Allows the video BIOS to be cached to allow faster
video performance.
For some old I/O chips, after the execution of an I/O
command, the device requires a certain amount of
time (recovery time) before the execution of the next
I/O command. Because of new generation CPU and
mainboard chipset, the assertion of I/O command is
faster, and sometimes shorter than specified I/O
recovery time of old I/O devices. This item lets you
specify the delay of 8-bit I/O command by count of
ISA bus clock. If you find any unstable 8-bit I/O card,
you may try to extend the I/O recovery time via this
item. The BIOS default value is 4 ISA clock. If set to
NA, the chipset will insert 3.5 system clocks.
The same as 16-bit I/O recovery time. This item lets
you specify the recovery time for the execution of 16-
bit I/O commands by count of ISA bus clock. If you
find any of the installed 16-bit I/O cards unstable, try
extending the I/O recovery time via this item. The
BIOS default value is 1 ISA clocks. If set to NA, the
chipset will automatically insert 3.5 system clocks.
This option lets you reserve system memory area for
special ISA cards. The chipset accesses code/data
of these areas from the ISA bus directly. Normally,
these areas are reserved for memory mapped I/O
card.
