BIOS Setup
2-28
PNP OS Installed
When set to YES, BIOS will only initialize the PnP cards used for booting
(VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP
operating systems, like Windows
TM
95. When set to NO, BIOS will
initialize all the PnP cards. Therefore for non-PnP operating system
(DOS, Netware
TM
), this option must set to “NO”.
Reset Configuration Data
The system BIOS supports the PnP feature so the system needs to record which
resource is assigned and proceeds resources from conflict. Every peripheral
device has a node, which is called ESCD. This node records which resources
are assigned to it. The system needs to record and update ESCD to the memory
locations. These locations (4K) are reserved at the system BIOS.
If Disabled (default) is chosen, the system’s ESCD will update only when the new
configuration varies from the last one.
If Enabled is chosen, the system is forced to update ESCDs and then is
automatically set to the “Disabled” mode.

Legacy is the term, which signifies that a resource is assigned to the ISA Bus and
