I have three system boards, i-Will, MSI, and ECS with AMD CPU’s of 2.2, 2.0 and 1.6 GB. After insuring PC2100 DDR memory is installed, I still cannot increase size of FSB above 100 mhz and still boot up next start-up! Bios reports bus speed is 266 MHz, but speed still reported at 1.2 GHz. What else to be done?
