2-16 Technical Information
Advanced Menu
Selecting “Advanced” from the Main menu displays a menu with the following options.
PnP O/S
The PnP field indicates if the computer’s operating system is configured to use Plug and
Play devices. Choose “Yes” if you are using a system that has Plug and Play. The default is
“Yes” for Windows 95 systems. For systems without Plug and Play (such as Windows NT
4.0), this field is set to “No.”
Reset Configuration Data
Use this setting to clear CMOS (by selecting “Yes” and rebooting) if the system parameters
get corrupted. The default is “No.”
Memory Cache
Memory cache saves time for the CPU by holding data most recently accessed in regular
memory (dynamic RAM or DRAM) in a special storage area of static RAM (SRAM), which
is faster. Before accessing regular memory, the CPU first accesses the cache. If it does not
find the data it is looking for, it accesses the regular memory.
The default for the Memory Cache is “Enabled.” This field controls both the primary and
secondary caches. Setting the Memory Cache to “Disabled” will hurt performance, but
might be required when running programs that utilize software-timing loops and need to be
slowed down to execute properly.
Memory Banks 0 and 1
The two Memory Bank fields are read only. They display the total amount of memory in
each DIMM bank.
Resource Configuration
Memory Reservation
Use this field to reserve specified blocks of upper memory for use by other ISA
devices. Select “Reserved” to choose a memory block. The default for each block
is “Available.”
The following list includes the available memory blocks:
C800-CBFF
CC00-CFFF
D000-D3FF
D400-D7FF
D800-DBFF
