I have a SunFire 280R here (2GB RAM, 1 CPU installed, second is still
boxed), and to see if the Sun (Symbios Logic) PCI SCSI card works, I
hooked up a disk that has NetBSD/sparc64 installed, which ran on an U10
last. Here's how far it got:

ok boot /pci@8,600000/scsi@1/disk@4,0

I'll have to setup the machine w/ Solaris soon, but I guess i can wait a
day more or three, to play with NetBSD on it. I guess first step will be 
to do netboot, or is there another way to boot a newer kernel? Can I write
it to the (NetBSD-formatted) disk from Solaris? (ISTR some way it shredded
disks...)
