System BIOS Cacheable:
When set to “Enabled”, the System BIOS
will be cached for faster execution. The default setting is “Enabled”.
Video BIOS Cacheable:
When set to “Enabled”, the Video BIOS will
be cached for faster execution. The default setting is “Enabled”.
Memory Hole At 15M-16M:
The default setting is “Disabled”. Set to
“Enabled” means that when the system memory size is equal to or greater
than 16M bytes, the physical memory address from 15M to 16M will be
passed to PCI or ISA and there will be 1MBytes hole in your system
memory. This option is designed for some OS with special add-in cards
which need 15M-16M memory space.
Delayed Transaction:
This termination is used by targets that can’t
complete the initial data phase within the requirement of this
specification. One advantage of a Delay Transaction is that the bus is not
held in wait states while completing an access to a slow device. While
the originating master rearbitrates for the bus, other bus masters are
allowed to use the bus bandwidth that would normally be wasted
holding the master in wait states. Another advantage is that all posted
memory write data is not required to be flushed before the request is
accepted. Chipset has an embedded 32-bit post write buffer to support
delay transactions cycles. Select “Enabled” to support compliance with
PCI specification version 2.2.
OnChip Video Windows Size (MB):
This option determines the
effective size of the AGP Graphic Aperture which memory-mapped,
graphics data structures can reside in. When use PCI VGA Card, it must
set as “Disabled”.
*Onboard Display Cache Setting/CAS Latency:
The options are “2”
and “3”. Slower rate “3” may be required for slower onboard Display
Cache. The default setting is “3”. Please do not change this timing
because it is being verified by manufacture.
*Onboard Display Cache Setting/Paging Mode Control:
The default
setting is “Close”. The options are “Open” and “Close”.
*Onboard Display Cache Setting/RAS-to-CAS Override:
The
options are “by CAS# LT” and “Override”.
