UH, I may have messed something up: I can get it to boot NetBSD, but not LINUX.
If I press F4 NetBSD boots -- but if I press either F5/F6 the screen prints "LI   "
and hangs.

When I installed LINUX, I disconnected the NetBSD disk, made second disk the
master, installed LINUX in it, and rejumpered it as a "slave" disk.
I then recabled it in the original manner. If I do 
"/sbin/mount_ext2fs /dev/wd1a /mnt" I get : "Device is not configured"
