have you tried another keyboard?
I have tried three different keyboards but still they are not accessible. Mouse is working properly
Does the led on the keyboard light up or not?
Is it detected during POST?
Try these steps:
Try to do a CMOS clear of the board.
Put the bios jumper to the maintenance mode.
Without pressing F2, it should go into the Bios Maintenance Mode, then try to use the keyboard.
Let us know how it goes.
Still Keyboard is not accessible
Thanks for reply
is it PS/2 keyboard? try usb keybord and wireless keyboard?
