Even though both Gigabyte and MSI don't include their Slot-A products in their products listing they do have drivers available for download. ASUS, however, doesn't mention anything about their K7M nor provide BIOSs or drivers for it on their main web page. To get a hold of the K7M BIOS and Drivers you need to browse either ftp.asus.com.tw or ftp.asuscom.de and look under their respective PUB directories until you find the SLOT-A area.

ASUS doesn't have a Slot-A section or any information on their K7M motherboard.

Where's the "Slot A Motherboard BIOS Image Files"?

I decided to do a search on ASUS's Web Pages for the "K7M" product to see what would come up.

Unfortunately, absolutely nothing was found!
