I dont have a bios sys. on my hp pavilion xt856, I had to crash the sys due to an unknown virus. I loaded xp on the disk and compleatly re-formatted the disk. it loaded successfuly, then it rebooted its self to start. it only got to a blinking light. the hard drive is fine. I plugged in an old hard drive that had 95 on it. it loaded up fine, then the plug and play feature kicked in. when it was finished it had said some things about a mother board bridge and things of that nature had been found as plug and play and asked me to re-boot. when I rebooted, the same thing happend to the disk with 95 on it. I didnt install anything on that disk. I tried to get to bios with all the short cuts. it apears that I dont have one. the big blue hp sign shows up on boot, but then nothing else. no matter which button I push. Its got me stumped, please tell me where to go from here.
