On my search for a LinuxBIOS compatible AMD mainboard, I tripped over the ECS 760GX-M. It's socket 754 and uses the SiS chips 760GX and 964. As far as I know SiS is supporting LinuxBIOS actively, so in terms of the chipset the board should run LinuxBIOS. Plus, it has a 4Mb (=500 KiB) Flash ROM with the following description from the manufactorer's website:
Award BIOS with 4Mb Flash ROM
Supports Plug and Play 1.0A, APM 1.2, Multi Boot, DMI
Supports ACPI revision 1.0 specification
Because I want to be shure that this mainboard supports LinuxBIOS before I will buy it, I thought I'd better ask here if anyone has it in use and can say something about it. The chipset and the plug and play BIOS at least sound promisingly to me. Oh, and a previous ECS mainboard, the K7SEM, is proven to be compatible.
