Need some help, plz.

Hrmm, ok, here's the issue. Using a Xenium chip, have Slayers Evox on cd-rw. I don't have a bios on disk, i'm not even sure where to get one. The real problem is this:

I unknowingly unlocked my HDD without fixing my xeniumOS first. I got the panic Kernel, and was able to get into the xenOS by eject button means. I try to get back into disk tools, but I keep getting the kernel. I'm afraid I've corrupted the OS. Is there any way I can fix it, or maybe take it back to it's default values? Or maybe install another Bios and go in from there? I'm really lost, and extremely frustrated. =\ Thanks much...
