Flavio and Michael, thanks for the info. This is good. I have a
feeling my machine is going to give me a few problems trying to use 2
disks on the same controller, but I'll try that again later.
I'm really focused on trying to get the thing to be able to boot from
the hard drive by only using stuff available from the install CD.
The stuff that Uwe said earlier (which I remember from a long time
ago) makes it seem like it should be possible, after all, all they are
doing is putting an iso filesystem on the front of the disk and then
loading the bootloader from there. If OpenBSD can create an MSDOS
filesystem at the front of the disk and load a bootloader from it, and
then have it load the kernel from the / disk, we should be able to do
it too. Also, they are using the mkisofs command, and I think this has
been gone for a while and I don't remember which tool replaced it,
I've been trying various stuff and the firmware seems to be very picky
about it so far, but I'm not done yet. I'm probably missing something
really simple between fdisk and disklabel when at the # prompt in the
installer CD. So far I'm not able to get disklabel to label the disk
after I do fdisk to create the MSDOS partition (id 6) and the NetBSD
partition (id 169). It complains about some stuff.
