Hi,
I have successfully added a DR-DOS partition to a MS-DOS 7.1 (win98)
system, but I didn't use DR-DOS's fdisk ;-)
BTW, I lost the message with the information about what should be in
the OEM signature to be MS-DOS compatible. Can someone please
resend it to me? :)
I found a problem in DR-DOS about the dive letters assigment. Let me
describe it: if I have a drive (only one) with _two_ primary partitions and
an extended partition, MS-DOS uses the active partition as C:, the
extended partition as D: and the other extended partition as E:. This is a
general rule: extra primary partitions go at the end. With DR-DOS, the
first extended partition is C:, and the second is D:, leaving the extended
partition as E:. The biggest problem is that if you put DR-DOS in the
second partition it _cannot_ boot as it changes from C: to D: in the middle
of the boot process. So if you want to have more than one partition
to select which is active, DR-DOS HAS TO BE in the first one. I don't
know for sure, but this may also afect DR-DOS+Linux in the same drive...
