installed a new add-on and the system reconfiguration has caused such a
serious conflict that the operating system can not boot.
3.6.4 IRQ-xx 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.
If your ISA card is not PnP compatible and requires a special IRQ to
support its function, set the selected IRQ to “Legacy ISA”. This setting
informs the PnP BIOS to reserve the selected IRQ for the installed legacy
ISA card.
3.6.5 DMA-x 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.
If your ISA card is not PnP compatible and requires a special DMA
channel to support its function, set the selected DMA channel to “Legacy
ISA”. This setting informs the PnP BIOS to reserve the selected DMA
channel for the installed legacy ISA card.
3.6.6 CPU to PCI Write Buffer (Enabled)
When enabled, up to four D words 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..
