I have an ASUS A7S333 motherboard that seems to work great so far (I have two socket 462 processors for it), and am planning to use it in a system to properly play some Win9x games (Half-Life, Quake III, Unreal, etc.) instead of using time-accurate hardware and suffering with the terrible performance that unavoidably comes with such hardware configurations- I've been working on a time-accurate Slot 1 build to run these games well for years.

Anyways, I have an Athlon XP 1800+ (Palomino) and an Athlon XP 2600+ (Thoroughbred, 266 MT/s). I'm wanting to put the 2600+ in there, but in order for it to get above 1800MHz (the 2600+ runs at 2133MHz), and to get the system to recognize the CPU properly, I have to flash a newer BIOS. Normally, motherboard manufacturers package the flashing tool in with their BIOS, but not in this case- instead, they left me to have to find it myself. Here are the links I've been using for both the BIOS and flashing tools:

BIOS: https://www.asus.com/supportonly/A7S333/HelpDesk_Download/
AWDFLASH: https://www.wimsbios.com/awardflasher.jsp

The issue here is that the latest version of AWDFLASH says that the BIOS images are the wrong kind- they're not. I have the SiS 795 chipset if there's a possibility of two of these kinds of motherboards existing, which I doubt, but it is possible. I have tried 8.99, which says it's incorrect, 8.65 says "please wait," but freezes on that, 8.30 says that the ROM on my motherboard isn't updated enough (???), and 8.00 freezes and says nothing. 7.xx and below seem to be a fair bit older than this motherboard, so I doubt the BIOS chip in use here is supported.

Any help is greatly appreciated, I've tried this using both the 2600+ and the 1800+.
