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.
CPU to PCI Wrtie Buffer
When enabled, up to four Dwords of data can be written to the PCI bus without interrupting the CPU.
When disabled, a write buffer is not used and the CPU read cycle will not be completed until the PCI bus
signals that it is ready to receive the data..
Choices are Enabled, Disabled.
PCI Dynamic Bursting
When Enabled, every write transaction goes to the write buffer. Burstable transactions then burst on the
PCI bus and nonburstable transactions don’t.
Choices are Enabled, Disabled.
PCI Master 0 WS Write
When Enabled, writes to the PCI bus are executed with zero wait states.
Choices are Enabled, Disabled.
