Yes, this too has been my experience with IDE drives.  When using SCSI   
(BIOS) or a SCSI/IDE mix, I'm not sure what the standard behavior is.

In my experience it has been

        - primary DOS partition on each drive, in order of drive #
          (in the case of a drive with TWO primary partitions, like
           i've done on my win95/dos disk, they're done in order of
           which is marked as startable first [i use os-bs 2.0b8 to
           boot win95 or dos on a disk with a 10M dos partition and
           a 235M win95 partition; i selected the "set start ID on
           bootup option or whatever it is in OSBS, so if i boot to
           DOS only, the 10M is C: and the 235M is D:, but if I boot
           to win95, its the other way around, because OSBS changes
           the 'startable' flag])

        - extended dos drive in each extended partition in order

Thus for example:

                You have                        Becomes
                --------                        -------
  Drive 0:      Primary DOS partition             C:
                Extended partition
                        extended dos drive        E:
                        extended dos drive        F:

  Drive 1:      Primary DOS partition             D:
                Extended partition
                        extended dos drive        G:


I hope
        - this makes sense
        - this is correct.

Someone correct me if I'm wrong .. this has been my experience.

Cheers,
Phil
