What's the most current M$ BIOS that would work on a 1.5 xbox with a winbond chip. I flashed it successfully with x2.4981, but would like to revert back to retail to play live. The usual places I've checked had quite a few versions, most saying either PAL or 1.6 BIOS. 4817_256k.bin looks promising, but is it compatable with my TSOP?
Thanks to all,
