Hm, right. Yes, floppy is now detected:

fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> at port
0x3f7,0x3f0-0x3f5 irq 6 drq 2 on isa0
fdc0: interrupting at ISA irq 6
fdc0: FIFO enabled, 8 bytes threshold
fd0: <1440-KB 3.5" drive> on fdc0 drive 0

But the long standing bug is still there:

ds10#fdformat fd0
Format 1440K floppy `/dev/fd0'? (y/n): y
Processing EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE done.
Errors encountered:

(Further errors not printed.)
