F. PCI/VGA Palette Snoop
A system may have two display devices present: a VGA-compatible interface
and another graphics controller. In this case, both devices implement the color
palette registers at the same I/O addresses. The configuration software must
program one of the devices to actively act as the target, while the other device
is programmed to quietly "snarf" the write data from the bus as the data flies by
on it's way to the target.
＊
Some non-standard VGA cards or MPEG video cards may not show
colors properly. Setting this function at
Enabled
can correct this problem.
G. OS Select (For DRAM > 64MB)
If your system DRAM is larger than 64MB and you are running OS/2, please
select
"OS/2" as the item value. Otherwise, set the item value to "Non-OS/2."
H. Shadow Memory
BIOS can copy adapter ROM from address C0000h through DFFFFh to RAM
for faster execution. Shadow setting is chipset specific and dependent on
system hardware.
