I found an 9122 dual 3.5'' flopyy drive lying around and I connected
it to my 9000/350 workstation. For the record, the HPIB board select 
code is 0x07 and the drive is on HPIB address 0x06, so the two floopy
drives are accessible as major device 4, minor device 0x070600 and 0x070610
respectivel (I found all that by trial-and-error; no documentation around).

At any rate, can I use that baby to read and write diskettes written
from IBM PCs and PS/2s? I tried reading a PS/2 1.44M diskette and I
got I/O errors. I tried mediainit-ing a new floppy, and all I can get
is 77 cylinders (rather than 40 or 80). Is there a utility or a drive
(or even a different minor device number) that I can use to access it
as a DOS floppy?

Thanks,

PS: No, I don't want to write DOS disks, I want to write 386/ix disks,
so there!
