Even the PCI SunGEM cards have the FORTH firmware stuff in their PCI ROMs. The FORTH firmware on the Sun or MAC machine, at boot time, looks for the FORTH signature in the PCI ROMs of all the devices in the machine, and executes whatever matches it finds. The SunGEM PCI card variants have this firmware, just like the motherboard variants do.
I don't think a SunGEM chipset card or motherboard implementation ever existed without the necessary FORTH firmware in the PCI ROM. And, certainly, no SunGEM was ever made with accompanying x86 style firmware in the PCI ROM.
Hmmm... actually, I think I have a dual-function PCI card somewhere that has a SunGEM and a Qlogic scsi controller. If I can dig it up I'll stick it into one of my x86 boxes and play with your patch :-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
