It does try to boot, but gets to the Bios screen and sort of hangs up. Now, this had been "operating" without a hard drive, and I'm wondering if it had been set to boot from the CD drive, but I don't know how to check that, or re-set it if that is the case.
The Bios screen is at least recognizing the hard drive, which I guess is a good thing. I just wish I could get it to go ahead and boot from it!
I guess I'm going to run it up to the "neighborhood computer place" which suggested my eBay efforts in the first place. Maybe they can coax this into working.
