epia m vga + memcpy failed - coreboot

6 Sep 2004


      I was trying to figure why VGA wasn't being properly set on my epia m
when I found that the code in mainboard.c was looking for device id 0x3123
while my epia m has device id 0x3122 for the CLE266.  After changing
the id, memcpy is failing to copy the bios code.  Anyone know why that
could be?  Here's a piece of the log:
