is apollo 400 non-i386 arch? possibly disklabel are in different format.
try attaching to x86 machine

or

dd if=/dev/rsd<something>d of=save bs=4k count=1 (to save header)

disklabel -I -i sd<something>

create first partition a beginning from 0 to end of disk.

then use dumpfs to check size of filesystem

then reedit disklabel (disklabel -i sd<something>)
reeding a partition to match size, make e partition just after a to the
end of disk, save and repeat dumpfs step, then (if it's still ffs) reedit
disklabel etc....


should work if partitions were made without any tricks
