I would like to split a 30GB IDE drive into 4 or so

I don't know much about SCSI really, but I believe that it is possible
to divide some drives into individually addressable logical drives,
sort of like partitions, but at the hardware level.
The SCSI bridge could do this.
As already mentioned some RAID arrays
split an array into multiple volumes and present each volume to the
host as a LUN. It should be no problem doing this with a single disk.
But the controler must support this and most likely the ACARD doesn't.
I am trying to compare different versions of NetBSD.
You can do this: Make a sd0a partition that holds your primary
instalation and the kernels of your different other versions. Make a
partition for each additional version you wane test, e.g. sd0d,
sd0e, ... and hardcode these as root-partition in your individual
kernels:
config netbsd root on sd0e type ffs
This way you can have multiple parallel instalations, each in a
separate partition. Boot selection is done by chosing a different
kernel to boot on the boot prompt.
