Not really an outline; it is just one MSR read. Take a look at the GPIO kernel driver: http://lxr.linux.no/#linux+v2.6.31/drivers/char/cs5535_gpio.c#L188 Also, to correct the 0xF0000 scan ickiness, the proper way to detect a board revision is usually done by reading a PCI subvendor/subdevice ID too. I don't know if alix's non-coreboot BIOS does that properly. -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
