Installation
CMOS Clear
Refer to Table 2-23 for the jumper
settings to clear CMOS. Always
remove the AC power cord from
the system before clearing CMOS.
NOTE: For an ATX power supply, you must
completely shut down the system, remove the
AC power cord and then use JBT1 to clear
CMOS. Replace JBT1 back to the pin 1-2 posi-
tion before powering up the system again. Do
not use the PW_ON connector to clear CMOS.

Core/Bus Ratio settings are de-
scribed in Section 2-7.
The jumper settings for FSB Speed
are JP1 for the370DE6 (Rev. 1.00 &
1.1--Table 2-24a), and JP1&JP63 for
the 370DER//370DEI (Rev.
1.00 & 1.1--Table 2-24b).

1. The auto setting allows the CPU to
set the speed.
2. If the FSB speed is 100MHz, JP63
should be set to "On".
