Okay, I've got three separate problems today:
Doscmd is really only useable with X, and running doscmd -bx with a local X
server generates tons of "trap 25 with interrupts disabled". I don't recall
this being the case many moons ago...
When I mount a floppy image (msdos, using the vn device), I soon get:
panic: zone: entry not free
syncing disks... 152 47 44 38 31 24 17 1 done
dumping to dev 30001, offset 73728
dump 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1

I'll try do some more testing on this... I really don't know if it's a problem
with msdosfs or vn. It will only show p (like this) with INVARIANTS on.
I also notice I can't seem to use my flopy drive anymore. The BIOS and BTX
can both use it, the kernel:
fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa
fdc0: FIFO enabled, 8 bytes threshold
fd0: 1.44MB 3.5in
fd0: 1.44MB 3.5in
and I can hear the drive click-whir-buzz like normal, but if I try to use
the drive ({,r}fd0, etc), all I get is
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 70<abnrml,seek_cmplt,equ_chck> cyl 0
fd0: recal failed ST0 78<abnrml,seek_cmplt,equ_chck,drive_notrdy> cyl 0
fd0c: hard error reading fsbn 0 of 0-3 (No status)
With this, I'm wondering if everyone's floppy drives work fine and if their
drives work fine on an AcerLabs socket 7 motherboard. If so, maybe I can
scrounge up a different floppy drive and try it out, but it really seems
to not be a hardware problem.
Thanks in advance.
