Flashing Silicon Image SIL3512 IDE BIOS
The Silicon Image 3512 is a PCI SATA controller that is commonly used in older systems. By default it comes with a RAID BIOS that supports RAID 0 and RAID 1. Flashing it to the BIOS below converts it into a normal SATA controller without RAID support. If you have no plans to use RAID, this is probably a good idea.
If you are using Windows, make sure you install the SATALink drivers before flashing. You will need to boot into DOS (FreeDOS works too) and run this command to flash the BIOS:
Choose option #2. If it errors out it should still be fine, and on reboot it should say SATALink in the BIOS description with no options to configure RAID.
