PA-2000



Item: 

Pentium 133 jumper setting

Pentium 120 jumper setting

CPU voltage jumper setting

Write-back/write thru cache

Generic 100MHz CPU multiplier settings

Memory configurations



The fastest PA-2000 can go is Pentium 133 

JK1	2-3

JK2	2-3

JK3	1-2 (these three are for 66MHz bus)

JC2	1-2 (x2)



Voltage:

3.3V

J15	3.3V Short and J16 Open

3.5V

J16	3.5V Short and J15 Open



Write-back/Write Trough Cache

JC1 	1-2	WB (default)

	2-3	WT



JP2	Enabled (for hardware reset)

	Disabled (default)





For P120 the settings are as follows (for voltage see above):



JK1	1-2

JK2	1-2

JK3	1-2

JC2	1-2



For 100MHz CPU you need to use the multiplier 1.5 

JC2	2-3

and external clock 66MHz (see above)





Memory is upgradable to 192MB of DRAM. You can use up to 32MB modules.

Therefore all combinations of modules are possible.
