boot and Plug and Play-compatible devices. If you select Auto, all
the interrupt request (IRQ), DMA assignment, and Used DMA fields
disappear, as the BIOS automatically assigns them. The default
value is
“Manual” .
z IRQ Resources
When resources are controlled manually, assign each system
interrupt as one of the following types, depending on the type of
device using the interrupt:
1. Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific interrupt (such as IRQ4 for serial port
1).
2. PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
The default value is “PCI/ISA PnP” .
z DMA Resources
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:
1.
Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific DMA channel.
2.
PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
The default value is “PCI/ISA PnP” .
z PCI/VGA Palette Snoop
Some non-standard VGA display cards may not show colors
properly. This field allows you to set whether MPEG ISA/VESA
VGA Cards can work with PCI/VGA or not. When enabled, a
PCI/VGA can work with a MPEG ISA/VESA VGA card. When
disabled, a PCI/VGA cannot work with a MPEG ISA/VESA Card.
z Assign IRQ For VGA
The Enabled item allows the BIOS to auto-route an IRQ for use by
a VGA card.
z Assign IRQ For USB
It enables or disables IRQ allocation for the USB (Universal Serial
Bus). Enable this if you are using a USB device.
