440BX/ZX AT AWARD BIOS SETUP
MAINBOARD
Resources Controlled by : ( default setting: "Manual")
The Award Plug and Play BIOS can automatically configure all the boot and Plug and
Play-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 : ( default setting: "Disabled")
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.
The choice: Enabled and Disabled.
IRQ# assigned to : ( default setting: "PCI/ISA PnP")
When resources are controlled manually, assign each system interrupt as one of the
following types, depending on the type of device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a
specific interrupt (such as IRQ4 for serial port 1).
PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for
PCI or ISA bus architecture.
DMA# assigned to : ( default setting: "PCI/ISA PnP")
When resources are controlled manually, assign each system DMA channel as one of
the following types, depending on the type of device using the interrupt:
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a
specific DMA channel
PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for
PCI or ISA bus architecture.
Assign IRQ For VGA/USB : ( default setting: "Enabled")
The system's IRQ signals are limited and sometimes you may feel like to some more
IRQ signals for your add-on cards. The system BIOS of this mainboard allows you to
disable the IRQ which is supposed to be connected to VGA and USB ports. When you
have choose to disable the IRQ on VGA or USB port, the IRQ on the related port will
be released and becomes available for other devices.
