Shadowing improves the firmware's performance because the firmware can be read
by the CPU through the 16- or 32-bit DRAM bus as opposed to the 8-bit XT bus.
However, shadowing also results in reducing the amount of high memory (640
KB to 1 MB) for loading device drivers. Shadowing is used mostly for ROM chips
on ISA cards and not for PCI cards. Shadowing and playing games at the same
time may result in system instability as some games access the RAM memory area
being shadowed.
K. Onboard NCR BIOS
Some NCR cards don't have BIOS onboard. Set this function to Enabled if the
card don't have BIOS onboard. Disabled this function if the NCR card is with
a BIOS onboard.
