Chapter 3 AWARD BIOS USER’S GUIDE
Resources Controlled By
By Choosing “Auto” the system BIOS will detect the system
resource and automatically assign the relative IRQ and DMA
Channel for each peripheral.
Note: There are limitations to this function. For example when choosing
“Auto” you must be sure that all of the system add-on cards are PnP type.
By Choosing “Manual”(default), the user will need to assign
IRQ & DMA for add-on cards. Be sure that there is no conflict
IRQ/DMA and I/O ports.
Reset Configuration Data
The system BIOS supports the PnP feature so the system needs to
record which resource is assigned and protect 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
automatically when the new configuration varies from the last one.
If Enabled is chosen the system will be forced to update ESCDs if the
system configuration has changed and then auto set this option to the
“Disabled” mode.
