM4, then the excluded ranges will be marked "X". The excluded ranges may fragment your high memory. Your objective is to have as many contiguous "T"s as possible, so you may need to go back and relocate the RAM/ROM addresses of the network adapter. If the your network adapterd has any ROM, RAM or both which occupies addresses in reserved memory space (between 640K and 1024K) then: If possible try to set your network RAM/ROM at the beginning or end of a block of "T"s (minimizing the fragmentation) or set the RAM/ROM addresses to the smallest block of "T"s (in cases where there is more than one high memory block). INSTALLING YOUR NETWORK ----------------------- Now that you have found the best possible position to place your network adapter RAM/ROM, and enabled high memory (RAM with ALLEMM4 in CONFIG.SYS) you should rerun EXAMEM to have a look at the free memory above 640K. You can now use the DEVICE and ALLOAD programs to load the various network files (plus other TSRs) above 640K into the free high memory. *** Before you install these commands in your AUTOEXEC.BAT file, run them from the command line, test your network, and view your configuration under EXAMEM to make sure every is working properly. Note: You can gain an additional 64K of high memory by eliminating the EMS Pageframe. If the applications you plan to run do not require expanded memory you can add the FRAME=NONE option to ALLEMM4.SYS in your CONFIG.SYS file. DEVICE=ALLEMM4.SYS RAM FR=NONE <+ X'ed areas) At this point your system should be operational. <n_ Hardware Arcnet CONFIGURING ARCNET ADPATERS FOR HIGH MEMORY =========================================== ARCNET adapters have on-board memory which is used as a RAM buffer by the network. All accesses are made through this fixed "area" located in reserved memory space between 640K and 1024K. The size of this area depends on the ARCNET card model and manufacturer. Most ARCNET cards have a STANDARD operating mode for workstations that claims 64K of high memory space beginning at D0000h. This operating mode, sometimes referred to as COMPATIBLE mode, is the native mode for ARCNET adapters. If your ARCNET adapter claims 64K at D0000h then the ALLEMM4.SYS statment in your CONFIG.SYS file should appear be as follows: DEVICE=ALLEMM4.SYS RAM X=D000-DFFF Some ARCNET manufacturers have produced adapters which only require 16K of memory space beginning at CC000h or D0000h. These cards run in what is commonly called ENHANCED mode. If your ARCNET adapter requires only 16K then ALLEMM4 should read: DEVICE=ALLEMM4.SYS RAM X=CC00 or DEVICE=ALLEMM4.SYS RAM X=D000 <n_ Hardware Proteon CONFIGURING PROTEON PRONET-10 FOR HIGH MEMORY ============================================= Pronet-10 cards do not claim any memory UNLESS there is an automatic Boot PROM on the board. If there is a Boot PROM, then 16K of memory will be used at any location ranging from C0000h to FC000h in multiples of 16K (i.e. C0000, C4000, C8000, etc.). If your PRONET-10 adapter includes the Boot PROM then set ALLEMM4 to exclude the appropriate range. DEVICE=ALLEMM4.SYS RAM X=sp00 * where "s" represents the Segment and "p" is the Page of the address in hexadecimal. <n_ Hardware IBM Tkn Rng CONFIGURING TOKEN-RING ADAPTERS FOR HIGH MEMORY =============================================== Token-Ring Adapters include both a RAM buffer and an option ROM which use physical addresses in high memory. The size of the RAM and ROM will vary depending on whether you have the PRIMARY adapter, ADAPTER II or 16Mips card. a) PRIMARY ADAPTER (4Mips) b) ADAPTER II (4Mips) c) 16Mips Adapter The PRIMARY adapter is a 4Mips card that has an 8K RAM and 8K ROM. The ADAPTER II (which is also 4Mips) has a 16K RAM buffer and 16K of ROM. In the 16Mips card the RAM buffer size can be set to 8K, 16K, 32K or 64K. However, despite the various RAM buffer sizes available, the 16K buffer yeilds the best performace. In the 16Mips card the ROM is also 16K in length. To change the ROM and RAM addresses of the Token- Ring adapter on IBM PS/2 systems with a Micro Channel (MCA) you must make changes to the IBM PS/2 Reference Disk text file for your adapter. If the system is NOT a micro channel (ie. ISA - Industry Standard Architecture) the ROM address of the Token-Ring adapter has to be changed using switches 1 through 6 on the switch block, while the RAM address is changed by adding an option to the DXMC0MOD.SYS device driver indicating the desired RAM address location. ISA INSTALLATION ---------------- If you have an EGA or VGA color system the best address range to select for the RAM and ROM is between the Text and Graphics buffers of the video adapter -- from B0000h to B7FFFh. In monochrome or CGA systems, use C0000h as the base address for the adapter settings. The tables below indicate the optimal setting for each of the three types of Token-Ring Adapters available in ISA systems with different video cards. PRIMARY ADAPTER RAM Address ROM Address EGA/VGA color B4000h B6000h Mono/CGA C0000h C2000h DEVICE=ALLEMM4.SYS RAM X=B400 for EGA/VGA color DEVICE=ALLEMM4.SYS RAM X=C000 for Mono/CGA ADAPTER II RAM Address ROM Address EGA/VGA color B0000h B4000h Mono/CGA C0000h C4000h DEVICE=ALLEMM4.SYS RAM X=B000-B7FF for EGA/VGA color DEVICE=ALLEMM4.SYS RAM X=C000-C7FF for Mono/CGA 16MIPS ADAPTER RAM Address ROM Address EGA/VGA color B0000h (16K) B4000h Mono/CGA C0000h (16K) C4000h DEVICE=ALLEMM4.SYS RAM X=B000-B7FF for EGA/VGA color DEVICE=ALLEMM4.SYS RAM X=C000-C7FF for Mono/CGA To set the base ROM address on Switch Block 1 follow the table below: Base Address Bits 19 - 14 Switches 1 - 6 A8000h 101011 N F N F N N AA000h 101010 N F N F N F AC000h 101001 N F N F F N B0000h 100111 N F F N N N B2000h 100110 N F F N N F B4000h 100101 N F F N F N B8000h 100011 N F F F N N BC000h 100001 N F F F F N C0000h 011111 F N N N N N C2000h 011110 F N N N N F C4000h 011101 F N N N F N C8000h 011011 F N N F N N CC000h 011001 F N N F F N D0000h 010111 F N F N N N D4000h 010101 F N F N F N DC000h 010001 F N F F F N Note: F=OFF and N=ON Set the RAM starting address with DXMC0MOD.SYS as follows: DEVICE=DXMC0MOD.SYS ,sp00 * where "s" represents the Segment and "p" is the Page of the address in hexadecimal. For the examples given above in EGA/VGA color systems: PRIMARY ADAPTER: DXMC0MOD.SYS ,B400 ADAPTER II: DXMC0MOD.SYS ,B000 16MIPS ADAPTER: DXMC0MOD.SYS ,B000 MCA INSTALLATION ---------------- In a Micro Channel there is only a 4Mips Adapter and 16Mips Adpater available. If you have the 16Mips Adpater, then the 16K RAM buffer size should be selected as it is the most optimal setting. If you have an EGA or VGA color system the best address range to select for the RAM and ROM is between the Text and Graphics buffers of the video adapter -- from B0000h to B7FFFh. In monochrome or CGA systems, use C0000h as the base address for the adapter settings. Unlike ISA systems, adapters in a MCA system are set through software via the Reference Disk. The available settings can be changed by modifying the appropriate reference file with a text or ASCII editor. If you have the 4Mips Token-Ring Adapter then you should edit the file: @E000.ADF If you have the 16Mips Token-Ring Adapter then you should edit the file: @E001.ADF Below is an example of what you will see in both the @E000.ADF and @E001.ADF file for ROM settings: CHOICE " "CC000-CDFFF" " POS[2] = 1100110Xb MEM 0CC000h-0CDFFFh If you have VGA color change the above setting to read: CHOICE " "B0000-B3FFF" " POS[2] = 1011000Xb MEM 0B0000h-0B3FFFh <OMIT THIS LINE ON 386s> If you have VGA Mono change the above setting to read: CHOICE " "C0000-C3FFF" " POS[2] = 1100000Xb MEM 0B0000h-0B3FFFh <OMIT THIS LINE ON 386s> Below is an example of what you will see in the .ADF file for RAM settings: @E000.ADF: CHOICE " "DC000-DFFFF" " POS[0] = 1101110Xb MEM 0DC000h-0DFFFFh If you have VGA color change the above setting to read: CHOICE " "B4000-B7FFF" " POS[0] = 1011010Xb MEM 0B4000h-0B7FFFh <OMIT THIS LINE ON 386s> If you have VGA Mono change the above setting to read: CHOICE " "C4000-C7FFF" " POS[2] = 1100010Xb MEM 0C4000h-0C7FFFh <OMIT THIS LINE ON 386s> @E001.ADF: CHOICE " "16KB/DC000-DFFFF" " POS[0] = 1101110Xb POS[1] = XXXX01XXb MEM 0DC000h-0DFFFFh In a system with VGA color change the above setting to read: CHOICE " "16KB/B4000-B7FFF" " POS[0] = 1011010Xb POS[1] = XXXX01XXb MEM 0B4000h-0B7FFFh <OMIT THIS LINE ON 386s> If the system has VGA Mono then the lines should read: CHOICE " "16KB/C4000-C7FFF" " POS[0] = 1100010Xb POS[1] = XXXX01XXb MEM 0C4000h-0C7FFFh <OMIT THIS LINE ON 386s> Once you have saved the appropriate changes to the .ADF file which applies to your Token-Ring adapter, you must reboot your computer and rerun the SETUP with the Reference Disk. Run "Set Configuration" and select the new addresses for the Token-Ring adapter. The ALLEMM4 statement line in your CONFIG.SYS file should reflect the new addresses: DEVICE=ALLEMM4.SYS RAM X=B000-B7FF <for color> DEVICE=ALLEMM4.SYS RAM X=C000-C7FF <for mono> Now that you have set your Token-Ring Adapter you can proceed with loading the device driver into high memory. LOADING THE TOKEN-RING DRIVERS ------------------------------ If you are using Token-Ring device drivers then all of them can be loaded into high memory if the PAL on your Token-Ring has had its serial number burnt in to it. If you have to supply the serial number, then only the DXMT0MOD.SYS driver can be loaded into high memory. Your Token-Ring drivers should always be loaded in the following order: DXMA0MOD.SYS should be loaded first DXMC0MOD.SYS should be loaded second, and DXMT0MOD.SYS (optional) should be loaded third. IMPORTANT: If you are using the IBM 3270 Connection Adapter for 3270 emulation, then it is critical where it and the IBM Token-Ring Adapter sit in the BUS. The 3270 Connection Adapter should be in Slot 1 (nearest the outside casing) and the IBM Token- Ring Adapter should be in Slot 2 next to it. <n_ Hardware Other COMMON ADAPTER CARDS WITH THEIR ROM OR RAM SETTINGS =================================================== The following is a list of some common network and emulation cards with the ROM and RAM addresses they can be set for. Please refer to the documentation for each if you need more information on how to change the addresses for your operating environment. 3270 CONNECTION A: CE00-CFFF FIXED ADDRESS CANNOT BE MOVED 3270 CONNECTION B: C000-C1FF, C200-C3FF, C400-C5FF, C600-C7FF C800-C9FF, CA00-CBFF, CC00-CDFF, CE00-CFFF D000-D1FF, D200-D3FF, D400-D5FF, D600-D7FF D800-D9FF, DA00-DBFF, DC00-DDFF, DE00-DFFF 8514/A ADAPTER: C680-C7FF, CA00-CA80 ESDI: C000-C3FF, C400-C7FF, C800-CBFF, CC00-CFFF D000-D3FF, D400-D7FF, D800-DBFF, DC00-DFFF PC NETWORK ADAPTER II/A PRIMARY: C800-CFFF, D000-D7FF, D800-DFFF ALTERNATE: CE00-CFFF, D600-D7FF, DE00-DFFF TOKEN-RING ADAPTER: refer to Token Ring Section. UNGERMAN BASS PLC: Can be set using Jumpers A15, A16, A17, A18 on a 32KB boundary starting at 8000 to FFFF. *** The best possible setting for the PLC when using high memory is as follows: MEMORY JUMPER SETTINGS ADDRESSES A15 A16 A17 A18 ------------------------- --- --- --- --- B000-B7FF (VGA/EGA color) OFF ON ON OFF C000-C7FF (Mono/CGA) OFF OFF OFF ON After the JUMPER setting is completed you may have to run "PC GEN" and change the "TRANSMIT BUFFERS" parameter to inform the network software of the new hardware memory addresses. WESTERN DIGITAL VIANET, ETHERCARD PLUS and STARCARD PLUS: These cards have 8K of RAM in the reserved area. To change this address in the VIANET.BAT or ON.BAT file, add the new address location by using the "/M:sp000" on the 8003DRVR command, where "s" is Segment and "p" the Page of the new RAM location in hexadecimal. For example, for address "B000- B1FF", use 8003DRVR /M:B0000. Remember to EXCLUDE this address from ALLEMM4.SYS in your CONFIG.SYS file: DEVICE=ALLEMM4.SYS X=B000-B1FF. ETHERCARD PLUS ADVANCED (16BIT CARD) Uses ROM and RAM addresses on a 16K boundary. It can be set for: C000-C3FF, C400-C7FF, C800-CBFF, CC00-CFFF D000-D3FF, D400-D7FF, D800-DBFF, DC00-DFFF Try to set the address for the lowest possible location. <n_ Software Banyan LOADING BANYAN VINES INTO HIGH MEMORY ===================================== If your network adapter has any ROM, RAM or both which occupies addresses in reserved memory space (between 640K and 1024K) then: a) Set the network ROM/RAM to the beginning or end of a high memory block to minimize possible fragmentation or set the ROM/RAM addresses to the smallest high memory block (in cases where there is more than one high memory block). b) Exclude the ROM/RAM address range(s) you have selected for the network adapter with ALLEMM4.SYS and include the RAM option. DEVICE=ALLEMM4.SYS RAM X=<network adapter addr.> At the DOS prompt (or AUTOEXEC.BAT) use the Files, Buffers, Lastdrive and Device programs supplied to load these DOS resources into high memory. If your network adapter has any ROM, RAM or both which occupies addresses in reserved memory space (between 640K and 1024K) then: VINES 3.X --------- The BAN.COM program normally loads the entire network at once, it consists of three (3) parts: a) BAN.COM (Interrrupt Dispatcher) b) The network board driver (listed below) c) EPCBFS.COM (DOS Redirector) Each of the various network parts listed above may be loaded individually by running the BAN.COM program with the /NC (ie. No Controller) option. BAN /NC The /NC option will load only BAN.COM (approx.1K). You can then proceed to use the ALLOAD program to load the other parts of VINES above 640K. ALLOAD <filename of controller> ie. for Etherlink: ALLOAD ETHERBAN and finally ALLOAD EPCBFS MEMORY REQUIREMENTS FOR VINES 3.01 ---------------------------------- Description File Name Size Addr. --------------------------------------------------- *****Base Software***** Interrupt Dispatcher BAN COM 1600 DOS Redirector EPCBFS COM 57744 *****Options***** NetBIOS emulator PCNETB COM 38682 Asynch Term.

Buffer - add 1024 Bytes VINES 4.0 --------- With VINES 4.0, the DOS redirector "EPCBFS", is replaced by "REDIR3" or "REDIR4" depending on the DOS version used. If there is enough contiguous high memory (between 55K and 63K) use: ALLOAD REDIRn If not, REDIRn contains 37K of CODE and 18K - 26K of DATA, and has the capability of loading itself in two different addresses in the high memory area; the code segment will load into a 37K block and the data segment will require between 18K and 26K. The syntax is as follows: REDIRn /C:yyyy /D:zzzz, loads both segments high REDIRn /C:yyyy, loads high code segment only or REDIRn /D:zzzz, loads high data segment only where: n specifies the DOS version. /C:yyyy specifies load address for code segment /D:zzzz specifies load address for data segment NOTE: Before using these switches, the actual size of REDIRn has to be determined. This can be done by loading it into conventional memory. Since the CODE segment takes 37K, the size of the DATA segment can be determined by substracting 37K (37888 bytes) from the total size of REDIRn. Once the sizes are determined and you know how much high memory is available (use DOS MEMORY BLOCKs under ALLMENU) you will know if you can load the complete REDIRn, the CODE segment only, the DATA segment only or both CODE and DATA, in separate high memory locations. Since REDIRn itself takes charge of loading its CODE and DATA segments, and does not inform ALLEMM4 which addresses it uses in high memory, it is necessary to create and load "dummy" programs to protect the memory areas. IMPORTANT: If there is enough contiguous high memory available for REDIRn to load, then you do not need to create the DUMMY files for the CODE and DATA segments. You can simply ALLOAD REDIRn. In such a case your AUTOEXEC.BAT file will appear as follows: BAN /NC /NL ALLOAD TOKUIBAN (or other adapter) ALLOAD REDIRn CREATING DUMMY PROGRAMS FOR REDIRn ---------------------------------- Let's suppose that there is no space to load REDIRn in one high memory block, but the CODE and DATA segments can be loaded separatly to two different locations in high memory. The following will show you how to create and load two DUMMY files that will allocate the memory areas that REDIRn uses to load its segments into high memory: Using a text editor, create a file named CODE_SEG.SCR that will reserve a space of 37888 bytes (9400h) in high memory: N CODE_SEG.COM A MOV DX,9400 INT 27 <blank line> RCX 5 W Q <blank line> NOTE: Make sure that you have left an extra blank line after the "INT 27" and "Q" lines. Save the file as "CODE_SEG.SCR". Use the DOS DEBUG program to process the file: DEBUG < CODE_SEG.SCR This will create an executable file called CODE_SEG.COM that can be loaded into high memory using ALLOAD. It will allocate the memory required by the CODE segment of REDIRn. Create DATA_SEG.SCR in a similar way. In line three the ???? must be changed to a hexadecimal value which denotes the size of the DATA segment. For example, if the DATA segment requires 20512 bytes (21K) then the hexadecimal value used to replace ???? would be 5020. N DATA_SEG.COM A MOV DX,???? INT 27 <blank line> RCX 5 W Q <blank line> NOTE: Make sure that you have left an extra blank line after the "INT 27" and "Q" lines. Save the file as "DATA_SEG.SCR". Use the DOS DEBUG program to process the file: DEBUG < DATA_SEG.SCR This will create an executable file called DATA_SEG.COM that can be loaded into high memory using ALLOAD. It will allocate the memory required by the DATA segment of REDIRn. Once you have created the CODE and DATA DUMMY files for REDIRn you should re-boot your computer with the following changes in your AUTOEXEC.BAT file: BAN /NC /NL ALLOAD TOKUIBAN (or other adapter) ALLOAD CODE_SEG.COM ALLOAD DATA_SEG.COM Once completed, run ALLOAD (with no options) and note the addresses where CODE_SEG.COM and DATA_SEG.COM have loaded in high memory. The addresses for the CODE and DATA segments can then be included with the REDIRn command. AUTOEXEC.BAT: BAN /NC /NL ALLOAD TOKUIBAN ALLOAD CODE_SEG.COM ALLOAD DATA.SEG.COM REDIR3 /C:yyyy /D:zzzz <n_ Software Cbis Os LOADING CBIS NETWORK /OS INTO HIGH MEMORY ========================================== If your network adapter has any ROM, RAM or both which occupies addresses in reserved memory space (between 640K and 1024K) then: a) Set the network ROM/RAM to the beginning or end of a high memory block to minimize possible fragmentation or set the ROM/RAM addresses to the smallest high memory block (in cases where there is more than one high memory block). b) Exclude the ROM/RAM address range(s) you have selected for the network adapter with ALLEMM4.SYS and include the RAM option. DEVICE=ALLEMM4.SYS RAM X=<network adapter addr.> At the DOS prompt (or AUTOEXEC.BAT) use the Files, Buffers, Lastdrive and Device programs supplied to load these DOS resources into high memory. CBIS recommends that you run NWSTART /ARGS first as this should provide you with the information and parameters for the network. The following network files can be loaded high: NC .EXE 8K NX .EXE 19K to 28K SHARE .EXE 8K NR .EXE 42K NS .EXE 66K UBRIDGE .EXE 9K BRIDGE .EXE 19K to 32K Note that every configuration is different and that the examples given are intended only as a guide. Your configuration may be different from the examples shown. EXAMPLE ------- CONFIG.SYS: DEVICE=ALLEMM4.SYS RAM X=sp00-spFF * sp00 and spFF specify the start and end addresses of the range(s) to be excluded for the network adapter; the "s" represents the Segment and "p" is the Page of the address in hexadecimal. AUTOEXEC.BAT: FILES=20 BUFFERS=30 DEVICE=<network_card_driver_filename.SYS> REM If there is a Network Card driver REM it should go here. ALLOAD NC ALLOAD NX ALLOAD SHARE ALLOAD NR ALLOAD NS ALLOAD UBRIDGE ALLOAD BRIDGE <n_ Software 3Com = LOADING 3COM 3+ OPEN INTO HIGH MEMORY ===================================== If your network adapter has any ROM, RAM or both which occupies addresses in reserved memory space (between 640K and 1024K) then: a) Set the network ROM/RAM to the beginning or end of a high memory block to minimize possible fragmentation or set the ROM/RAM addresses to the smallest high memory block (in cases where there is more than one high memory block). b) Exclude the ROM/RAM address range(s) you have selected for the network adapter with ALLEMM4.SYS and include the RAM option. DEVICE=ALLEMM4.SYS RAM X=<network adapter addr.> At the DOS prompt (or AUTOEXEC.BAT) use the Files, Buffers, Lastdrive and Device programs supplied to load these DOS resources into high memory. Please remember that every system configuration is different and the examples given are intended as a guide. Your configuration may differ. EXAMPLE 1: 3+ Open Workstation with LAN Manager 1.0 --------------------------------------------------- Experience has shown that SPP.SYS needs to be loaded first in the first available block of memory above 640K. The order of the other device drivers does not matter, but the examples below were designed to obtain the best fit. CONFIG.SYS: DEVICE=ALLEMM4.SYS RAM X=C000-C3FF AUTOEXEC.BAT: rem 3+Open DOS LAN Manager 1.0 rem PS/2 Model 30-286, 50, 50Z, or 60 w/ 1MB rem & DOS 3.3 cd \all\util FILES=20 BUFFERS=20 LASTDRIV=Z rem SPP.SYS must be loaded first into the first rem segment DEVICE /AF =\3open\doswksta\lanman\drivers\SPP.SYS DEVICE /LM =\3open\doswksta\lanman\drivers\PRO.SYS ...12 20 2 DEVICE=\3open\doswksta\lanman\drivers\BUF.SYS DEVICE /LM =\3open\doswksta\lanman\drivers ...\ETH523.SYS DEVICE=\3open\doswksta\lanman\drivers\IDP.SYS DEVICE /LM =\3open\doswksta\lanman\drivers\LGL.SYS cd \ rem 3+Open DOS LAN Manager 1.0 break on prompt = $p$g set home_server=dark_overlord set home_server_security=user set screen=color.ini rem initialize network path=\3open\doswksta\lanman\drivers runminds mindspro mindsbuf mindseth mindsidp mindsspp mindslgl rem load NETBIOS and MINSES into high memory rem with ALLOAD cd \3open\doswksta\lanman\drivers if errorlevel 1 goto Error_Netbios \all\util\alload netbios if errorlevel 1 goto Error_Netbios \all\util\alload /LM minses12 if errorlevel 1 goto Error_Netbios cd \ path=\3open\doswksta\lanman net start workstation ...etc. EXAMPLE 2: 3+ Open Workstation with LAN Manager 1.1 --------------------------------------------------- CONFIG.SYS: device=c:\all\ALLEMM4.SYS RAM shell=c:\command.com /e:256 /p device=c:\3open\doswksta\lanman\drivers\PROTMAN.DOS .../I:c:\3open\doswksta\lanman\drivers device=c:\3open\doswksta\lanman\drivers\XNSTP.DOS NOTE: PROTMAN.DOS and XNSTP.DOS can not be loaded into high memory and must remain in your CONFIG.SYS file.

If using VGA video, the free available DOS memory is about 587K. APPLICATION NOTES ----------------- MINSES pre 1/27/86 and NB (NetBios) pre 8/12/87 will not work. If you have these you must update them. On 3Com's 3+ network operating system, if the full NetBIOS must be loaded into high memory, you must use NetBIOS 1.2.1H (available to 3+ customers from 3Com and is included with 3Com 3+Open systems). Use the IBM PS/2 Reference Diskette to relocate the RAM Packet Buffer of the EtherLink /MC card to address C000-C5FF. Although the documentation specifies that the ETH523 card RAM Packet Buffer is 24K, it really only uses 16K. Thus, you need only exclude 16K rather than 24K with ALLEMM4. FOR 3+OPEN only: In the LANMAN.INI file, you will find the line containing the "redir" command. Append the beginning of the line to include the full path of ALLOAD. \<path>\ALLOAD REDIR <n_ Software PCSA Decnet = LOADING PCSA DECNET INTO HIGH MEMORY ==================================== If your network adapter has any ROM, RAM or both which occupies addresses in reserved memory space (between 640K and 1024K) then: a) Set the network ROM/RAM to the beginning or end of a high memory block to minimize possible fragmentation or set the ROM/RAM addresses to the smallest high memory block (in cases where there is more than one high memory block). b) Exclude the ROM/RAM address range(s) you have selected for the network adapter with ALLEMM4.SYS and include the RAM option. DEVICE=ALLEMM4.SYS RAM X=<network adapter addr.> At the DOS prompt (or AUTOEXEC.BAT) use the Files, Buffers, Lastdrive and Device programs supplied to load these DOS resources into high memory. CONFIGURING DEPCA BOARD MEMORY MODES (W7 & W8) ---------------------------------------------- The function of JUMPERs W7 and W8 is dependant on the revision level of the DEPCA board and the version of DECnet PC software that you are using. DEPCA revision E (or later) is compatible with all versions of DECnet PC software. However, in order to use the 32K memory mode on revision E (or later) DEPCA, you must be running DECnet PC software that supports this feature. See your DECnet PC Software Product Description to verify 32K mode. If you have a DEPCA board with revision letter D, call your local DEC supplier for the W7 and W8 settings. For Revision E cards, follow the settings below: W7 W8 MODE START ADDRESS -- -- ---- ------------- IN IN 64K D000 OUT IN 64K E000 IN OUT 32K D800 OUT OUT 32K C800 NOTE: JUMPERs W7 and W8 are found above the bus contact teeth in the middle of the board.

EXAMPLE 2 -- 10NET Version 4.20.00 ---------------------------------- The 10NET program called 10NET.EXE is an exploding/ imploding program that initially uses 170K of RAM and shrinks to between 80K and 100K. 10NET has a feature which will automatically load the CODE and DATA segments of 10NET.EXE into high memory by specifying two options to the SYSSVC program. You should load your system as follows: CONFIG.SYS: DEVICE=C:\ALL\ALLEMM4.SYS RAM FR=NONE AUTOEXEC.BAT: prompt $p$g path ...

You should then run ALLOAD to identify the free high memory areas. If you have a free high memory block large enough to fit the combined total of the 10NET.EXE CODE and DATA requirements, then make the following adjustments to the SYSSVC line in your AUTOEXEC.BAT file: SYSSVC /10NET=X,Y /RAM=Z,T where: X is the size of the CODE segment in kilobytes Y is the size of the DATA segment in kilobytes Z is the start address of the free high memory block in hexadecimal T is the total size of the CODE and DATA segments in kilobytes (ie. T=X+Y) When the 10NET program executes it will allocate itself into conventional memory, and SYSSVC will then load it into high memory at the address specified in the /RAM option.

When executed UMMGR allows READYNET to relocated itself into high memory. This high memory is provided independently by ALLEMM4.SYS in your CONFIG.SYS file as follows: DEVICE=ALLEMM4.SYS RAM <other options> If the READYNET overhead is very large, you may wish to use the FR=NONE option with ALLEMM4 to gain a further 64K of high memory: DEVICE=ALLEMM4.SYS RAM FR=NONE In order for UMMGR to load READYNET above 640K you must specify the address range of each high memory block you would like READYNET to use. The address must be included when UMMGR is executed, in the form: UMMGR sp00-spFF or UMMGR sp00 sp00-spff * sp00 and spFF specify the start and end addresses of the high memory range(s) to be used by READYNET; the "s" represents the Segment and "p" is the Page of the address in hexadecimal. If you run ALLOAD with no parameters you can get the address(es) of the high memory blocks for UMMGR. Please remember that every system configuration is different and the examples given are intended as a guide. Your configuration may differ.

NOTE: Once a high memory block is allocated by UMMGR cannot be used to load any other TSR or DOS resource. You will not be able to use the Files, Buffers, Lastdrive, Device or ALLOAD loaders to move other overhead into high memory. <n_ Software Dlink = LOADING D-LINK INTO HIGH MEMORY =============================== D-LINKS's LANSMART network can be installed as either a workstation or a server. The adapter card provided is an ETHERNET (DE-100) with a 16K ROM memory address set at D000-D3FF by default. The ROM address should be changed to a more optimum location by setting the three sets of three-pin jumpers at JP5: JUMPER SETTING ADDRESSES #1 #2 #3 --------- -- -- -- C000-C3FF 0 0 0 C400-C7FF 1 0 0 C800-CBFF 0 1 0 CC00-CFFF 1 1 0 D000-D3FF 0 0 1 D400-D7FF 1 0 1 D800-DBFF 0 1 1 DC00-DFFF 1 1 1 If you have monochrome or CGA video set the ROM at C000-C3FF. If you have an EGA card with 16K of video ROM, set the DE-100 at C400-C7FF. For EGA systems with 32K of video ROM, or VGA systems set the DE-100 ROM at C800-CBFF. EXAMPLE: To set the adapter board for address C800-CBFF the JUMPER block should look like this: 1| |X| | |-|-|-| X = Jumpered 0|X| |X| - JP5 - Once you have physically excluded the ROM address range you have selected for the DE-100 network adapter you should set an exclude statement with ALLEMM4.SYS and specify the RAM option, in your CONFIG.SYS file. DEVICE=ALLEMM4.SYS RAM X=<network adapter addr.> At the DOS prompt (or AUTOEXEC.BAT) use the Files, Buffers, Lastdrive and Device programs supplied to load these DOS resources into high memory.
