Do DR DOS-FDISK'd drives support MS DOS software?
My laptop's 1gig DR DOS 7.02 FDISK'd hdd (particulars
at the end of this msg) has a 4meg pre-DOS partition
for Compaq setup and diagnostic firmware, and at the end
a 386meg unused non-DOS partition for maybe-someday linux.
In between are DOS logical drives C: to H:.
The drive has been troublefree till now. What's new
is that MS DOS has joined the mix.
The setup/diags firmware I had was the wrong release
for my system and I let that ride till I decided last week
that I must install the win95 that has long sat unused
in cab files on my hdd, expecting to dualboot DR DOS
(my OS ever since DRI released DR DOS 5).
First I called Compaq and got the right setup and diagnostic
firmware. I find that when invoked it self-boots under
MS DOS 6 and when diags access drive C: they trash the
partition. Would you believe, one 4.3 *billion*-byte file?
After reformatting the partition I tested the win95
install bootup floppy with an AUTOEXEC.BAT that stops
just short of starting setup. To my dismay, an MS DOS
dir command too shows a scrambled C:. Interestingly,
if I, e.g., set c:\swap as tmp the drive stays scrambled
but if I reboot with DR DOS without doing anything to C:
under MS DOS the drive is OK.
Help? ... Ciao. --Fisher
