I have a dell vostro 1520 laptop. it keeps losing an important bios setting (the AHCI/ATA compatibility). It keeps switching back to AHCI after I set it to ATA. It won't boot if it's set to AHCI and I have to manually change it to ATA mode as it loses the setting.
Any idea how i can make it retain the settings?
I installed a new hard drive and loaded a fresh copy of XP. Everything works normally after setting it to ATA mode and restarting it.
