Bios Post Bug K8s 755a Main Board

In order to locate a schematic for a specific motherboard, you need to know the motherboard's manufacturer name, mode number and revision number which is stamped on the board. You cannot ask for a computer's motherboard diagram based on the computer brand name and model number.
How to Check Your Motherboard Model Number on Your Windows PC
You can use the the aforementioned link to also get the same info specs of the motherboard without opening the case by using the Command line (CMD.exe) or by downloading a GUI based software app.
However, I prefer looking at the main board for the stamped info.
How did you determine that the CMOS chip is re-configuring itself?
Are you confusing the BIOS with CMOS, which are two separate and distinct components.
If the CMOS battery on the motherboard grows weak, or becomes dead, your BIOS settings will reset each time you power off the computer.
Most CMOS batteries are replaceable; some manufacturers solder them in place.
One of the first tell tale signs of a weakening or dead CMOS battery, is having to reset the system clock.
Try changing the CMOS battery; make sure your computer is unplugged from the wall outlet (or Back-UPS); then replace the CMOS battery; plug the computer into the wall outlet (or Back-UPS); power up your computer, enter the system BIOS and configure it to your specs; remember to save the changes; warm reboot; after POST and O.S. start-up; turn off the computer normally- wait 10-20 seconds, do a cold boot to verify that the system BIOS configuration did not change.
Unless you had an electrical surge or spike that would damage the CMOS chip, in which case you might get a checksum error or.... someone is playing tricks on you by resetting the CMOS chip via its jumper; the only other culprit I can think of off hand is virus code infection to the CMOS chip.

Restart your computer
during the boot process you will see on the screen to press a certain key usually Delete or F2 to enter setup
this will differ depending on which bios you have
Press and hold that key during the boot up process to enter BIOS
if you have changed any of the BIOS settings by mistake
you can load failsafe or optimised defaultsusing the arrow keys you can after you make any changes in BIOS press Esc then press the F10 button save to cmos to restart
CMOS is an on-board semiconductor chip powered by a CMOS battery inside computers that stores information such as the system time and date and the system hardware settings for your computer..
this will reset your cmos

Hi,

I have no personal interest or association with any product that I may suggest.

Unfortunately, you did not provide the model so my suggestions are generic

There are some default passwords that you should try first:

1. AMI
2. Award
3. bios
4. setup
5. cmos
6. concat
7. AMI_SW (case sensitive)
8. AMI!SW/
9. AMI?SW/
10. j262

If these passwords didn't do the job, please try the following options:

Option #1:

You can physically remove the Bios/CMOS PROM chip from the motherboard and send it either to the motherboard manufacturer or a Bios developer for replacement of flashing. You can also send the entire motherboard to a facility experienced in these operations.

Option #2:

If the motherboard has a flash updateable Bios/CMOS PROM chip, then you can download a fresh Bios update and re-flash the PROM to eliminate the password.

Option #3:

Tthere are programs (utilities) and (cracks) that can be used to try and either identify the password or remove it forcibly from the PROM chip. Utilities to recover passwords are extremely expensive and are usually only sold to manufacturers and others involved in hardware and software development.

try to clear the cmos.Take the battery out for a minut.Than restart....hope this helps

Sounds like your BIOS update did not complete successfully. Head to the board manufacturers website and check if there is some way you can reload the BIOS and recover from this. Most boards now have dual bios which means that if one bios chip fails or an update fails, you can reload the stored BIOS through the other chip. If you are unable to recover from a failed BIOS update, you may need to purchase a replacement BIOS chip from the board manufacturer. You may even be able to reload the original BIOS onto the chip through your local PC repair store so give them a call and enquire..

You have a corrupted bios file or files. This is what the checksum means. You need to download the correct bios onto a floppy disk. That floppy disk needs to formatted as a system / startup disk BEFORE you copy the bios files to it. Then put the floppy into your floppy drive, turn the pc on and try to get into the bios screens. If the keyboard error is preventing this, go to the mainboard manufacturers website and check the correct manual for the board looking for the procedure to recover from a bios failure. If this board if no older then 5 yrs, it should have this feature. Follow the recovery procedure to rewrite your bios. When that is fixed, undertake the bios update procedure. ONLY do this if you fully understand and accept the risks otherwise, take it to your local professional. If your board does not have the recovery feature, replace it !!unless you are able to replace the CMOS chip with one which has the correct bios burnt onto it. As most modern boards have CMOS chips glued and soldered to the board, this may not be an option..If the bios chip is socketed, contact your local computer shop, or the boards manufacturer to request a replacement. Your issues all arise from your bios issues so fix that and all should be well..

1st remove ur mother board battery and clear cmos and press reset when machine start then shut down and change a new battery and fixd cmos. i hope ur problem will solv

Have you tried clearing the CMOS by removing the battery with PSU off and then shorting the 'reset cmos" (or similar) pins on mobo?

Also found this on the ASUS web site under the specs for the P5NT WS board...

ASUS CrashFree BIOS 2
The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support DVD. Users can reboot their system through the support DVD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

Have you tried this?

1801 microcode patch erro download free plz

For the M925G I can find a V8.0 and v9.1b motherboard on the PC Chips web site but not a v7.3. At any rate this manual clearly shows there should be an option to enable or disable the Ethernet port on the BIOS Features Setup Page near the bottom. If the option is not there and I would be more inclined to think that the wrong firmware may have been flashed to your board. You might try downloading and flashing the BIOS update again, making sure the checksums match when the procedure is complete. By the way the link to the manual I?m referring to is here: http://www.pcchips.com.tw/PCCWeb/Products/ProductsDetail.aspx?MenuID=0&LanID=2&DetailID=255&DetailName=Manual.
