[SunRescue] Sparc10 with no 3,0.

i don't know what your problem is exactly, but it sounds like a bad disk. in 
any case, it is not a confusion between your default boot device and the 
framebuffer. the 3,0 is referring to sd at 3,0 which means "scsi disk" @ target 
3 (scsi id) lun 0. the 2,0 you see for your framebuffer is probably 
referring to the sbus slot number. each field in the hardware path is 
significant. the hard drive you have installed is sd at 0,0 or scsi id 0. at 
the obp prompt type:

ok boot 
/iommu at f,e0000000/sbus at f,e0001000/espdma at f,400000/esp at f,800000/sd at 0,0

if that works, you can create a device alias for it and reset your 
boot-device variable so that it will automatically boot up.

e.g.:

ok nvalias disk 
/iommu at f,e0000000/sbus at f,e0001000/espdma at f,400000/esp at f,800000/sd at 0,0

ok setenv boot-device disk

anyway, you can always try to boot into single user mode from a cdrom drive 
and try to mount the hard disk and see what is going on if that doesn't 
work.
