Warning!!!
ATX motherboards are always live!!!
pull power plug when removing cards, memory or jumpers otherwise you run the risk of frying your motherboard. I know many a PC user who has made this mistake and let the blue smoke out of his /her motherboard.
okay that said
JP1: on/off power switch
JP3:IDE Hard Disk LED
J9A1: header for USB 2&3
JP14,JP15 cooling fan connectors
JP18: reset switch
JP13 changes between FSB 100 or 133 (2-1 133FSB) (2-3 100FSB)
thats all you need to know
if you get a black screen after turning the unit on try setting the FSB to 100
(if your computer only works in 100FSB you need different ramalso try running with only one stickof ram first )
be carful the some of the jumpers on the motherboard control voltages to the chips don't mess with them
ohh the clock multiplier for the PPC chip is j1:
1100 =1.0
1011 =2.0
1111 =2.5
0111 =3.0
0001 =3.5
0101 =4.0
1000 =4.5
0100 =5.0
0110 =5.5
0010 =6.0
1010 =6.5
1101 =7.0
1110 =7.5
0011 =8.0
so if you change the FSB to 100
set the clock mutltiplier to 6.0
6 x 100 = 600mhz
4.5 x 133 = 600mhz (yes i know the math comes to 598)
