Try using flashrom to read the BIOS image. Then you could try using bios_extract to take it apart, and you should get a VSA image. Not redistributable, but should work for you. > So if I would use setpci; i'd be actually changing things within > the VSA; Hmm ... I was hoping I could use setpci to enable the IDE > controller... There's also some firmware interaction there. And if you're unlucky, there's a special limitation in VSA about the controller. > > Drivers that understand GeodeLink directly (such as the X graphics > > driver) do not need the PCI compat stuff. > > Kinda makes sense, as the GPU is built in anyway; what about > Net/Audio devices? Audio is built-in, same situation as for graphics. VSA needed for legacy compatibility, but I believe BSD at least has a native driver for it. > They would have regular PCI connections on the chips so the Geode > would need some form of PCI connector for those devices and connect > that then tot he geodelink? That's basically how it works. A PCI-compatible bus is created with help from the CS553x companion chip. > How about extracting the bios using /dev/iomem + /dev/mem such as > mentioned ont he Obtaining a VGA Bios wiki page? Try flashrom+bios_extract first, ideally it'll also get you the VGA BIOS, which you must have since VESA graphics works. //Peter -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
