BIOS Update Failure on GA-MA790FXT-UD5P

[illogical]

Oh dear I wish I had read this first, http://forum.giga-byte.co.uk/index.php/topic,2441.0.html  just updated my GA-MA790FXT-UD5P using @bios, machine reboots, makes a nice single beep then nothing, just the splash screen ad infinitum.
So far tried, removing power from PSU-(takes about 90 seconds for all power to dissapate), pressing the CLR CMOS button for 30 seconds.- no change.
Tried getting into QFlash all I get is a black screen with a little purple/blue character in the top left corner of the screen.
Pressing F12, gets me an after post fail message and option to load default or profile 1, neither of these 2 options achieve anything.

Right now I've removed all drives all adaptors except the graphics card, detached all USB devices and plugged the FAT32 formated USB stick in the rear to USB port, pressed END and am sitting posting this message with the little purple sort of running man graphic in the top left corner.

I'm considering swapping the 2 BIOS chips about, but as yet haven't checked to see if they are socketed.
Any flashes-( ) of inspiration much appreciated.

I'm suspecting this is time to sit my new Phenom 1090T on a new board, maybe one which will allow my OCZ RAM to run at it's rated speed of 1800MHZ.

Hi and welcome to the Gigabyte Forum.
Sounds like you have some problems. First thing is to unplug and then remove the battery from the motherboard for at least 10 minutes before replacing and loading optimised BIOS settings.
Post again when you have done this.

You can forget runnning your memory at 1800 speed anyway as the controller on the CPU wouldn't be able to stand it.

[illogical]

Thanks for the quick reply, right now I have to go collect my grandson from Nursery, so I'll remove the battery and PSU cord until I get back, probably about 1 - 2 hours, so plenty for all to be clean.
BTW the RAM has been running @1600 with a Phenom 955BE since I bought the board, that combination would not tollerate raising the FSB by more than 5, the 1090T will let me run the RAM @1800 by increasing the FSB but it drags all the other busses too high anyhow that's not important for now.
Will post again later.

OK been left unpowered without the battery for over an hour and it's still no change from the origional scenario I posted, with the addition of trying to use del resulted in a cmos checksum error loading defaults, I accepted that, it rebooted posted but once again stops at the splash screen.

OK,

The reality is that swapping the BIOS chips isn't very practicable as they are soldered into place.

You can try to kick in the backup BIOS by shutting down the PSU from the wall, then hold down your case power button in and then turn on the power supply button, a few seconds later the board will start, shut off the power supply then.   Then you can turn on the power supply again and power up the board normally and DualBIOS will kick in.

  Job done all I need to do now is update the BIOS to a current version, Q Flash is only listing floppy A & B as sources, I have no floppy disc, the usb drive is inserted in the outer uppermost USB port, formated FAT32, so I'm either going to need to install a floppy drive and copy the BIOS to that or risk @BIOS again.
Rock and a hard place EH ?

Your USB stick could be recognised as a Floppy Drive.

Have you checked what is on Floppy A or B?

If you have disabled the Floppy Drives in BIOS then your USB Stick could show up as an HDD.

[illogical]

You're guessing correctly I have floppy disabled and it's controller, how do I get Q Flash to scan for other than Floppy drives ?

[absic]

Did you make sure that your USB stick is plugged in before you started your PC? If not it won't be recognised correctly.

I can't say exactly how it will show up in QFlash as I'm not running your Mobo but on mine it comes up as HDD 0-0 <DRIVE>

[Dark Mantis]

Insert USB pendrive and then go into the BIOS and enable Legacy USB devices and Legacy USB Storage then go to the boot section and set the primary boot drive as USB HDD


See you just beat me there absic but using pictures is cheating

[absic]

It's not cheating at all and you're only jealous because I have got a camera!

[illogical]

Thanks everyone for your time on this, I'm now running fine with the latest F8l BIOS and all is well.

[Dark Mantis]

While you are there you might want to sync your BIOS versions also. You can do this by pressing ALT + F12 when booting


and all managed without a camera

[absic]

This is true but you forgot to mention the fact that syncing BIOS using ALT+F12 is more successful if you use a PS2 Keyboard rather than a USB one.
The same goes for any activities in BIOS that you are doing, actually. 

[Dark Mantis]

Quite right (unless you have the magic touch)
