SCSI Status Error

[Avalir]

Hello,
I'm attempting to install GhostBSD on another PC and I'm encountering an error.
It lists as:

Is it saying my optical drive is bad?

It seems I misinterpreted the error.
The drive is fine; I noticed the BIOS present a message that some settings would have to be modified for use with Unix.
It is an HP DC5800; I've never heard of changing parameters to use other operating systems.

What would I have to change?
