Question: AMD Sempron 2800 & bootable restore cddvd

I am building a computer for my friend. I went to Fry's and got that deal on AMD Sempron 2800 with PcChip motherboard. Installed windows XP SP2, every thing is fine. However when I go to device manger, windows is reading processor speed at 1.2GHZ. I went to AMD site and found few article online about the conversion of AMD sempron to Intel speed. To my understanding Sempron 2800 should be close to 2.2GH. I check the jumper setting on the motherboard seems correct. In BIOS under CPU PnP setup, I left it disabled as per Motherboard manual for detecting the processor speed automatically. My question is that is Sempron 2800 should be showing as 1.2 GHZ? or I need to change BIOS setting. Another question is that I want to make a system restore cd, so if the system crashed they can reboot the computer and restore it. I have Norton ghost 3.0 and made backup and able to restore the system from the backup cd-dvd, the only problem is that recovery wizard is not very user friendly(for e.g., no mouse support). Anyone has similar motherboard and processor or have any knowledge please help. Thanks, Muhammad
