BIOS Setup
Internal Cache/External Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting controls the internal cache (also known as L1
or level 1 cache) or the external cache (also known as L2 or level 2 cache).
Setting options: Disabled, WriteBack, Write Thru. WriteBack & WriteThru
refer to the cache’s write policy, which determines how it handles writes to
memory locations that are currently being held in cache. The WriteBack
cachelpolicy will produce the best performance.
APIC Select
This field is used to enable or disable the APIC (Advanced Programmable
Interrupt Controller). Due to compliance to PC2001 design guide, the system is
able to run in APIC mode. Enabling APIC mode will expand available IRQs
resources for the system. Settings: Enabled, Disabled.
MPS Revision
This field allows you to select which MPS (Multi-Processor Specification)
version to be used for the operating system. You need to select the MPS
version supported by your operating system. To find out which version to use,
consult the vendor of your operating system. Settings: 1.4, 1.1.
