1.1 One Jumper to Set CPU , Simple Jumper

No more CPU jumper setting when you use Single Processor
Intel 133Mhz,
CYRIX 166+,
AMD K5-133 CPU.
You just install CPU directly and Power On. (At the moment, JP6: 1-
2 and JP7: 2-3 SHORT; JP8/JP9: 1-2 SHORT )
A: Using Intel CPU (Ensuring JP8/JP9: 1-2 SHORT)
CPU Speed JP6 JP7
Intel 100Mhz 1-2 SHORT 1-2 SHORT
Intel 166Mhz 2-3 SHORT 2-3 SHORT
Intel 200Mhz 2-3 SHORT 1-2 SHORT
Intel 233Mhz 1-2 SHORT 1-2 SHORT
B: Using AMD K5/K6 (Ensuring JP8/9: 1-2 SHORT)

AMD K5-100 1-2 SHORT 1-2 SHORT
AMD K5/K6-PR-166 2-3 SHORT 2-3 SHORT
AMD K6-PR200 2-3 SHORT 1-2 SHORT
AMD K6-PR233 1-2 SHORT 1-2 SHORT
C: Using CYRIX 6x86 CPU ( Ensuring JP6: 1-2 and JP7: 2-3 SHORT)
CPU Speed JP8 JP9
CX 133+, 55Mhz 2-3 SHORT 2-3 SHORT
CX 150+, 60Mhz 2-3 SHORT 1-2 SHORT
CX 200+, 75Mhz 1-2 SHORT 2-3 SHORT
When you want to install two CPU, they are perfect are the same
voltage 2.8v (P55C) or 3.3v(P54C). Different voltage can’t be
used together. Installing the 1st CPU at U4 socket!
