Hi Mr Giga Rep man.
Yes if you have a usb keyboard attached only no problem.
If you have a ps2 mouse attached you have no hope in hell, it locks up and sometime you get a blank bios screen with the mouse arrow clearly visible (that was my clue )
Remove said mouse and the bios works ok.
Took me ages to find the problem not too pleased as I nearly sent the thing back.
Latest bios version, and I even re flashed in vain hope.
