RY> What brought about this doubt is this scenario :
RY> Some time ago, I had 2 FAT and 2 HPFS partitions (1 FAT and 1 HPFS was
RY> the primary).
RY> 1. Boot Manager
RY> 2. FAT (primary)
RY> 3. HPFS (primary)
RY> 4. HPFS
RY> 5. FAT
RY> Now, all was well when using OS/2. But when DOS was used, partition 5
RY> became D, but is E under OS/2. So I had to maintain different set of
RY> configs, especially for things such as windows *.ini.
The reason for this is that when you boot OS/2 or MS-DOS, they look at each
partition to see if they can recognise the file system. For each partition
they recognise, they assign the next drive letter. OS/2 recognises both FAT
and HPFS so all the partitions get a drive letter, whereas MS-DOS can't
recognise the HPFS so it just skips it.
Since neither OS/2 or MS-DOS can recognise the Linux file system, both of
them will skip the partition.
I've had all sorts of fun and games in the past trying to keep drive
mapping the same when using HPFS paritions. What you could do to get around
this problem is to define the second HPFS partition as the last partition
on the drive as follows:
1. Boot Manager
2. FAT (primary)
3. HPFS (primary)
4. FAT
5. HPFS
This will always assign the FAT parition as drive D. If you boot OS/2,
you'll then have a drive E available as well. This is similar to the
configuration I ended up with on my computer, except I've got multiple
drives and the HPFS partition is the last partition on the last drive.
