L1 Cache
Cache me mory is additi onal memory th at is much faster than conve ntional
DRAM (system memory). When the CPU requests data, the syst em transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting enables/disables the internal cache (also known
as L1 or level 1 cache). Setting to Enabled will speed up the system performance.
Flash Protection
This function protects the BIOS from accidental corruption by unauthorized
users or computer viruses. When enabled, the BIOS' data cannot be changed
when attempting to update the BIOS with a Flash utility. To successfully up-
date the BIOS, you'l l need to disable this Flash Protectio n function. Setting
options: Disabled, Enabled.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this
memory area, a system error may result. Setting options: Enabled, Disabled.
