Software • BIOS for System Unit with Socket 370
CPU Internal Cache
Switching the L1 cache of the processor, on or off. Switching off the internal cache
slows down the system considerably, and therefore is not advisable.
External Cache
Makes possible to prevent the use of the integrated L2 cache on the mainboard.
Switching off the internal cache slows down the system considerably, and is
therefore not advisable.
CPU L2 Cache ECC Checking
With the Error Correction Code individual faulty Bits are automatically corrected
when reading/writing the L2 cache memory.
Processor Number Feature
This option, which checks the access to the serial number of the processor, is
available with processors based on the Coppermine core (e.g. Celeron 566/66,
Pentium III 600/100). If the parameter is set to Enabled, other programs (e.g.
Microsoft Internet Explorer 4.0) can be accessed and forwarded.
Quick Power On Self Test
When Enabled POST speeds up (no detailed memory test).
Boot From LAN First
Before a specified device of an operating system is searched for using a "Boot
Sequence", BIOS attempts to boot from a device connected to the network.
Boot Sequence
Determines the order in which to boot the respective devices, offering different
combination options.
At the beginning of the sequence, an operating system is sought on the first
device. If there is none found, BIOS searches for the next device etc. If an
operating system is found on a device then this drive is booted. However, if BIOS
does not find an operating system an error message then appears on the screen.
If there is no hard disk on the drive which was finally booted, then it is
automatically assigned drive designation A. If an additional disk drive is available,
then it is automatically assigned the drive designation B.
