Asus A7V BIOS Modification

Robert Richmond


Regarded as one of the best SocketA motherboards currently available, the reliable Asus A7V has endured the massive migration of computer users to AMD's new processor format. Whether one owns a Duron 600 or a Thunderbird 1.3 GHz, the A7V has proved to offer both optimum performance and stability.

Modification Procedure


While the base configuration of this motherboard allows for highly optimized system performance, a rather novel BIOS tweak has recently surfaced within the Internet's underground scene. Armed with a couple of small downloads and a DOS boot disk, nearly anyone possessing an average degree of MS-DOS knowledge could benefit with the newly released Asus A7V133 BIOS update.

The A7V133 is an update to the already superb design of the original A7V motherboard. This new board features VIA's recently released KT-133A chipset for support of newer 266MHz bus Athlon processors. Along with the new chipset, Asus has also released a new series of KT-133A optimized BIOS updates. The unique characteristic of this situation is that VIA's technical documentation indicates both the KT-133 and KT-133A chipsets feature the basically the same internal registry offsets. With this concept in mind, one could conclude that the new A7V133 BIOS could be effectively utilized with the original A7V motherboard. After a lengthy period of research, I found myself tempted to flash my A7V with the newer board's BIOS. At least feeling informed but stil hesitant, I decided to actually try out this rather ridiculous sounding idea. Upon flashing the BIOS and rebooting, I expected to witness a blank screen or even worse, possibly a dead system. However, much to my enjoyment, the video card actually posted and the system booted with absolutely no issues to note.
