Apple Macintosh LC 630 DOS - Manual (Page 138)

If you do not intend to use software that requires expanded memory (EMS),
make the following change:
DEVICE=C:\DOS\EMM386.EXE NOEMS RAM=D000-EFFF
If you intend to use software that does use expanded memory, or you’re
unsure what you may need in the future, make the following change:
DEVICE=C:\DOS\EMM386.EXE RAM=D000-EFFF FRAME=D000
Depending on how you have reconfigured the file, your CONFIG.SYS file
should look something like this:
DEVICE=C:\DOS\SETVER.EXE
DEVICE=C:\DOS\HIMEM.SYS /TESTMEM:OFF
DEVICE=C:\DOS\EMM386.EXE RAM=D000-EFFF FRAME=D000
DOS=HIGH,UMB
FILES=30
LASTDRIVE=M
Additionally, your AUTOEXEC.BAT file should contain the following:
LH C:\DOS\SMARTDRV.EXE /X
@ECHO OFF
PROMPT $p$g
PATH C:\WINDOWS;C:\DOS
SET TEMP=C:\DOS
(The reference to Windows in the PATH line applies only if you chose to
install Windows.)
See your DOS manual to learn how to edit and save your DOS files.
IMPORTANT Some memory configuration utilities, such as MEMMAKER,
may not be able to determine the exact nature of the hardware of the DOS-
compatible computer and, therefore, may not be compatible. Additionally,
using third-party compression software such as DriveSpace on a drive
container prevents you from accessing the container or the files within it
from the Mac OS. For these reasons, Apple does not recommend using these
programs with your DOS-compatible computer.
