a). I can get you a backup of the original OS, but you'll have to re-image the drive using linux on another machine (via a boot floppy or CD ver. of linux).
b's). Or, I can either flash it for you, (you pay shipping both ways, and $15 to get me a Papa John's Pizza, ), ~$40 through Joe (See thread: Bios Chip Replacement for soldered chip), or buy a flashed board from me for $50 shipped.
The linux way (a.) is the cheapest, but will be a bit of an undertaking unless you KNOW Linux. I'm always for money, so if you want the least amount of personal pain, have someone else do it. Many ppl. seemed happy with Joe's work, or pick me. I sure do love pizza.
The "monkey" is on your back now. Let me know if you need my help.
