This board has absolutely no option for AHCI in the BIOS, confirmed by examining with AMIBCP 3.46. MMTool shows no OROM either.
This one is a challenge. Board is ICH8 so it definitely supports AHCI, and I'm pretty sure all other varieties of P5B do as well.
If anyone is up to the challenge, here's a link to the BIOS:

If you need me to run something on the board, just ask. Thanks.
