In the Bios in integrated menu I see with * Hou min PCI TO PCI BRIDGE. Any sages ??????? CTRL+M is not sow in start menu . ????????

Try reseating the entire riser board. Also reseat the RAID battery, memory, and key.

I OL REDY DONE BAT THE BROBLEM IS THE SAME >

Then you need to replace the riser (probably) or motherboard.

Your spelling makes your posts almost impossible to read or understand.

I pout the kit in a new 2850 and is work ok pat I can not upgrades to 522 . win 2008 or bout cd cdu-1,6 . the cdu cd wen I go to upgrades hi ask a different cd with driver . win 2008 is not find the correct hardwer

sorry for the language is not my best

You might be betterminated off using Google Translate from your native language ... I really am not sure what you are seeing right now. 522?! If it says you need  CD/DVD driver, then your Windows media is bad.

I try to make upgrades the RAID FW from 518 to 522 but not accept from win 2008 . I try also with dell cd named cdu-1.6 bat wen I go to the upgrate paragraph is start and after a some sec hi asks my a different CD with drivers .
