2. PCI 1/2 Post Write
Enabling this function will enhance the system efficiency.
3. Vlink 8x support (7VIF 4 only)
Enable this setting to utilize the 8X mode (twice as fast as 4X) offered by advanced AGP
cards. Your VGA card must support 8X mode in order to take advantage of the faster
speed.
4. PCI Delay Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions
cycles. To be in compliance with PCI specification version 2.1 please select Enabled.
Memory Hole
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. If Auto Configuration is
enabled, you must set the DRAM timing function to 60ns or 70ns, depending on the type
of DRAM you install.
System BIOS Cacheable
Enabling this function allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this memory
area, a system error may result. It is advised to leave this setting. Caching the system
BIOS results in better performance than shadowing the system BIOS.
Video RAM Cacheable
Enabling this function will allows caching of the video RAM, resulting in better system
performance. However, if any programs write to this memory area, a system error may
occur.
VGA share memory size (7VIF3 only)
Please leave the default value at [16M] for a stable system operation.
Flash BIOS Protection
The motherboard 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 FLASH utility. When disabled, the BIOS data can be updated by using the FLASH
utility.
