Cpu L2 Cache Ecc Checking; Quick Power On Self Test - Aaeon SBC-659P User Manual

CPU Internal Cache/External Cache
Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on up
contain internal cache memory, and most, but not all, modern PCs
have additional (external) cache 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 External Cache field may not appear if your system does not
have external cache memory.

CPU L2 Cache ECC Checking

When you select Enabled, memory checking is enable when the
external cache contains ECC SRAMs.
Processor Number Feature
This option is for Pentium III processor. During Enabled, this will
check the CPU Serial number. Disabled this option if you don't
want the system to know the serial number.

Quick Power On Self Test

Select Enabled to reduce the amount of time required to run the
power-on-self-test (POST). A quick POST skips certain steps. We
recommend that you normally disable quick POST. Better to find a
problem during POST than lose data during your work.
