Pentium® II (Klamath) - Processor-Card Type A - Jumper Settings

Jumper Description
J20
J38
Clock speed jumper block. The default setting is
66.66Mhz. Use the appropriate microprocessor clock
speed for the microprocessor that you have installed.
J27

installed on J28 or J29.)
For the core/bus fraction 4 (266MHz), the jumpers
are installed on J27, J28, and J29, no jumper is
installed on J30.
J39
J14
J15
J16
J32
J13
Voltage indentification selection jumper block for
primary VRM. The default setting is J14. (A jumper
is installed on J14, no jumper is installed on
J39, J15, J16, J32 or J13.)
J40
J33
J35
J36
J34
J37
Voltage indentification selection jumper block for
secondary VRM. The default setting is J36. (A jumper
is installed on J36, no jumper is installed on
J40, J33, J35, J34 or J37.)
J17
J18
Microprocessor memory controller (PMC) frequency
selection jumper block. The default setting is
66.66MHz.
J9
J10
J12
Reserved.
J8 PCI/ISA bus jumper. To ensure that the server operates
properly, do not move this jumper from its default
position.
