has this ever been confirmed to work? flashing Sil3124 with 2SE4 firmtek firmware?
theres a number of silicon image pb3124 cards being blown out on ebay atm, can get 2 of them for under 40$ and they come with bios sockets + MX large flash eeproms (the same brand of chip was good for flashing the sil3112's?)
Shipping to my location is (always) too expensive to try.
If you have a PC, you can try flashing it with the SeriTek firmware. And if that doesn't work, you still can re-flash it with the original firmware and use it as a non-bootable SATA-2 card by installing Silicon Image's Mac driver.
