DMA 0/1/3/5/6/7 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 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 settings are Legacy ISA or
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. Under all circumstances, you should
retain the default configuration unless advised otherwise by your system’s
manufacturer. The settings are Level or Edge.
PCI IDE 2nd Channel
The IDE standard supports two channels (interfaces) with two
devices on each channel. Enable the second channel if your system has two
PCI IDE connectors in use, either on the system board or on expansion
boards. Disable the second channel if a second IDE connector is not
present or not in use. The settings are Enabled or Disabled.
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 settings 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.
Selecting “PCI Auto” allows the system to automatically determine
how your IDE disk system is configured.
