B. 8-bit I/O Recovery Time & 16-bit I/O Recovery Time
Back-to-back CPU or PCI master originated 8-bit and 16-bit cycles have an
arbitrary delay of at least 3.5 system clock cycles. This category is used to add
additional recovery delay between 8-bit and between 16-bit cycles. This delay
takes place because the PCI bus is much faster than the ISA bus. The options
are 1 to 8 and N/A.
C. Memory Hole at 15M-16M
Enabling this function will reserve the memory address space between 15MB
and 16MB for ISA expansion cards. However, enabling this function will result
in not allowing the system to have access to memory above 16MB. Please note
that some expansion cards require this setting to be enabled. The default setting
is Disabled.
D. Flash BIOS Protection
The mainboard manufacturer developed BIOS protection technology that protects
the System BIOS from accidental corruption by unauthorized users or computer
viruses. When enabled, the BIOS data cannot be changed when attempting to
update BIOS with the the FLASH utility. When disabled, the BIOS data can
be updated by using the FLASH utility.
E. Hardware Reset Protect
When this function is enabled, your PC's hardware reset button will not function.
This function is especially useful to prevent accidental resets for file servers and
routers, etc., which should be available 24 hrs/day. When disabled, your PC's
hardware reset button will function normally.
F. Spectrum Spread
When Enabled this function will cause lower EMI by spreading the system
frequency spectrum. For normal operation, Disable this function.
