In /dev/bios I've been using the following code to switch between the
ram image and the rom image. I don't have the specs at hand, but you
should look into the specs of device 0x1078:0x0100
static void cs5530_activate(void)
{
/* Save modified registers for later reset */
pci_dummy[0]=pci_read(CURRENT,0x52);
/* enable rom write access */
pci_write(CURRENT, 0x52, pci_dummy[0]|0x06);
}
static void cs5530_deactivate(void)
{
pci_write(CURRENT, 0x52, pci_dummy[0]);
}
