Hello, I have no clue where to ask this question, or if I can request a modification of my BIOS.
I have a ASUS Rampage III Extreme with a USB 3.0 Renesas uPD720200F1 chipset on board (PCIe x1 chip with 2 USB 3.0 ports). This exact chipset on every other board on Earth allows you to boot using USB 3.0 devices, such as the SanDisk Extreme's etc. However my BIOS refuses to see USB 3.0 devices on the Renesas USB 3.0 chipset. I can only boot to USB 2.0 devices on the USB 3.0 ports (WTF?). Further, in Windows the Renesas USB 3.0 chip is getting me 255 MB/s reads and 130 MB/s writes, so I know for fact the chip and USB 3.0 ports are OK.
So, I have to assume Asus forgot to include some code in my BIOS that allows the BIOS to boot to USB 3.0 bootable devices. ALL 100% of other Motherboards with my EXACT chipset boots USB 3.0 devices just fine. Why doesn't mine? My buddies Gigabyte x58 UD3 with the same chip boots all of his SanDisk Extreme's, but I can't see a single USB 3.0 device no matter what brand or model it is. I have to put all my USB 3.0 devices on USB 2.0 ports just to use them in the BIOS for booting, which completely defeats the purpose for me. So I really need help to figure this out. I have tried EVERYTHING imaginable in regards to BIOS USB settings, but the symptom is the same.
Where in these forums can I ask for help with my AMI BIOS to see if USB 3.0 Booting is unlockable, or even possible on the R3E? I just want to see my USB 3.0 bootable devices after hitting the F8 key.
Please Help if you think you know what is happening and if its fixable. Thank you very much.
Best Regards
Rod
P.S. I have all the BIOS's for my board, modded ones from here and unmodded ones.
