I'm working with a Sun Microsystems Ultra 10 and want to wipe the contents of it's hard drive. I have a Rescue CD with DBAN on it but the computer won't boot to it. Why not? Can I make it? I'm completely unfamiliar with this, all computers have a BIOS right? So in theory I could tell it to boot from the CD-ROM.
DBAN looks to be designed for x86 computers using a BIOS.
An Ultra 10 is neither of these, being an UltraSPARC computer using OpenBOOT.
You need a Solaris bootable media (commonly a CD) to wipe your disk.
