Note: 1. PC100 Compliant DIMM module is required regardless of 66 or 100
MHz FSB speed.
2. If you want to use DIMM3, DIMM2 must be used as well to let the
system work properly. Just plugging a memory module into DIMM3
with DIMM2 left empty, will make the system unstable.
Step 4. FSB For 66MHz Jumper Setting (JP2,JP3)
If the Motherboard fails to detect 66MHz FSB when using Celeron FCPGA & Celeron PPGA
CPU., Please check the CPU FSB jumper settings on the Motherboard.
