BIOS Flashing - A "How To ~ Qflash Guide"

[Lsdmeasap]

Well Bootable USB is not needed with Qflash, at all. Just enter Qflash using the END key at boot or the F8 key while on the MAIN page of the BIOS.

Then all you need it the .Fxx file on a USB, nothing else is needed. And the USB does not need to be a bootable USB, just formatted FAT32/16 or 12

owh ok.i understand now. i'll post again after done updating my BIOS.

K, Good luck!

Ya, the bootable USB method was only posted for those who cannot get a USB stick to be found in Qflash for some reason. Most of the time it was just because they forgot to leave the USB stick in when rebooting to Qflash, or did not format the USB stick, Or Did not look thru all "Disks/HDD/Drives" shown to them by Qflash, or Did not have Legacy USB Storage Detect Enabled in the Integrated Peripherals Page.

If you formatted your USB Stick to FAT32, then all you need to do is add the .Fxx file onto it, leave it in and reboot to Qflash. Then look at all the Options it shows you as places to open and look for a BIOS file. I often see HDD for my USB sticks, as shown on page one

Hi,

Now that you have the EP45-DS4P ... its online manual shows
CLR_CMOS jumper and CMOS_SW switch side-by-side
but only explains the use of CLR_CMOS (and so does this thread).

Is the CMOS_SW just a marketing thing, or could one actually use it?

[Lsdmeasap]

Yes, you can use it. I am not sure how long you have to hold it in, but I tested it the day I installed when I was flashing My BIOS and it seemed to clear it just fine. I held it down for about 10 seconds I think. With the board plugged in of course

The jumper method will still apply as well, but seems the switch works. Not sure how that will be when a Clear CMOS is for sure needed because of actual problems though?

As in:
1. Shut down your System, and let it rest for 30 seconds to a minute.
2. Unplug the Power Supply from the wall.
3. Press CMOS_SW for [unspecified] time.
4. Replug PSU.
5. Load Optimized Defaults
6. Restore customized values (like RAID mode).
7. pray
???

(I don't want to err on "obvious" details.)

No, As is this is what I did >>>
1. Shut down your System, and let it rest for 30 seconds to a minute.
2. Press CMOS_SW for 10-15 seconds.
3. Restarted PC to see if CMOS was cleared, it was.
4. Flashed New BIOS.
4. Load Optimized Defaults.
6. Restore customized values (like RAID mode).

You will be fine for sure, it is a nice feature. I wish the would have documented it a bit more then just the image and description they did in the BIOS though. Like how long it must be held in would have been nice.

I do know you can use it without the power plugged in as well, I just tested with it plugged in to see how it worked

[mv2devnull]

Thanks. Did work, I presume (writing this am I).

[Lsdmeasap]

HAHA

Ya, It is a nice feature! Especially when you are working out of the case!

I am glad they added it, adds to the overall looks and quality of the board as well

Not sure if I should post here or start new thread, but here goes...

I cannot for the life of me flash any BIOS version other than F3 to my board. I have a GA-EP35C-DS3R (see sig), and use a usb thumbdrive and QFlash to do the flashing.

I was wanting to try the F4a, but every time I try to load it, I get the "BIOS ID Check error." I have tried flashing F2 just to see if I could, and it does not work, either.

I have also tried loading the BIOS from an SD card in a USB adapter, with no luck. Anybody out there with this board have the same problem? Any ideas, suggestions?
