Looking for BIOS for SATA2000 Controller

Hi all,

I bought a SATA2000 controller card from SUNIX with 3112A chip. It
runs without problems, but after I flashed the BIOS with a new version
from Silicon Image my PC hangs on startup just when the card
initialized itself and the hardrive although the card bios gets no
error.

When I plugin the cable into the hd during running system (w2k) my OS
recognize the drive and I can work with it. Maybe there is something
wrong with the new BIOS version. I send some requests to Silicon Image
and Sunix to get the BIOS version which was installed first, but I got
no response.

So, is there anybody who can help me? I'm looking for the old BIOS
version 4.1.34 and I hope that is the reason why.

thanks

Michael
