Illegal instruction "0xhex" was encountered at PC 0xhex

Cause

The machine is trying to boot from a non-boot device, or from a boot device for a different hardware architecture.

Action

If you are booting from the net, check Readme files to make sure you are using a boot image for that architecture. If you are booting from disk, make sure the system is looking at the right disk, which is usually SCSI target 3. If these solutions fail, connect a CD drive to the system and boot from CD-ROM.
