CPU Speed
This option determines the speed used by the server each time you turn it on or reboot it:
♦
Fast
is the normal speed and causes the CPU to run at its rated speed.
♦
Slow
(equivalent to 8 MHz) is used to reduce the effective CPU speed to be compatible with some
speed-
dependent application programs.
If an application program does not run correctly at full speed, try disabling all caches or changing the CPU
speed to slow. Server performance will be severely degraded while operating in slow mode.
Large Drive Addressing
This option allows to select
standard
for IDE hard disk drives up to 528 MB. When using IDE drives
larger than 528 MB and MS-DOS or MS-Windows is the operating system, select
LBA convert
.
Select
standard
for all other operating systems.
HDD Data Transfer Method
This option lets you take advantage of new IDE hard disk drive technologies. Setting this option to
Auto
Optimum
allows the server’s BIOS to interrogate and automatically set up any installed IDE hard disk
drive for optimum performance.
Primary Cache
This option lets you enable or disable the microprocessor's internal (primary) cache. Enabling the cache
controller significantly improves server performance by reducing the average number of wait states seen by
the microprocessor.
However, in some instances disabling the primary cache is desired, for example, while using time-
dependent software. In this instance, the server can operate but not at full potential.
Secondary Cache
This option lets you enable or disable the server’s external (secondary) cache. Enabling the secondary
cache significantly improves server performance by reducing the average number of wait states seen by the
microprocessor.
However, in some instances, disabling the secondary cache is desired, for example, while using time-
dependent software. In this instance, the server can operate but not at full potential.
Also, this field can be set to either Write-Back or Write-Through mode.
NOTE
If there is no secondary cache installed, make sure this option is set to disabled.
