To cut a long and dull story short, I bought the parts for a new PC and have been trying to get it stable for about a month, so far….
Part of this saga was re-flashing the motherboard bios. It has a simple boot loader during POST to do this. The boot-loader called qflash gives a checksum for the binary file it has loaded. I could not find the expected value for this anywhere so filled in a technical support form and braced for the mysery.

Question : When upgrading the bios, I was given a checksum by the qflash utility. I cannot find anywhere what the correct checksum is. Please can you confirm this value for f4 and f5 bios updates.
Answer – 844406
Answer : Hi,
Please ensure you have the correct BIOS update.
Please try to reset the CMOS –
1) Disconnect the power cord from the power supply. Remove the CMOS battery (the flat silver disk) from the motherboard using a srew drive or similar implement. Leave it out for a minute or two, then replace it and power on the system. The BIOS settings should have been reset, allowing the computer to boot.
2) Go into the BIOS – “Load optimized default”
3) Save settings and exit.
4) If this doesn’t work then try “Load Failsafe default”
UUUUGH! Is this automated or are they stupid?

Question : This is not an answer to the question I have asked….
More to the point how am I supposed to know if I have the correct bios update (As you suggest) without the checksum.
So more precisely:
What is the valid checksum in qflash for you bios f4 and f5 on a GA-P55M-UD2(rev. 1.0).
I believe this will be a 4 digit numeric or alphanumeric value…
Answer – 848338
Answer : Hi,
We can provide checksum for you but before the providing, please give us more information.
– What is “I was given a checksum by the Qflash utility”? Is that you pressing F8 in bios, entering Qflash menu and get checksum error message or other condition?
– Please also confirm the bios resource. We want to make sure the bioses for this model.
– Also check the original bios on your P55M-UD2. Did you ever flash bios successfully on this motherboard?
Sounds like stalling to me.

Question : I refer to wanting to flash the bios, to the latest version. After the qflash utility has loaded the binary file, extracted from the exe provided on your website the qflash utility gives a 4 digit checksum and asks for confirmation before writing to EEPROM. To make use of this check, one needs to know the correct value.
This is the checksum for the bios firmware, not the variables held in ram.
I enquire about both the f4 and f5 checksums since I have flashed a system to f4 and wish to verify it was correct. Also to flash a further motherboard to f5.

Answer : Hi,
Here they are:
P55MUD2.F4 – 7400h
P55MUD2.F5 – 2D00h
This took 10 days to get and answer, why cant it just be in the bios download, a text file would do! Also why is the bios in a self extracting .exe file?? Whilst this appears to be a well spec’ed board, I don’t think I will be buying Gigabyte again, I have been generally unimpressed by them in more areas than this.
