Set this parameter to Enabled if you want the system BIOS to run directly from
the cache memory, thus allowing your system to function faster. Set this to
Disabled to run the system BIOS from RAM. The default setting is Enabled.
Set this parameter to Enabled if you want the video BIOS to run directly from the
cache memory, thus allowing your system to function faster. Set this to Disabled
to run the video BIOS from RAM. The default setting is Enabled.
To prevent memory address conflicts between the system and expansion boards,
reserve this memory range for the use of either the system or an expansion board.
This parameter allows you to select the DRAM operating mode. Setting to ECC
turns on the error check and correct (ECC) function. ECC automatically corrects
any single-bit errors detected. For multiple-bit errors detected, ECC only issues
an NMI to signal the operating system of the multiple-bit error detection. Setting
to Disabled deactivates the function. The default setting is ECC.
Enabling this parameter allows BIOS to create a multiprocessor (MP) table for
Windows NT use. In a single-processor system running Windows NT, you may
disable this parameter to enhance system performance.
In cases when this parameter is enabled before installing Windows NT in a single-
processor system, you may upgrade to a multiprocessor system without
reinstalling Windows NT. The default setting is Enabled.
