I don't know what the problem is, I don't have an EPIA-M yet. ... Are your sure the clock source for the superio or uart is the same for linuxbios and award?
The "emulator for VGA bios" will actually run anything...
If sending you an epia-m would mean you'd begin looking at it I'll get you one. Let me know.
I'm not sure of the clock source, VIA hasn't provided a schematic for the board. The datasheet indicates 2 clock sources, one is for the LPC interface and the other is for the main clock. LPC is the 33 mhz pci clock. The other clock is 48 mhz. I had a scope on the chip and as near as I can tell the 48 mhz clock was in fact 48 mhz. I didn't look at the 33 mhz clock at all.
