Question: was is it possible to take a boot disk out of a Sparc20 and put it
in an Ultra and run from it - senza modifications.
Answer: No.
Reasons: 1. Architectures are different ( Sparc20 sun4m, while Ultra sun4u)
Going along with that the /dev, /devices, and /usr/platform stuff
would also be different (incompatible)
2. Bootblks are different. Sparc20's also boot from scsi id 3, while
Ultra's boot from scsi id 0.
3. The disks have different physical mounting hardware
