Description
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.
Soft resets still behave like soft resets when Yes 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 cannot flush data from cache memory
to a hard disk drive before the reset.
