The system operates faster. When set to Non-cacheable,
it lets the system BIOS run from RAM.
If the Video BIOS parameter is set to Enabled, you may
select Cacheable or Non-cacheable for the C0000h-
C7FFFh parameter. When set to Cacheable, it allows the
video BIOS to run directly from the cache memory. The
system operates faster. When set to Non-cacheable, it
lets the video BIOS run from RAM.
With this parameter set to Enabled, the system
guarantees that the ISA 2.1 microseconds CHRDY
specification is not violated. This is crucial for some
timing-critical expansion boards. Note that enabling this
parameter slightly decreases the concurrency of PCI bus
and EISA bus.
This parameter allows PCI bus arbitration to decide
which master device supported by the bus can own it at
a specific time.
There are basically two arbitration modes for PCI bus
masters:
•
Fixed – can be CPU or EISA/IO. The CPU and
EISA/IO are the two possible highest priority
devices. When set to either of these options, and
there is more than one device requesting the bus, the
master device obtains the bus according to its fixed
priorities.
