Jochen,
Your instructions worked perfectly. I'm now booting off the floppy
via a menu. Thank you!
Now if I wanted to boot from the HD, here's what geometry reports...
Drive 0x80: C/H/S = 1078/243/63, The number of sectors = 16514064 /dev/rwd0
Partition num:0, [BSD sub-partitions immediately follow]
BSD Partition num: 'a', Filesystem is ffs, partition type 0xa5
BSD Partition num: 'b', Filesystem is unknown, partition type 0xa5
BSD Partition num: 'e', Filesystem is ffs, partition type 0xa5
BSD Partition num: 'f', Filesystem is ffs, partition type 0xa5
If this helps, here's a dump from disklabel...
