Introduction of BIOS 3-29
Resources Controlled By:
When resource 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 devices compliant with the Plug and Play standard, whether designed
for PCI or ISA bus architecture.
Two options are available: Auto or Manual. The Award Plug and Play BIOS
has the capability to automatically configure all of 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.
But if you have trouble in assigning the interrupt resource automatically, you
can select Manual to set which IRQ and DMA are assigned to PCI/ISA PnP or
legacy ISA cards.
Assign IRQ For VGA :
You can assign an IRQ for the PCI VGA or Auto.
Assign IRQ For USB:
If you need another IRQ to be freed up, you can choose to disable this item,
and you can get an IRQ. But in some situations in Windows
®
95 it may cause
the USB port to malfunction or other problems! Two options are available:
Enable or Disable the assigned IRQ action.
PIRQ_1 Use IRQ No. ~ PIRQ_4 Use IRQ No:
This item allows you to specify the IRQ number for the device installed on
PCI slots. Which means, you can specific the fixed IRQ number for the device
installed on the PCI slots (PCI slot 1 to PCI slot 5, included AGP slot). This is
a useful function when you want to fix the IRQ for a specific device.
For example, if you want to remove your hard disk to another computer and
don’t want to re-install the Windows
®
NT 4.0 (and lower versions), then you
can specific the IRQ for device install on the new computer to fit original
computer settings.
