    Very Helpful Master d0p3 :)

    I know what beta means and I am fully aware of the risks I take.

    Here the solution that might help somebody else.

    The link on ASUS site to Beta version 1.09 seems to be linked to a wrong file. BIOS version for a different board, so dont try installing it, it will not work. Install Bios version 1.08 it will work.

    Download file to your PC and then extract the file to a floppy, rember the name of the file then restart the PC.

    Bios upgrade is easy with this board, just hit ALT+F2 at start up and it will start the bios update program. Follow the prompts.

    Done :)

Four bios versions which do I flash?

Gigabyte GA-Z77X-UD5H

F15q and F15o are BETA versions.
Meaning in actuality, they use the consumer as a guinea pig, and see what the results are. Then they might 'tweak it', and call it good.
Becomes an Alpha version then.

['Tweak it'.
Work the bugs out that have been found by the consumer]

My bad. Let me use the 'prose' they use,

"What is BETA?
BETA describes a new version that is reliable yet may not include all the features of the final product. During this phase we are previewing new features and gathering customer input to insure our product provides the best experience possible."

Moving on....

Next, the logical thought is; to download the Latest version.
The thinking is that the latest version has all the bugs worked out.

However this may be a fallacy for your particular motherboard.
The latest version may not work.
Makes you feel all warm, and fuzzy inside, huh? (NOT)

The procedure to use when updating BIOS, and using any version; is to make sure you keep a copy of the old one.
When upgrading, you will be asked if you wish to make a copy, of the old BIOS program.

YES, is the answer.

Something happens with the new version, you have the old version to revert back to; and at least be able to use your motherboard.
No BIOS? Might as well use the mobo for a Frisbee.

So,......looking at the different versions that you see, look at each one's date.

F5 is 03/28/2012. March 28, 2012
Indicates Enhanced overclocking capability.

What does F6 do, that came out April 26, 2012?
1) Improved Processor overclocking, using a processor based on the Sandy Bridge Core,

2) Brings support for using an Intel Xeon processor.

Now look at the next version, F7.

All the improvements you see listed for each version, are culminated in the newest version,


That is, the newest version that has proved to be stable.
Supposedly the 'bugs' are worked out.

The other two versions F15o and F15q, again; are BETA versions.
Should ONLY be used by those who have a lot of experience, and know what to do if it fails.

So this leaves us with F14.
HOWEVER again, make SURE you make a copy of the old BIOS version.
When updating you will be asked.


(ALSO, if your power goes out in the middle of a BIOS update, kiss the motherboard goodbye; unless you made a copy of the existing BIOS version.

This is why I, and others state; that unless there is a definite reason to upgrade the BIOS program on your computer -> DON'T)

ASUS K8V-MX Motherboard recognizing 320 GB SATA harddisk. Why?

It could be that your BIOS needs updating for this motherboard. Take note of your BIOS version when your computing is booting. Try hitting the Pause key to freexe the screen, but if no luck go into BIOS and see if the BIOS version is listed. You typically get in BIOS by hitting the "Delete' key on your keyboard when the computer starts up and the first bunch of words appear in white characters (might be a light grey)
Go here:
Latest BIOS (note its a beta version ie not formally released) is
K8V-MX Beta BIOS 0501
Latest beta BIOS.

I was installing software on the computer when it froze so shut it down. When restarted it wouldnnt reboot. Error came up 01888: Invalid RFID Serialization Info Area or Bad CRC2

What software,???

Have you changed the operating system from what the laptop came with.

When it posts see what version bios you have, then go to the website
of your MFG and see if there is a newer version, if you have the newest,
flash the bios to an older one, if you have a older one flash to a newer one.

If you don;t have your manual, get it while you there, are read how to flash your bios very carefully, make sure you know it well before you do this.

You can also try, system restore, or recovery, again, when your laptop
first posts, at the bottom you will see commands, one for enter bios,
boot order, and so on one should be restore or system restore.

The error you posted is a bios error, so it depends if you have changed things or systems.

Try and restore the unit first and see if this works.

Hp Compaq Presario C700 bios update and numlock function is not work

Hi, did you download a beta version of the bios? If so you will have to try and install the last bios.
Which version of bios do you have?
Did you download the correct one for your serial number?
I think the current one is F.34
Did you make a backup of your old bios?
What was the reason for the bios update? I think this only improves bios security when a password is used.
If you haven't backedup your old bios, sometime there is and old bios file on one of the setup discs that came with the laptop.

I will try and help more-

Regards - Anthony

The file you downloaded should have provided instructions for its use wither in a redme file or on the page it was downloaded from. There are several different ways for flashing the BIOS. Many still require booting from a DOS disk and using a DOS-based flash utility to perform the update. Others are Windows executable files that can flash the BIOS directly without having to start a reduced-functionality environment, but they require Administrative access to the computer to perform the update.

If what you downloaded was a Zip file, there should be instructions included with it.

You also want to make sure that it the the correct BIOS you are flashing. If it is not the correct version, you risk permanent damage to your computer.

Update my Intel D845GVSR Bios Version to VA84510A.86A.0056.P20, then my USB driver is not working at all.

There is a simple solution for it..... Just reboot the system and enter to Bios setup by tapping Del key
Press F9 key and set it to default settings... Just save and exit.... USB Ports works fine.....

I have seen this issue before.... When you update the bios you need to reset the BIOS settings otherwise it is using an invalid set of options, you need to enter BIOS and load Defaults, (usually by pressing f9) hopefully after that your system should load properly...

CMOS battery drains after one startup. Gigabyte GA-K8N-SLI

OK lets see here! Make sure your CMOS jumper is set properly on the board(Set to Normal) or Did you configure your bios after flashing the bios(going into bios and Load Optimized Defaults!)? or I don't think it would be another device in the system, but you can try troubleshooting by starting up with only what you need to run the machine (Mobo, memory harddrive, keyboard and mouse) then one by one adding devices back! or Did you have problems like this b4 you flashed the bios! Try flashing the bios back to an older version! post back if anything new or if i'm way off! Good Luck regards, babb
