Yeah, I tried using f13ht when I installed my second floppy drive, and had no
luck.  Then I discovered pg 104 of the 386/ix opserating sytem guide:

f1q18dt - minor number 81 1.44 MB,entire 3.5 disk
f1q18d  - minor number 85 1.44 MB,omit boot track.

subtract one from the above minor numbers to use as drive 0.

Of course, if the special device files don't exist you'll have to
use mknod to create them in both /dev/rdsk and /dev/dsk as char and block
devices respectively.

Now here's a question for the netlanders:

I'm thinking of swapping my two drives, to make the 1.44 meg (in dos language)
a:, and my 1.2 meg drive b:.  Does anyone know how I can create a bootable
1.44 meg 386/ix floppy from my 1.2 meg distibution floppy?  I tried dd
unsuccessfully, but I could have specified some parameters incorrectly.
