3.5.1 System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-
FFFFFh, resulting in better system performance.  However, if any pro-
gram writes to this memory area, a system error may result.  The choice:  
Enabled, Disabled.
3.5.2 Memory Auto Precharge
The options for this setting are Enabled and Disabled. When enabled, an 
Auto Precharge for read/writes based on speculative algorithms is per-
formed.
