- Alpha FOUR and DOS
-
- Introduction:
- Every piece of commercial software made to run under DOS has
- hardware and operating system configuration requirements in order
- to function as it was designed to. Alpha FOUR is no exception to
- this rule. This document is being provided to help you better
- understand what Alpha needs from your computer, and give you tips
- on how to provide Alpha FOUR with what it needs. This will ensure
- that you get the best performance from your hardware, and Alpha
- FOUR.
-
- Requirements:
- As stated in the manual, the reqirements for proper (but not
- neccesarily optimal) performance of Alpha FOUR are as follows:
- 1) An IBM (or compatible) computer,
- 2) 640K RAM,
- 3) DOS 3.1 or higher,
- 4) A floppy drive,
- 5) A hard drive.
- These are minimum requirements, NOT what we recommend. Although
- Alpha FOUR will function under the above conditions, it can work
- faster and more efficiently with more memory (2 megabytes or
- more), a fast processor (386/20 or above), and MS-DOS 5.0 or
- newer. These are our recommendations, and chances are, (if you
- purchased your machine within the past 2 years) your system
- already has these. The following instructions assume that your
- system meets our RECOMMENDED requirements.
-
- Configuring your System:
- Below are examples of CONFIG.SYS and AUTOEXEC.BAT files
- containing the lines we suggest using. If you are not sure what
- a given line in your current file does, try remarking it out (by
- putting "REM " {without quotes} in front of the line). REM causes
- that line to be ignored by DOS. This will allow you to see what's
- missing like something that worked before, that doesn't work now.
- If you don't notice any difference, leave the line "REMarked"out.
-
- MAKE SURE YOU HAVE A BOOT DISK HANDY BEFORE MAKING ANY CHANGES!
- If you don't have a bootable floppy, make one now by putting a
- blank floppy in the A: drive and type format a:/s at the c: prompt.
- (If you're running MS-DOS 6.0, don't bother, you can hit F8)
- This bootable floppy will serve two purposes; First, it
- will let you into your system in case you make a mistake editing
- the startup files. Second, it will provide an easy way to boot
- with "Plain Vanilla DOS"... This is the flavor of DOS that has
- only DOS' defaults. (No config or autoexec, therefore no device
- drivers or TSR's; memory resident programs). Using EDIT.COM or
- your favorite ASCII editor, change your CONFIG.SYS and
- AUTOEXEC.BAT files to look like the file contents presented
- below, categorized by the amount of memory installed in your
- system.
-
- For systems with 2 megs ram:
- CONFIG.SYS:
- DOS=HIGH,UMB
- DEVICE=C:\DOS\HIMEM.SYS
- DEVICEHIGH=C:\DOS\EMM386.EXE RAM 512
- DEVICEHIGH=C:\DOS\SMARTDRV.SYS 256 (If you don't have
- FILES=60 Windows)
- BUFFERS=20
-
- AUTOEXEC.BAT:
- @ECHO OFF
- LH C:\WINDOWS\SMARTDRV.EXE 256 (If you have Windows)
- LH C:\DOS\SHARE.EXE
- PROMPT $P$G
- PATH C:\;C:\DOS
-
-
- For systems with 4 or more megs ram:
- CONFIG.SYS:
- DOS=HIGH,UMB
- DEVICE=C:\DOS\HIMEM.SYS
- DEVICEHIGH=C:\DOS\EMM386.EXE RAM 2048
- DEVICEHIGH=C:\DOS\SMARTDRV.SYS (If you don't have
- FILES=60 Windows)
- BUFFERS=20
-
- AUTOEXEC.BAT:
- @ECHO OFF
- LH C:\WINDOWS\SMARTDRV.EXE (If you have Windows)
- LH C:\DOS\SHARE.EXE
- PROMPT $P$G
- PATH C:\;C:\DOS
-
- Notes:
- You'll notice the optional smartdrv lines in the above examples;
- Use only one, or the other, depending upon what appears in
- parenthesis at the end of the line. DON'T INCLUDE WHAT'S IN
- THE PARENTHESIS IN YOUR FILES. If you're running MS-DOS 6.0,
- and don't have Windows, you MUST use the SMARTDRV.EXE that comes
- with DOS 6. (because there is no smartdrv.sys)
- Simply adjust the path to it accordingly: (LH C:\DOS\SMARTDRV.EXE)
- Please note that we have set BUFFERS to 20, this is so that
- the smartdrv cache can do it's job more efficiently.
- If you're not using a disk cache, set BUFFERS to 32.
-
- Additional Considerations:
- Most people will have other TSR's and device drivers loading in
- addition to those in the above examples. If you do, make sure to
- load them into high ram, by using the command DEVICEHIGH (in the
- CONFIG.SYS file) or LOADHIGH (LH) (in the AUTOEXEC.BAT file).
- Doing so will give you more free conventional memory to work
- with. There will be a limit as to how much will be able to load
- up there, but if DOS runs out of room in the high memory area, it
- will just quietly load your program into conventional instead.
