MIXED BC/SI SCREEN OR BPM ON STACK DOESN'T WORK ------------------------------------------------------------------- 1. INSTALLING WITH DOS 5 OR DOS 6 ------------------------------------------------------------------- S-ICE.EXE must be the EMS memory manager (do not use EMM386). HIMEM.SYS must be after S-ICE.EXE, not before. When HIMEM.SYS is loaded, it displays the message "Installed A20 Handler" followed by a number. If the number is not "1" or "2", you must use the switch "/m:1" with HIMEM.SYS. DOS 5.0/6.0 may be loaded high with the "dos = high" command. Note that HIMEM.SYS must be installed to use this. If you wish to load drivers and T&SR's high, you must configure S-ICE.EXE for this using EMMSETUP. If you do not have our utility UMB.SYS, you must use our Load High utilities (LD.SYS and LH.EXE). Since the DOS 5.0/6.0 load high utility is called by "LH", rename ours to LHIGH.EXE or specify the full path to LH.EXE. You cannot use "dos = umb". Your CONFIG.SYS file should look something like this: dos = high device = c:\si\ce.exe ;configuration editor device = c:\si\s-ice.exe /SYM 500 /EXT 2112 /EMM device = c:\dos\himem.sys /m:1 device = c:\si\ld.sys c:\ansi.sys device = c:\si\ld.sys c:\dos\smartdrv.sys 2048 etc... If you have UMB.SYS, you may install this driver to allow using the DOS 5/6 UMB functions and load-high utilities. In this case your CONFIG.SYS file would look something like this (note that the "dos=high" line has been changed to "dos=high,umb"): dos = high,umb device = c:\si\ce.exe ;configuration editor device = c:\si\s-ice.exe /SYM 500 /EXT 2112 /EMM device = c:\dos\himem.sys /m:1 device = c:\si\umb.sys devicehigh = c:\ansi.sys devicehigh = c:\dos\smartdrv.sys 2048 etc... NOTE: The /EXT 2112 switch in the examples above reserves 64K of XMS memory for HIMEM.SYS (to load DOS high) and 2048K of XMS memory for SMARTDRV.SYS. The amount needed may differ depending on what drivers are loaded and how much XMS memory each uses: the value of was chosen to fit this example. For example, if you use the DOS 6 SMARTDRV.EXE, it may use up to 8M of XMS memory for the cache. DOS 6 NOTE: The disk compression driver DBLSPACE (which is about 43K long) cannot be loaded high using Nu-Mega's LD.SYS utility. You must use UMB.SYS and the DOS 6.0 "devicehigh" command. ------------------------------------------------------------------- 2. OVER 16M MEMORY OR 16M MEMORY NOMINAL ------------------------------------------------------------------- Problem: Over 16M memory, keeps rebooting when trying to install Symptom: "S-ICE is loaded" message has start address of S-ICE larger than end address. Solution: patch s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -s 0 lffff b4 88 cd 15 (prints 2 addresses in xxxx:yyyy format) -e first-address b8 00 3b 90 -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 3. COMPAQ REBOOTS ------------------------------------------------------------------- Problem: SL based/non-BIMM Compaq system reboots when s-ice.exe is installed. Solution: change s-ice.exe as follows (NOTE - the syntax "cs+2000" means add 2000 hex to the contents of the CS register and key in this number): ren s-ice.exe s-ice.bin debug s-ice.bin -s 0 lffff '03C' (prints an address in xxxx:yyyy format) -e address ff -r (get CS) -s cs+2000:0 lffff '03C' (prints an address in xxxx:yyyy format) -e address ff -w -q ren s-ice.bin s-ice.exe Also, if the keyword COMPAQ is in the S-ICE.DAT file, comment it out with a semicolon. NOTE: This problem has also occurred on other brands of computer which used a Compaq BIOS to control an IDE disk drive. ------------------------------------------------------------------- 4. LOAD HI AREA IS NOT CLEARED ON WARM BOOT ------------------------------------------------------------------- Problem: On CTRL-ALT-DEL the programs loaded high remain in place so no space is available to load high. Solution: Erase the first 16 bytes of the 1st load high area. The program ZERO.SYS should be loaded immediately after Soft-ICE in the CONFIG.SYS file to do this automatically upon rebooting. ------------------------------------------------------------------- 5. COMPAQ ProSignia 486 WITH EISA SCSI DRIVE (VIRTUAL DMA) ------------------------------------------------------------------- Problem: On bootup, displays a message that the current EMS memory manager does not support Virtual DMA. Solution: Load the driver SCSIC710.SYS in your CONFIG.SYS file.This driver is available on our BBS or from Compaq. The load syntax is as follows: DEVICE = [drive:][path]SCSIC710.SYS [/N] [/D] PARAMETERS: /N This parameter directs SCSIC710 not to display on-screen messages. /D This parameter forces SCSIC710 to always use double buffering. NOTE: When using this driver in conjunction with Compaq's EXTDISK.SYS, EXTDISK must be loaded first. ------------------------------------------------------------------- 6. USING SOFT-ICE ON A PENTIUM SYSTEM ------------------------------------------------------------------- The following changes must be made when using Soft-ICE on a Pentium system (NOTE - the syntax "cs+2000" means add 2000 Hex to the contents of the CS register and key in this number): ren s-ice.exe s-ice.bin debug s-ice.bin -r (get CS) -s cs+2000:0 lffff 2e 83 06 (prints an address in xxxx:yyyy format) -e address 64 -s cs+2000:0 lffff 2e c7 06 (prints two addresses in xxxx:yyyy format) -e first-address 64 -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 7. SOURCE OUT OF SYNCH OR NO SOURCE DISPLAY ------------------------------------------------------------------- Problem: Source display is out of sychronism or no source is displayed. Solution: There are 3 reasons why this happens: A header file (.h) has code or data within it. These files should contain definitions and declarations only. This is the only reason which applies to C language programs. A module has no public symbol at the start, or has no public symbols. This can occur in Pascal, Assembly and some other languages. A code module is not class "CODE". The linker will put this module after the Data, separated from the rest of the Code. This only applies to Assembly language programs. ------------------------------------------------------------------- 8. NO SOURCE DISPLAY OR CANNOT FIND SOURCE ------------------------------------------------------------------- Problem: no source display or cannot find source files Reasons why no source display: 1: no debug data in the .EXE file, and no .SYM file 2: not enough /SYM space reserved 3: no source line # info in debug data 4: used LDR program-name.EXE Reasons why cannot find source files: 1. used path to LDR (becomes default path) 2. did not SET SRC=.... 3. source files not in current directory ------------------------------------------------------------------- 9. CTRL-ALT-DEL DOESN'T WORK ------------------------------------------------------------------- Problem: Ctrl-Alt-Del won't reboot on IBM Model 55SX, Dell, Northgate, DTK, AST and some other systems. Solution: The keyboard controller on these systems does not recognize the reboot command (send FE to port 64). To fix this, change s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -s cs:0 lffff b0 fe e6 64 (prints 2 addresses in xxxx:yyyy format) -a address1 xxxx:yyyy NOP xxxx:yyyy+1 NOP xxxx:yyyy+2 NOP xxxx:yyyy+3 NOP xxxx:yyyy+4 MOV BX,1 xxxx:yyyy+7 (Enter) -a address2 xxxx:zzzz NOP xxxx:zzzz+1 NOP xxxx:zzzz+2 NOP xxxx:zzzz+3 NOP xxxx:zzzz+4 MOV BX,1 xxxx:zzzz+7 (Enter) -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 10. NETWORK TIMEOUT ------------------------------------------------------------------- Problem: Network disconnects when Soft-ICE is used. Solution: When the Soft-ICE screen is popped up, all interrupts are disabled. If it is left up too long, the server may disconnect your workstation from the network. You should exit Soft-ICE every 10 minutes to allow the network to access your computer. Alternatively, you may be able to increase the timeout. For Netware 3.x, you can control the timeout with SET statements from the console command line, or in AUTOEXEC.NCF. See README.SIW for more details. ------------------------------------------------------------------- 11. VCPI DOESN'T WORK ------------------------------------------------------------------- Problem: VCPI client programs like LOTUS, ORACLE etc. don't work. Solution: VCPI programs require the /EMM switch with at least 256K. ------------------------------------------------------------------- 12. FLOPPY HANGS WHEN SOFT-ICE INSTALLED (GP ERROR IN CACHE) ------------------------------------------------------------------- Problem: Floppy hangs when Soft-ICE is installed, on protected mode instruction in BIOS (F000:xxxx). Instruction is MOV EAX,CRx. Analysis: Some older Phoenix BIOS ROM's handled cache operations in protected mode. BIOS ROM must be replaced or you must update to Soft-ICE 2.6, which can emulate this instruction without generating a protection error. Some Gateway 2000 486's have this older BIOS. ------------------------------------------------------------------- 13. PROBLEM WITH JET KEYBOARD CONTROLLER ------------------------------------------------------------------- Problem: On systems with a JET Keyboard Controller chip, the keyboard hangs after Soft-ICE is entered and exited. Solution: Patch Soft-ICE as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -s 0 lffff b0 d0 e6 64 (prints address in xxxx:yyyy format) -e yyyy+1 ee (change d0 to ee) -e yyyy+3 60 (change 64 to 60) -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 14. OUT OF SYMBOL SPACE ------------------------------------------------------------------- Problem: LDR prints "out of symbol space" Solution: This results when the LDR.EXE for version 2.0/2.1 is used and version 2.5/2.6 S-ICE.EXE is loaded. ------------------------------------------------------------------- 15. BPINT 2 BYTES OFF IN CODE ------------------------------------------------------------------- Problem: BPINT breakpoint displays code 2 bytes ahead of actual INT. Solution: "BREAK ON" is set in S-ICE.DAT. Delete it. ------------------------------------------------------------------- 16. ALT-SYS-RQ HANGS ON EXIT ------------------------------------------------------------------- Problem: On some systems, when Alt-Sys-Rq key is assigned to pop up Soft-Ice, the system hangs upon exit. Solution: there is a timing problem in some systems because of the length of time it takes to complete the analysis of this key, and so the system gets stuck in the "Alt On" state. The user either must press the Alt key to release this state before exiting, or must assign a different key to pop up Soft-ICE. ------------------------------------------------------------------- 17. TURBO DEBUGGER IN 43-LINE MODE ------------------------------------------------------------------- Problem: Soft-ICE with Turbo Debugger in 43 line mode beeps and dies. Solution: patch s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -r (get value of CS register) -e (cs+1000h):b993 7f -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 18. MCV HANGS WITH CV 3.14 ------------------------------------------------------------------- Problem: CodeView 3.14 called through MCV hangs up Solution: patch s-ice.exe as follows ren s-ice.exe s-ice.bin debug s-ice.bin -s cs:0 lffff 42 22 (prints address in xxxx:yyyy format) -e xxxx:yyyy+1 1e (change 22 to 1e) -s cs:0 lffff 5a 20 (prints 2 addresses) -e xxxx:wwww+1 1c (change 20 to 1c in both locations) -e xxxx:zzzz+1 1c -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 19. WRONG LINE #'S IN "STACK" COMMAND ------------------------------------------------------------------- Problem: Line numbers displayed by STACK command are wrong, typically very large (28xxx) Solution: patch s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -e cs:626f (should print "08.") 0a (change 08 to 0a) -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 20. PROTECTED MODE COMPILE OR USING CV 3.11/3.14 W/O MCV ------------------------------------------------------------------- Problem: Protected mode compiling with MSC 6.0 or running CV3.11 or 3.14 without MCV Solution: patch s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -s cs:0 lffff eb 03 cb (prints address in xxxx:yyyy format; offset should be 947E) -e xxxx:yyyy fa eb 02 -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 21. GP ERROR DISASSEMBLING OR STEPPING THRU CODE ------------------------------------------------------------------- Problem: General Protection Error when disassembling or stepping thru code. Solution: patch s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -s cs:0 lffff 81 7c 01 4e 56 74 (prints address in xxxx:yyyy format; offset should be E3D8) -e xxxx:yyyy 90 90 90 90 90 90 90 90 90 90 90 90 90 (13 NOP's) -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 22. ACTION NMI DOESN'T TRANSFER TO CV ------------------------------------------------------------------- Problem: ACTION NMI doesn't transfer control to CodeView Solution: BPX won't work with NMI, must use BPM-X. Also must set up CodeView to intercept NMI. ------------------------------------------------------------------- 23. BACK TRACE DOESN'T WORK ------------------------------------------------------------------- Problem: Back Trace operation doesn't work Solution: If Soft-ICE is being run with Bounds-Checker, BC monopolizes the Paging hardware, so the BPR commands in Soft-ICE do not work. The "BOUNDS OFF" command does not help. The only solution is to run Soft-ICE separately. ------------------------------------------------------------------- 24. KEYBOARD LOCKS AFTER NUM-LOCK OR CAPS-LOCK ------------------------------------------------------------------- Problem: Keyboard locks up after keying NUM-LOCK or CAPS-LOCK Solution: Some early AMI BIOS ROM's have a timing problem in the keyboard controller. Boot the system and read the BIOS serial number: if it ends with KA,KB,KC,KD,KE or KF, this is one of the bad chips. Even though AMI has not made these chips since 1986, some computer manufacturers still have them in stock. The only solution is to replace the keyboard controller chip. AMI contact: Sam on 404-263-8181. ------------------------------------------------------------------- 25. .EXE NOT FOUND ------------------------------------------------------------------- Problem: Message ".EXE not found" displayed when doing LDR xxx.SYM on a driver Solution: make a .EXE file by copying the .SYM file. ------------------------------------------------------------------- 26. LONG PATH TO .EXE FILE IS TRUNCATED ------------------------------------------------------------------- Problem: Using LDR with long path to .EXE file, can't find file, prints truncated path. Solution: Use the SUBST command to create a virtual drive for a long path. ------------------------------------------------------------------- 27. .COM FILE ------------------------------------------------------------------- Problem: .COM file will not load properly Solution: Delete the .EXE file ------------------------------------------------------------------- 28. PRT-SC NOT WORKING ON OLD-STYLE KEYBOARD ------------------------------------------------------------------- Problem: Print Screen doesn't work with old (100) keyboard. Solution: change s-ice.exe as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -s cs:0 lffff 80 fc 47 (prints address) -u address kkkk:nnnn CMP AH,47 . . . kkkk:mmmm TEST BYTE PTR [ZZZZ],20 . . . kkkk:nnnn CMP AL,2A kkkk:pppp JZ XXXX kkkk:qqqq CMP BYTE PTR [YYYY],00 kkkk:rrrr JZ WWWW Change last two lines to: kkkk:qqqq TEST BYTE PTR [ZZZZ],20 kkkk:rrrr JNZ WWWW Typically this is f6 06 19 0a 20 75 (ZZZZ = 0A19) -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 29. "INT 10 DOES NOT POINT TO..." ------------------------------------------------------------------- Problem: displays message "INT 10 does not point to E000" Solution: This message is displayed when the Video card is a Hercules graphics adapter or some monochrome cards. Patch Soft-ICE as follows: ren s-ice.exe s-ice.bin debug s-ice.bin -r (get CS) -s cs+2000:0 lffff b8 00 e0 (prints address in xxxx:yyyy format) -e xxxx:yyyy+2 ff (change e0 to ff) -w -q ren s-ice.bin s-ice.exe ------------------------------------------------------------------- 30. "ENTER PATH..." FOR BORLAND C++ ------------------------------------------------------------------- Problem: Prints "enter path for" for all source files. Solution: Patch LDR.EXE as follows: ren ldr.exe ldr.bin debug ldr.exe -e 8cec 02. 03 (change 02 to 03) -w -q ren ldr.bin ldr.exe ------------------------------------------------------------------- 31. SNOW ON SCREEN WHEN USING WINDOWS (REAL MODE) ------------------------------------------------------------------- Problem: Snow on screen when using Soft-ICE with Windows 3.0 in real mode. Solution: Increase the Windows space by decreasing the /TRA and /SYM space used by Soft-ICE. ------------------------------------------------------------------- 32. VERTICAL LINES ON SCREEN ------------------------------------------------------------------- Problem: Vertical lines on the screen when running graphics programs. Solution: EMM Map is set up for backfilling; run EMMSETUP and restore A000 block to VVVV so video memory is not being accessed incorrectly. ------------------------------------------------------------------- 33. TAPE BACKUP DOESN'T WORK WHEN S-ICE INSTALLED ------------------------------------------------------------------- Problem: The tape backup fails. Solution: This is caused by the time that Soft-ICE takes up during an interrupt call. It can result from Soft-ICE being loaded into 16-bit memory. Try loading Soft-ICE into 32-bit extended memory and see if that works. Also, unload Soft-ICE thru "S-ICE /U" on the command line. Then do the tape backup and reload Soft-ICE thru "S-ICE". ------------------------------------------------------------------- 34. OLIVETTI LAPTOP KYBD LOCKS UP ------------------------------------------------------------------- Problem: Keyboard locks up on SCROLL LOCK, NUM LOCK or CAPS LOCK on an Olivetti laptop (M316) with Olivetti BIOS. Solution: Install Lantistic's KBFLOW program. This is public domain software. ------------------------------------------------------------------- 35. KEYBOARD 1 CHAR OFF ------------------------------------------------------------------- Problem: Keyboard is 1 character behind the actual keystrokes. Solution: This problem occurred when the program LAN MAN REDIRECTOR was installed. ------------------------------------------------------------------- 36. PROGRAM BLOWS UP WHEN LOADED WITH LDR ------------------------------------------------------------------- Problem: Program loads OK, but blows up when loaded with LDR. Solution: LDR changes the stack by 1 word. If the initialization code uses absolute offsets to read data from the stack, it will read the wrong locations. ------------------------------------------------------------------- 37. BPAND DOESN'T WORK ------------------------------------------------------------------- The BPAND command does not work for BPX type breakpoints. This includes F9 style point-and-shoot breakpoints. You must use a hardware type of breakpoint such as BPIO or BPM X. Also, the order in which the breakpoints are listed in the BPAND command is not significant; they do not have to occur in that specific order. The break will occur when all the breakpoints listed have occurred at least once. ------------------------------------------------------------------- 38. USING SOFT-ICE 2.5x & EARLIER WITH MICROSOFT C/C++ 7.00 ------------------------------------------------------------------- Problem: With the C/C++ 7.00 compiler, Microsoft changed the format of the CodeView debug data. Solution: Soft-ICE cannot read the C/C++ debug data directly from the .EXE file. Use the MSYM method as follows: Link without the "/CO" switch but with the "/MA" and "/LI" switches. After linking, run our MSYM.EXE utility on the .MAP file to create a .SYM file which contains the debug data. If there is no debug data in the .EXE file, Soft-ICE will look for a .SYM file. You should use MSYM version 2.4 (dated 8/24/92) or later; it can be downloaded from this BBS. Earlier versions may work in some cases. NOTE: Microsoft's MAPSYM utility may create a .SYM file as part of the compilation process. This .SYM file does not contain all the debug data needed by Soft-ICE. You must use our MSYM. ------------------------------------------------------------------- 39. MIXED BC/SI SCREEN OR BPM ON STACK DOESN'T WORK ------------------------------------------------------------------- Problem: Mixed BC/SI screen, or BPM that doesn't catch a change on the stack. Solution: This can occur when a stack is outside the program space and Bounds-Checker is being run with Soft-ICE. If a CALL is made, a Page Fault occurs when the return address is written to the stack, and it overwrites the return address. Also, if there is a breakpoint on a PUSH instruction, before the Bounds-Checker screen is completely written, it is overwritten by the Soft-ICE screen. One way to identify this type of problem is that it won't happen if Soft-ICE is single-stepped. The only cure is to change to a stack within the program space. -------------------------------------------------------------------
