This is a modified version of the M17x R3 BIOS A10, it brings back the SATA behavior of A08 and earlier, while keeping the features of BIOS A10.

A lot of users don't seem very happy with the changes Dell made to the SATA performance of BIOS A09 and up, thus I created this BIOS. Just keep in mind one thing: Dell probably didn't change the corresponding settings in the BIOS for no reason, so it's possible that certain drives may have issue with this BIOS, I don't know.

According to a lot R3 users, A08 brings a clearly better SATA performance on a wide variety of drives. It's up to you to decide what you need and what you want to use. Now you have the choice.

Download link for BIOS A10 with the 'SATA fix', and unlocked hidden menus:

M17x R3 BIOS A10 - unlocked & 'SATA fix'

Read the included READ ME for further information and instructions.

Load the default settings in the BIOS setup after flashing.

It also fixes GPU power throttle if you blind flash from the A04 BIOS 580M method.
