Thalaxis, Thanks for your response, but I think you may have missed the point of my message. The VAIO IS a desktop and it runs the 2.59GHZ p4 and is labeled as using hyperthreading, which, although in a non-technical forum I used a euphamism, I understand reserves system resources by allowing programs which are DESIGNED to take advantage of hyperthreading to run more efficiently by "threading" the instructions through the processor. The euphamism was used since at full burn the system shows only 50 percent processor usage. It also doesn't FEEL 2 and a half times faster than my old Athlon 900Mhz. I am, of course, using the memory which came suplied (512 meg) and the supplied video accelerator. The jist of my message is that Vue, according to Steve Bell of E-ON, is NOT designed to use hyperthreading and therefore I am not getting the full advantage of the processor. Some of the forums on Hyperthreading support this statement if the application was not designed to take advantage of it. (Photoshop is. Vue is not.) I suppose what I was really asking in the last sentence was how to access the BIOS on this computer? On splash/startup I see no "hit F4 for setup" or anything like that. It seems that no matter what keys I touch it still just boots up to XP. Sony, of course, merely says "Not allowing windows access to it's resources can damage the system. We recommend not tampering with the BIOS settings which are designed for maximum performance of your new SONY VAIO system" Sorry for any mixup there. The question remains, how do you access the BIOS on this machine since Sony is not going to be forthcoming on this subject? Dr. Michael R. Nash
