  How to fix the "BIOS Checksum Failure" problemIf you have in-advertantly enabled CAS2 while in "100MHz FSB" mode and your BIOS reports a "Checksum Failure" upon bootup here is the fix. See picture below for component locations. 
 #1.) Unplug the powercord from the powersupply.
 
 #2.) Unplug the ATX powercord from the motherboard
 
 #3.) Locate jumper JP5 just above the southbridge and next to the motherboard battery. Short pins 2 and 3 for at least 10 seconds.
 
 #4.) Replace the JP5 jumper to the 1-2 position.
 
 #5.) Replace the motherboard ATX powercord and system power cord.
After this you will need to re-boot the machine, enter the BIOS and re-set your perfrences while remembering not to set the RAM CAS timing to 2 while using the 100MHz FSB option.  This problem does not occur if you are in 66MHz FSB mode, and the option is not available while in the 133MHz FSB mode.
