No, I've created a bootdisk with just 3 files on it: ibmbio.com,
ibmdos.com and command.com, copied drfat32.* and written
apropriate config.sys/autoexec.bat
Is DPMS necessary for drfat32.exe ?
Anyway here's the scenario. I have a boot manager starting the
computer in DOS 6.22 or Win98. The partition are set up as such
Boot Magic
1st Primary DOS - FAT16 - 350Megs
2nd Primary Win98 - FAT32 - 3.5Gig (which goes past the 2Gig barrier)
Extended partition - 15Gig divided into 3 parts.
One = 2Gig - FAT16
Two = 2Gig - FAT16
Three = 3.5Gig - FAT32 (this one starts before the 8Gig barrier, but
goes beyond it.)
The rest is hidden for backup purpose's.
DOS can't see the two other FAT16 partition. This may be because the
Extended partition starts after the 2Gig mark. Do you think drfat32
would handle this? Is drfat32.exe MSDOS? Or does the dr mean its a
DRDOS program? And, if so how does NT4 deal with drfat32 and/or
DRDOS?

1. The problem DOS 6.x can't see some partitions may be caused
by the fact their type ids in partition table are unknown
to DOS: DOS 6.x can see partitions of type 05 (Extended)
and 06 (FAT16 >32MB), but it doesn't recognize types
0F (Extended using LBA) nor 0E (FAT16 >32MB using LBA).
Use diskedit to check the partitions' types.
2. drfat32 is an add-on to DR-DOS, it should make FAT32
partitions visible (it doesn't work for me), anyway
you can download it from http://www.drdos.org/ and try
it.
3. drfat32 is a DOS driver, so it won't work under Windows NT
at all.
