Hi
Had this problem too. Flashed the card to 1.03.27 and it disaperad in Mac OS after this. Asked LSI and Apple for a firmware. One of the LSI Technicians found it on the net. Cool guy. Flashed this ROM and voila, back in business. The card will be recognized by MacOS again. Did not tested in production yet, but everything looks ok.
The Firmware version is 1.03.24 which does not match the versions on Apple HT1769 KB article, but it works. What I further have to say, that I didn't flashed the Bios. My card has an EFI 1.05.06 Bios.
I put the .zip on this link hoping some other people can restore their wrongly flashed cards. If one day the file isn't there anymore, just leave a reply. I will keep the file in save place (probably not on a raid attached by this card đ).
Regards
