DH61CR PS2 port not working after upgrading 48 to 120

Hello

Having a problem with DH61CR motherboard after BIOS update to 120. (PS2 keyboard not working)

I've noticed that keyboard works in freedos, but in bios and windows enviroment dosent work.

Previously i've had this problem aswell with other computers with this motherboard and replaced PS2 keyboard to USB one.

The reason of upgrading bios is cause im upgrading to ivy bridge cpu (and before upgrade it warns that its recommended to upgrade bios)

But this time I have 5machines with this motherboard and i bet i'l have same problem with every computer.

Any suggestions?solutions?

I've tryed force flashing bios (with jumper off and bios file on usb drive) and tryed turning off computer + taking out cmos battery for 30min.

Thanks for joining the Desktop Board community.

If the computer current BIOS version was 0048, you had to go to version 0099 before updating to any later BIOS version; otherwise, you will encounter issues afterwards.

See BIOS release notes for more information: http://downloadmirror.intel.com/23393/eng/BE_0120_ReleaseNotes.pdf http://downloadmirror.intel.com/23393/eng/BE_0120_ReleaseNotes.pdf

Yes, i am aware of this. Thats what i did, updated to version 48, then 99 and then up to 120.

Bios update utility wont let update to 120 anyways if i havent updated to 99.

The board BIOS cannot be reverted to 0048 once you updated to a later version. You would need to use USB port or USB hub to have more ports available for your computer.
