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.
The choices: Enabled, Disabled.
CPU L2 Cache ECC Checking
When you select Enabled, memory checking is enable when the
external cache contains ECC SRAMs.
The choices:Enabled, Disabled.
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.
The choices: Enabled, Disabled.
First/Second/Third Boot Device
The BIOS attempts to load the operating system from the devices
in the sequence selected in these items.
The choices: Floppy, LS120, HDD0, HDD1, HDD2, HDD3, SCSI,
CDROM, LAN, Disabled.
