Apple 4400, 7300 manual Setting up your DOS configuration files, Editing the CONFIG.SYS file

Setting up your DOS configuration files

When you install the PC Compatibility Card software, it makes all the necessary modifications to your DOS CONFIG.SYS and AUTOEXEC.BAT files. However, there may be times when you want to modify these files. Follow these guidelines:

Editing the CONFIG.SYS file

Your CONFIG.SYS files should include the following statements:

DOS=HIGH,UMB

STACKS=9,256

DEVICE=C:\DOS\HIMEM.SYS /TESTMEM:OFF

DEVICE=C:\DOS\EMM386.EXE NOEMS

LASTDRIVE=M

DEVICEHIGH=C:\APPLE\CDROM.SYS /D:CDDRVR

INSTALLHIGH=C:\APPLE\MACSHARE.COM

The first line loads DOS into high memory.

If you’re using the DOS utility EMM386 and you don’t require expanded memory, use all the statements shown above. If you are using EMM386 and you do require expanded memory, remove the following line:

DEVICE=C:\DOS\EMM386.EXE NOEMS

and replace it with this line:

DEVICE=C:\DOS\EMM386.EXE

For more information on making the best use of memory, see the information on memory management in the documentation for DOS or for your memory manager.

The last two lines load the CD-ROM drive software and file-sharing software into high memory.
