BIOS Setup
3.1.3.8 Video BIOS Cacheable
As with caching the system BIOS, enabling the Video BIOS cache will
allow access to video BIOS addresssed at C0000H to C7FFFH to
be cached, if the cache controller is also enabled. The larger the range
of the Cache RAM, the faster the video performance.
3.1.3.9 Memory Hole At 15M-16M
In order to improve system performance, certain space in memory can
be reserved for ISA cards. This memory must be mapped into the
memory space below 16MB. When enabled, the CPU assumes the 15-
16MB memory range is allocated to the hidden ISA address range
instead of the actual system DRAM. When disabled, the CPU assumes
the 15-16MB address range actually contains DRAM memory. If more
than 16MB of system memory is installed, this field must be disabled
to provide contiguous system memory.
3.1.3.10 AGP Aperture Size (MB)
This field is used to select the size of the system RAM that can be
allocated to the AGP for graphics purposes. Aperture refers to a
portion of the PCI memory address range that is dedicated for the
graphics memory address space. Host cycles that hit the aperture
range are forwarded to the AGP without any translation.
3.1.3.11 Init Display First
This field is used to select whether to initialize the AGP or PCI first
when the system boots.
AGP
When the system boots, it will first initialize the AGP.
PCI Slot
When the system boots, it will first initialize PCI.
