The most likely cause of this is a bug in our partition-generating
script which can cause it to use the wrong geometry on large IDE or
SCSI disks which use translated geometries. (Yes, this is a pretty
serious problem; hopefully I'll find time to address it soon.)
I think the best thing to do is to get "pfdisk" and put it on a
floppy. Boot off the floppy and run "pfdisk 0" (or 1 if it's your
second disk). Use "L" to look at your disk's partition table, and
then recreate the NetBSD partition table without changing anything.
e.g. if "L" says your NetBSD partition table is partition number 2,
with system ID 165, starting at cylinder 236 and ending at cylinder
497, you'd type:
2 165 236 497
Then use "w" and "q" to write the partition table and quit. pfdisk
will recreate the partition table using the correct (translated)
geometry, so that booteasy and osbs can boot it.
Sorry for the inconvenience.
