Sorry about that Jester2K II , If none of the keys everyone has suggested work , it might be an idea to try another keyboard .
As i said above a swapped keyboard sorted out bios entry on one machine , it also sorted one of my machines out when installing XP , using a USB to PS2 keyboard i could not accept the Licence (F8) , a change to a normal PS2 and it worked.
I can't try again until tomorrow but thats a great idea!!! I didn't think of swapping for a PS2 keybaord.... Although i did manage to accidentally get into the BIOS using the USB Keyboard - but still its an idea!!!!
Sorry for my tardiness, Jester, my mate got back to me but he can't remember for sure (he doesn't have the PB anymore) which key it was, but he thinks it was F2 or F10 that he had to keep tapping on bootup.
