I have a CB649M-SI motherboard (made in 1999) from Future Power. The BIOS version is 649.06 (this is the latest I could find), and the BIOS date is in July of 1999. When I start up the computer, it says AWARD BIOS 4.51PG at the top of the screen. This is a Socket 370 motherboard. I have a 366-MHz Celeron in it now. The manual says that this board supports a 100-MHz FSB. At motherboards.com, I saw FCPGA and FCPGA2 versions of the Celeron processor. What is this difference, and could it have any effect on whether or not the processor could work in my system? Is there any possibility that the 1-GHz or up models could work in such an old motherboard? Thanks in advance for your help!
