PCI/VGA Palette Snoop: If there are two VGA cards in your system
(one PCI and one ISA) and this option is set to “Disable”, data read
and written by CPU is only directed to the PCI VGA card's palette
registers. If set to “Enabled”, data read and written by CPU will be
directed to both the palette registers of the PCI VGA and ISA VGA
cards. This option must be set to “Enabled” if any ISA VGA card
installed in your system requires VGA palette snooping to fix
improper color problem.
Video BIOS Shadow: The default setting is “Enabled” which will
copy the VGA BIOS into system DRAM.
C8000-CBFFF Shadow to DC000-DFFFF Shadow: The default
setting for the shadow feature is “Disable”. When set to enable, the
ROM with the specific address is copied into system DRAM. It will
also reduce the size of memory available to the system.
OS Select For DRAM > 64MB:The default setting is “Non-OS2”.
Set to “OS2” if the system memory size is greater than 64MB and the
operating system is OS/2.
CPU L2 Cache ECC Checking: The default setting is “Disable”. Set
to “Enabled” only if CPU L2 cache has ECC (Error Checking and
Correction).
Assign IRQ For VGA: The default setting is “Enabled”. When set to
“Disable” BIOS will not assign any IRQ (Interrupt request line) for
PCI VGA card. If your VGA card requires IRQ then set this option to
“Enabled”.
After you have made your selection(s) in the BIOS FEATURES
SETUP, press the <ESC> key to go back to the main program screen.
