Sklod,
Why don't you try what worked for Alexey in the sister thread (described in his post here)?
I.e. (expanded and with minor variations):
- Remember your current BIOS settings (including boot options)
- Copy BIOS version 0110 (the *.bio version) onto a USB stick (FAT or FAT32)
- Boot to BIOS (F2)
- Restore default settings (F9) and reboot (F10)
- Boot to BIOS (F2 again)
- Shut down, remove power and wait for the board power LED to go out
- Remove the BIOS configuration jumper
- Insert the USB stick containing BIOS 0110
- Power on and wait while BIOS recovery mode completes
- Shut down (if necessary) and remove power
- Replace the BIOS configuration jumper
- Reboot to BIOS (F2 again)
- Restore BIOS defaults (for the new BIOS) and reboot
- Boot to BIOS
- Adjust BIOS settings to your required configuration
- Reboot to OS
I sense that you don't have much time (to waste), and I think this procedure probably has the greatest chance of bringing success.
