turns out that the boot PROMS are NOT compatible. swapping them
didn't hurt anything, but gave me two systems that wouldn't boot.
however, it is possible to boot off the net and then switch to the
Ciprico. the kernel config file has to have the line
config vmunix root on rf0a swap on type spec rf0b
where rf0 is the disk attached to the ciprico controller, AND
swapgeneric.c has to be slightly modified to find that controller.
thanks to
for actually figuring all this out and sending me the mods.
