Windows 95).
Resources Controlled By
The Plug and Play EliteBIOS 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, because the BIOS automatically
assigns them.
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 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 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
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.
PCI IDE IRQ Map to
This field lets you select PCI IDE IRQ mapping or PC AT (ISA) interrupts. If
your system does not have one or two PCI IDE connectors on the system
board, select values according to the type of IDE interface(s) installed in your
system (PCI or ISA). Standard ISA interrupts for IDE channels are IRQ14 for
primary and IRQ15 for secondary.
