Setting System Parameters 4-11
System Cache
The default for the System Cache field is “Enabled.” This
field controls both the primary and secondary caches.
Setting the system cache to “Disabled” will hurt
performance, but might be required when running software
which utilizes software timing loops and needs to be slowed
down to execute properly.
Boot Speed
Boot speed refers to the system CPU cycles. The default
boot speed is “Turbo.” “De-turbo” mode slows the CPU by
disabling the system cache and adding increased refresh
cycles.
NOTE
“De-turbo
”
does not reduce the CPU speed to
8 MHz. If
“
De-turbo
”
is selected it will automatically
“
Disable
”
the System Cache.
Num Lock
The Num Lock field controls whether the Num Lock key on
the keyboard will be “On” or “Off” at bootup. The default
is “On.”
Setup Prompt
The Setup Prompt field allows you to disable the “Press
<F1> Key To Enter Setup” message displayed during
POST. It does not control access, just the message. This
field can be either “Enabled” or “Disabled.” The default is
“Enabled.”
