PCI/VGA Palette Snoop
The VGA "palette" is the set of colors that are in use by the video card when it is in
256-color mode. Since there are thousands of colors and only 256 can be used in that
mode, a palette containing the current colors is used. Some special VGA cards,
high-end hardware MPEG decoders etc. need to be able to look at the video card's
VGA palette to determine what colors are currently in use. Enabling this feature turns
on this palette "snoop".
This option is only
very
rarely needed. It should be left at "Disabled" unless a video
device specifically requires the setting enabled upon installation.

Auto Detect PCI Clk
This feature allows users to determine whether the BIOS will automatically reduce the
EMI (Electromagnetic Interface) and the power consumption by shutting down the
unoccupied or inactive expansion slots. If
enabled
, the BIOS will monitor the PCI
slots and will turn off the clock signal to all the unoccupied or inactive PCI slots. If
disabled
, the BIOS will not do the thing mentioned above. It is recommended that
users enable this feature to save power and reduce EMI.
Spread Spectrum
This BIOS feature allows you to reduce the EMI of your motherboard by modulating
the signals it generates so that the spikes are reduced to flatter curves. It achieves this
by varying the frequency
slightly
so that the signal does not use any particular
