Usually on Compaq's to access BIOS you hit the F10 key. I have some Deskpro 2000's. When hitting F10, nothing happens. Usually on the Red and white screen where is says Compaq, on the lower right side, you will see (F10 for setup), but on these models there is nothing there. I need to get into the BIOS to set the date and time but do not know how to access it. I would appreciate some help. Thanks.
