Just brought a dirt cheap sil3112 card (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180796383734) my plan is to try and put a bigger (2mbit or bigger) chip on the card, my only worry is weather the card will work without a firmware on the chip? since i have no external programmer i need to program it in place (or possibly if the chips are compatible with those on a old dual bios gigabit board i have solder the chip on there and hope the bios flasher on there has no integrity checks)
