I wandered past an old Compaq EISA system and decided to try the
1.5 boot.fs on it. I booted it up, but, it only detected 16MB out of the
32MB on the motherboard (should they be interleaved?). Then when I tried
to mount the floppy disk to write a dmesg, it paniced the system.

Dmesg copied by hand:

	Any operations relating the fd seem to cause a panic, but I have
only looked at it in passing.
