X79 UD7 can't launch QFlash, stuck in net boot
« on: September 19, 2017, 05:10:02 pm »
Hi !

I have a X79 UD7 firmware F10 that used to work fine.
I tried some OC by changing the ram speed which didn't work (reboot loop),
which lead to a bad bios and the backup bios to be copied.
The now installed firmware is F12f

Now the pc only boots through intel boot agent to net boot.
The USB ports aren't working so I have to use a PS2 keyboard...

The only BIOS screen I can enter is the Port Configuration Menu.

When I hit F8 to enter qFlash, it starts to show, then fades away.
When I hit END during POST, nothing happens, or I see something starting to show then fade away.
Entering DEL during POST sends me to the same net BIOS.
Other F keys don't do much else :(

I tried resetting the CMOS with the reset button, and by removing the CMOS battery 15 minutes (PSU unplugged).
Swapping BIOS...

I'm stuck with this net boot bios, which doesn't start the USB ports, and won't let me change anything.

Any hint on what else I could do to reflash an older or different firmware, or how to get out of netboot would be greatly appreciated :)

Thanks !
