Configuring the System Board
There are two configuration switches on the system board:
❑
CMOS Clear switch
❑
Onboard VGA Interrupt (AGP_INT) switch
When the CMOS Clear switch is in the Normal position, it provides
normal access to the BIOS Setup Utility.
The Central Processing Unit (CPU) input clock is forced to remain at 100
MHz (fast mode), and the Basic Input/Output System (BIOS) uses the
User CMOS settings (as opposed to the System CMOS settings).
The CMOS and 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.
When the CMOS Clear switch is in the Clear position, the password that
is stored in CMOS is cleared. No other parameters are cleared.
If you install a VGA PCI add-in card, you can use the AGP_INT switch to
enable or disable the onboard VGA controller.
✍
The configuration should never need changing unless otherwise directed by a technical
support or service technician.
