Treat me nice here. I just know enough to get into trouble. I have a MSI Ultra2/ARU Main Board with a AMD Athlon XP2100 CPU at 1.7 GHz. I recently flashed the BIOS, and in spite of my ignorance, I think I got away with it. One problem that I think is connected, however. Sisoft Sandra and Belarc both say that I now have an XP1500 running at 1.3Ghz. I think that my FSB was defaulted back to 100MHz. That or probably something along that line has changed that is causing the BIOS to think that it is an XP1500. The chipset FSB is @200/266 MHz. The CPU FSB clock is set @ 100. Can anyone gently shove me in the right direction here as to what corrections I can make? I will grin and accept all admonishments.
