Setting Description
No
(the default
setting)
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.
Yes 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.
