Hello Kit,

Many PCI motherboards have at least one ISA slot on them, in which case you
can. There may be other considerations, especially if the ISA slot shares
an IRQ with one of the PCI slots -- on some motherboards such an
arrangement disallows usage of the PCI slot that is shared when a card is
in the shared ISA slot.

If your motherboard does not have an ISA slot, then no, unfortunately, you
can't use any ISA cards.

Here is some information on VGA Palette Snoop from

}}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
}}This option is only very rarely needed. It should be left at "Disabled"
unless a video device specifically requires the setting enabled upon

I hope that helps.
