BIOS Configuration
You can change the VXIpc 770/870B Series configuration settings in the
BIOS setup. The BIOS is the low-level interface between the hardware and
PC software that configures and tests your hardware when you boot the
system. The BIOS setup program includes menus for configuring settings
and enabling controller features.
Most users do not need to use the BIOS setup program, as the
VXIpc 770/870B Series controller ships with default settings that
work well for most configurations.
Caution
Changing BIOS settings may lead to incorrect controller behavior and possibly
an unbootable controller. If this happens, follow the instructions for restoring default
settings in the
section. In general, do
not
change a setting unless you are
absolutely certain what it does.
