Seems to be SER523 / Intel SRCS16 6-port RAID controller - just like the 
one I played with a month ago.

I tested it in two machines, one IBM x232 with 64-bit PCI and one 
regular PC with D815EEA2(?) mainboard with 32-bit PCI. I had no trouble 
with the 32-bit system, the BIOS worked and the card was found by Linux 
megaraid driver IIRC. I had some trouble in the IBM x232 - BIOS detected 
the card but when I pressed the key combo for setup, it told it will be 
entering setup when POST is finised and then didn't - just like Adapatec 
2610SA card in the same machine.

But this specific card worked fine on 32-bit PCI.

Beware that this beast has drive size limits - it's about 500G or 750G 
SATA. I tried 1T and it was not detected correctly and did not work. 
Then I found the docs at Intel site telling that this was a documented
