If you have been locked out of your system because you forgot your pass-
word or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JP2 to pins 2 and 3
3. Wait for 2 seconds, then return jumper JP2 to pins 1 and 2.
4. Power on the system again.
By following this procedure, you will erase your password and reset the
CMOS to the BIOS defaults.
Fan Speed Detect
When using Intel’s LANDesk
system management software,
you may monitor the status of
the CPU Fans by connecting
them to the Fan1 and/or Fan2
connectors. You will NOT be
able to monitor your CPU fan
with the other Fan connectors.
Soft Power Connector
The Soft Power Connector is
part of jumper block J47. The
Tomahawk BX/A+ uses the chipset for power management, including turning
on and off the system. If the Power Button Function option in the BIOS Power
Management Menu is set to On/Off (which is the default), pressing the power
button once after the BIOS has booted up will turn the system on and off. If
the Power Button Function option is set to Suspend, pressing the power
button once will wake the system or send it to Suspend mode. In this case,
you cannot turn the system off unless you shut down through the Windows
operating system or you hold the power button down for four seconds.
