Award BIOS Setup Program

B. DRAM Data Integrity Mode
BIOS automatically detects the presence of ECC DIMMs (72-bit modules). However,
to take advantage of ECC you must set this function at "ECC." If any non-parity
DIMMs are installed, the memory operates in non-parity mode only and this
function must be set at "Non-ECC."
C. 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.
D. 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.
E. Spectrum Spread
When Enabled this function will cause lower EMI by spreading the system
frequency spectrum. For normal operation, Disable this function.
F. Power Failure Recovery
Computers using an ATX power supply do not turn back on after the power source
to the computer unexpectedly fails (i.e. electricity outage). Enabling this setting
will allow the system to always turn back on after a power failure. This is especially
important for computers that must be on 24 hours per day.
G. 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.
To Pass the Windows 95 SCT testing, this item should be disabled.
