Besides that, there are still unexplained differences between vendor BIOS and LinuxBIOS in the PCI configuration. http://linuxbios.org/pipermail/linuxbios/2007-May/021538.html and the followup http://linuxbios.org/pipermail/linuxbios/2007-June/022299.html Oh, and here is a nice dmesg diff snippet: --- dmesg.vendor 2007-10-27 03:11:10.000000000 +0200 +++ dmesg.LB 2007-10-27 03:11:10.000000000 +0200 PCI: Bridge: 0000:00:06.0 IO window: disabled. - MEM window: fb000000-fb0fffff + MEM window: disabled.
