System BIOS Cacheable
When this option is set to Enabled, the contents of the F0000h system memory
segment can be read from or written to L2 secondary cache memory. The
contents of the F0000h memory segment are always copied from the BIOS
ROM to system RAM for faster execution. The settings are Enabled or
Disabled. The Optimal default setting is Enabled. The Fail – Safe default setting
is Disabled.
Caching Controller
Set this option to Present if a cache controller is installed in the computer. The
Optimal and Fail – Safe default settings are Absent.
Setting
Absent To comply with the PCI specifications, PCI adapter cards must be
reset every time the CPU is reset. When the end user forces a soft
reset by pressing <Ctrl> <Alt> <Del>, only the CPU is reset. When
this option is set to No, all soft resets are converted to hard resets,
and all PCI adapter cards are reset when the CPU is reset.
Present Soft resets still behave like soft resets when Present is selected.
Select this option if a caching controller is installed in the computer.
Soft resets must not generate a hard reset if a caching controller is
used. If a hard reset is generated, a PCI caching controller card may
not be able to flush data from its cache memory to a hard disk drive
before the reset.
