I bought a few cards as well and couldn't wait to give these a try.

I flashed the SeriTek/1s2 v5.13 firmware to one card using the DOS utility

It returned the 0 code, which means successfull flashing.

I then installed that card in my QuickSilver.

The QS boots* but...

The flashed card is listed as a SCSI controller with the name "Athena_3112" but as you can see below, no driver is loaded.



For comparison, here's how system profiler shows an unflashed card:



*(it won't boot with a flashed Sil3512 variant)
