> === PCI new allocation pass #1 === > PCI: check devices bus 0 Hmm, with 512 MB seabios should have paniced here with: PCI: out of address space > PCI: map device bus 0, bfd 0x28 > bar 0, addr febe0000, size 10000 [mem] > bar 1, addr 0, size 20000000 [mem] Somehow seabios didn't recognise the bar correctly it seems (both 512 and 256 MB cases look the same). For the 256 MB case seabios should have mapped the bar @ 0xe0000000. cheers, Gerd
