ok so. I have decided to make it a kitchen recepie computer, no internet. My questioin is since I bought a practice board off ebay and flashed the bios to 4r4cboxa.86a.0020.p14, I am now able to upgrade to 600mhz. or slower according to the warning message of the system not being able to support the cpu voltage. "your system has been halted. Please install cpu of 600mhz or lower. I have the powerleap adapter and stuck in a 700mhz 256k 1.75 volt cpu. It didnt like it. I was under the impression that the powerleap slot 1 adapter would adjust the voltage. It does have jumpers for 66 100 or 133 front side bus and does have 8 pins to install jumpers on up to 4 jumpers to select proper voltage ranges. (doesnt go up to to2 volts but close (1.8 to 1.825 volts.)
