true, but YABEL still has to copy it, after all the code runs from copy... can we modify coreboot to not copy the image from ROM if YABEL is selected, but pass the location of the image in ROM to YABEL? ... >> Currently, the ROM is always copied from the Expansion ROM bar of PCI >> devices.... i havent had to initialize any onboard devices.

Ok, i will try to implement that and send patches. Cheers, Patty -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
