This chapter is designed for explaining how to configure the HOT-591P's hardware. After you install the
main board, you can set jumpers, install memory on the main board, and make case connectors. Refer to
this chapter whenever you upgrades or reconfigure your system.
Jumper Setting
This section describe the necessary proce-
dures and proper jumper settings to
configure the HOT-591P main board.
Jumper pin headers show on right side are
used to configure system clock, CPU
multiplier voltages and SDRAM clock
speed.
System Clock -
Pin Header 1~6 of Jumper JP1,
and JA26, JA27
Pin header 1~6 of JP1, JA26 and JA27 are
used to adjust System Clock from 60MHz
to 100 MHz.
CPU Multiplier -
Pin Header 7~12 of Jumper JP1
Pin header 7~12 of JP1 are used to adjust
CPU core multiplier from 1.5X to 5.5X.
Figure 2-1 : J19, JP1, JA25~JA27 & JP9 location
SDRAM Clock Speed -
Jumper JA25 and JP9
HOT-591P support 100MHz external clock speed AMD 266MHz and 300MHz K6-3D, and
which allows the user to use 66MHz normal SDRAM DIMM or 100MHz PC/100 SDRAM
DIMM. Jumpers JA25 and JP9 are used to set SDRAM DIMM clock speed synchronous with
System Clock (CPU External Clock) or synchronous with AGP Clock.
CPU Voltages Auto/Manual
Jumper- J19
HOT-591P automatically detects and adjusts the voltage to the processor.
Jumper block J19 is used to set Automatically or Manually adjust onboard voltages output
from switching type regulators to CPU by inserting or removing mini jumper from pin
headers. (please refer to page 16)
