BIOS SETUP
•
Resource Controlled by
The Award Plug and Play BIOS can automatically configure all the boot and Plug and Play(PnP)
compatible devices. If you select “Auto”, all the interrupt request (IRQ) and DMA assignment
fields disappear, as the BIOS automatically assigns them.
The choice: Auto and Manual.
•
Reset Configuration Data
Normally, you leave this field “Disabled”. Select “Enabled” to reset Extended System
Configuration Data (ESCD) when you exit “Setup”, if you have installed a new add-on and
the system reconfiguration has caused such a serious conflict that the operating
system cannot boot.
•
IRQ-n Assigned to
When resources are controlled manually, assign each system interrupt as one of the follow-
ing types, depending on the type of device using the interrupt.
- Legacy ISA Devices, requiring a specific interrupt (such as IRQ4 for serial port1), compli-
ant with the original PC AT bus specification.
- PCI/ISA PnP devices, whether designed for PCI or ISA bus architecture, compliant with
the Plug and Play standard.
•
DMA n Assigned to
When resources are controlled manually, assign each system DMA channel as one of the
following types, depending on the type of device using the DMA.
- Legacy ISA Devices, requiring a specific DMA channel, compliant with the original PC
AT bus specification,
- PCI/ISA PnP devices, whether designed for PCI or ISA bus architecture, compliant with
the Plug and Play standard.
•
PCI 1,2,3,4 Use IRQ No.
These fields set how IRQ use is determined for each PCI slot. The default setting for each
field is “Auto”, which uses auto-routing to determine IRQ used. The other options are manual
settings of NA, 5, 7, 9, 10, 11, 12, 14 or 15 for each slot.
•
Used MEM Base Addr
This field allows you to set the base address and block size of a legacy ISA card that uses
any memory segment within the C800H and DFFFH address range. If you have more than
one legacy ISA card in your system that requires to use this address range, you can increase
the block size to either 8K, 16K, 32K or 64K.
