users only

 

 

entering the setup password.

 

 

 

 

• Limit CPUID Maximum Value to 3 - Restricts the number of

 

 

CPUID functions reported by the microprocessor. Enable this

 

 

feature if booting to WinNT.

 

 

• ACPI/USB Buffers @ Top of Memory (enable/disable).

 

 

Enabling this feature places USB memory buffers at the top

 

 

of memory. The advantage is that some amount of memory

 

 

below 1 MB is freed up for use by option ROMs. The

 

 

disadvantage is that a popular memory manager, HIMEM.SYS,

 

 

does not work properly when USB buffers are at top of memory

 

 

AND the system has 64 MB or less of RAM.
