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 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.
The choice: Legacy ISA, PCI/ISA PnP.
• PCI IRQ Activated by:
This sets the method by which the PCI bus recognizes that an IRQ service is being
requested by a device.
configuration unless advised otherwise by your system's manufacturer.
The choice: Level, Edge.
• PCI IDE IRQ Map to:
This allows you to configure your system to the type of IDE disk controller in use. By
default, Setup assumes that your controller is an ISA (Industry Standard Architecture)
device rather than a PCI controller. The more apparent difference is the type of slot
being used.
If you have equipped your system with a PCI controller, changing this allows you to
specify which slot has the controller and which PCI interrupt (A, B,C or D) is associated
with the connected hard drives.
Remember that this setting refers to the hard disk drive itself, rather than individual
partitions. Since each IDE controller supports two separate hard drives, you can select
the INT# for each. Again, you will note that the primary has a lower interrupt than the
secondary as described in "Slot x Using INT#" above.
Selecting "PCI Auto" allows the system to automatically determine how your IDE disk
system is configured.
3-6 LOAD BIOS DEFAULTS
The "LOAD BIOS DEFAULTS" function loads the system default data directly from ROM
and initialize associated hardware properly. This function will be necessary only when
the system CMOS data is corrupted.
