Yes, in fact there is no internal video card in my board, so i am using a external PCI card, Matrox MGA millenium. I will try with VGA bios from original Tyan bios.

Thank's for the advice, i will remember for next time.

Coreboot is 32 bit, but it will work fine with a 64-bit OS.

Most of it is empty space.  When the ELF gets unpacked, it doesn't take that
much space.

Have you tried using a separate graphics card?  That would narrow down the
problem.  I would try adding the VGA BIOS, though.

I thought if you did a 'make clean' it deleted the .xcompile file.

I would add a Video card or put the VGA BIOS into coreboot.rom.  Whichever
one you find easier.
