4-32 AcerAltos 21000 System Guide
The VGA palette snoop function allows the control palette register
(CPR) to manage and update the VGA RAM DAC (Digital Analog
Converter, a color data storage) of each VGA card installed in the
system. The snooping process lets the CPR send a signal to all the
VGA cards so that they can update their individual RAM DACs. The
signal goes through the cards continuously until all RAM DAC data
has been updated. This allows display of multiple images on the
screen.
Some VGA cards have required settings for this
feature. Check your VGA card manual before
setting this parameter.
Reset Resource Assignments
Set this parameter to
Yes
to avoid IRQ conflict when installing
non-PnP or PnP ISA cards. This clears all resource assignments and
allows BIOS to reassign resources to all installed PnP devices the
next time the system boots. After clearing the resource data, the
parameter resets to
No
.
