Tried the disc method, didn't work either. When I originally wrote the chip, I used "load raw" and loaded X-chip v1.2, which worked. Using the same download, I tried again after this problem came up, no good. Downloaded several times and tried each, still no good. I know it's unlikely, but is there a chance that the source file on xbins is corrupted, leading to several bad downloads? Thanks for helping me out on this!
UPDATE: Downloaded my chosen BIOS again, and flashed using "load raw" in X-control. Once again, didn't work. I refuse to believe that this is the chip as EB2K told me it may be. I'm flashing just as I did originally, so I know the method works. I'm lost here.
UPDATE #2: Culprit found! Bad EEPROM somehow, reflashing with my backup now.
