Edit (or create) config.sys on the root of Drive C. The contents should be similar to the following:
[menu]
menuitem=Linux, Mandrake Linux 7.2
menuitem=Win98, Windows 98
menucolor=15,1
menudefault=Win98, 10
[linux]
[win98]
If your system already has a config.sys file, put those contents under
the [win98] section. The [linux] section is left blank
intentionally.
Edit (or create) autoexec.bat on the root of Drive C. The contents
should be similar to the following:
goto %config%
:linux
call c:\linux.bat
:win98
As above, if you aready have an autoexec.bat file, put those contents
under the :win98 section.
Create a file called: linux.bat. Putting it in the root of
Drive C is as good as place as any (but it can go anywhere so long
as you reference the path or location). The contents should be
similar to the following:
@echo off
c:\loadlin c:\vmlinuz root=/dev/hda3 ro
The above example assumes that loadlin.exe and vmlinuz are
located in the root of Drive C (or C:\) and that linux is installed on the
/dev/hda3 partition. Your configuration may be different.
The important thing here is to make sure that loadlin and your linux kernel file are properly referenced. Finished!
That should work for you, as that is how I have things set up on my system, which dual boots with Win98.
