Configuring Your System 19
Configuring the System Board The system board contains a CMOS Clear configuration jumper, and two
sets of reserved jumper blocks (do not change).
The CMOS and Non-Volatile RAM (NVRAM) settings are only cleared if
the checksum test returns false. Access to specific setup fields is
controlled by a supervisor password or user password.
The Clear CMOS mode removes the password that is stored in CMOS. No
other parameters are cleared.
