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 relevant to the memory-mapped graphics data of the
AGP card installed in your system. Leave this in its default setting.
3.1.3.11 Init Display First
This field is used to select whether to initialize the onboard VGA/
AGP or PCI first when the system boots.
PCI Slot
When the system boots, it will first initialize PCI.
Onboard/AGP
When the system boots, it will first initialize the
onboard VGA and/or AGP.
3.1.3.12 On-Chip VGA
This field is used to enable or disable the onboard VGA.
3.1.3.13 On-Chip Frame Buffer Size
This field is used to select the onboard VGA’s frame buffer size that
is shared from the system memory.
