POST code 5A means "Resetting PATA/SATA bus and all devices", so please disconnect all HDD/ODD and other devices except keyboard & mouse, then try to boot system again
I tried disconnect devices before. But no changes. I too tried disconnect RAM, graphic card, but I mean there is no problem. I mean that 5A BIOS is any kind of BIOS. Sometimes when I replace the jumper to position 1-2 I have there BA BIOS. This code was written on monitor when the PC was good everytime when I switched on PC . I mean it is not any error. But thank you for your replay.
This PC write on strartup now. I do not why I only tried disconnect devices and than i connected them back. But this screen say that the "AHCI BIOS not installed. The problem is, that I can not boot new installation of BIOS from CD or flash disk !
This creen appear only for 2 seconds and then come normal boot screen
When I touch the F2 button nothing will happen.
Suddnely appear this sreen (sometimes there is BABIOS, sometimes 5ABIOS) I discover that the BA and 5A BIOS is still changing when I have still placed jumper to position 2-3. In every PC start its difference.
When I touch the F2 button nothing will happen still. Then I can only restart a PC with button on chassis. Buttons on keyboard are irresponsive.
The best way to upgrade BIOS, especially when you have booting issues will be by BIOS recovery mode.
Download the file named DP0572P.BIO
Stick it on a formatted pen drive.
Remove BIOS jumper.
Turn the system ON with the USB pen drive on the back usb port.
Leave it for 15-20 minutes.

Hi, I tried this metod, but only for max. 10 minutes and on no formatted disk. I will try it for 20 minutes or longer. With pen drive you mean a flash disk ?
Thank you for your advice
use an usb-stick, and unplug everything else.
Do you mean unplug too the keyboard, HDD, DVD mechanic, graphic card ?? Write please complete list of devices which I must unplug, thank you.
I tried instruction from Span1shUk. I switched on the PC, but the flash disk only several times blink and it was all. I leave it for 30 minutes, but nothing happen.
pls try using a USB ODD... or a USB flobby drive...
Intel recommend using USB flobby drive to settle bios issues.. because the board reaction will be more obvious to the user by seeing the flooby reading sound
Any other idea how rescue BIOS. Or can me someone tell that this is hardware problem or inreparable software problem ? Must I change my motherboard or can I repair it. I mean I must buy new moterboard. I tried everything.
I have not USB floppy drive and this motherboard has not port to connect normal floppy drive. I do not know what is USB ODD, but I have only normal flash disks.
According to my guys in Intel, they recommend using USB flobby drive revive the board. however if you are at witts end, you may consider calling intel during working hours or seek your place of purchase for a exchange or warranty..
i know we all had tried our best to resolve the problem. but now the best option is to replace the board.. i dun think you need to change or personally get a brand new mainboard.. call intel support or yourplace of purchase for assistance.
Bios problem sometimes can lead the user to craziness. as long as you have the right tool to solve the problem..
i never tried/heard using flash drives to flash bios. but it has been 100% perfect for me using USB flooby drive to flash the corrupted bios.
ps: if anyone ever tried flashing bios using flash drive, pls teach me too..
Know anyone the phone number to intel support for Czech republic ? And is that call free or must I pay it ? I did not find these informations anywhere. Thank you all for advice.
