Bios Mods -The Best BIOS Update and Modification Source

Have 1 Intel SSD 120Gb, 1 WD 1Tb black and 1 WD 3Tb Black.

Problem is that, no matter which disk I connect (only one or all of them), system keeps rebooting if bios setting is in AHCI. Starts normal only in IDE mode.

Something that can be resolved with bios modding ?

Update: Have seen now, BIOS recognizes 3TB drive as 800Gb (Win7 can see whole disk). Does it have to do with problem?
