System BIOS Cacheable
When this option is enabled, accesses to the system BIOS ROM
addressed at F0000H-FFFFFH are cached, provided that the cache
controller is enabled. The larger the range of the Cache RAM, the higher
the efficiency of the system.
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.
Video RAM Cacheable
When enabled, it allows the video RAM to be cacheable thus providing
better video performance. If your graphics card does not support this
function, leave this field in its default setting - Disabled.
8 Bit I/O Recovery Time and 16 Bit I/O Recovery Time
The recovery time is the length of time, measured in SYSCLK, which
the system will delay after the completion of an input/output request.
This delay takes place because the CPU is operating so much faster
than the input/output bus that the CPU must be delayed to allow for
the completion of the I/O. This item allows you to determine the
recovery time allowed for 8-bit I/O or 16-bit I/O.
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 option must be
disabled to provide contiguous system memory.
