Description
1886 A Plug and Play adapter has requested a DMA address that is not available.
Action:
1. Make sure that all ISA legacy adapters are set correctly in the
Configuration/Setup Utility program. If the DMA address settings are not
correct, change and save the settings. Setting the resources used by ISA
legacy adapters to ISA Resource enables the Plug and Play function to
configure around the legacy adapters.
For background information on PCI, ISA, Plug and Play, and legacy
(non-Plug and Play) adapters, refer to Chapter 5, “Installing options” on
page 67. For information about required DMA resource settings for ISA
legacy adapters, refer to the documentation that comes with these adapters.
For instructions on using the Configuration/Setup Utility program, see
Chapter 3, “Using the Configuration/Setup Utility Program” on page 17.
2. Make sure that switches on all ISA legacy adapters are set correctly. For
information about switch settings, refer to the documentation that comes
with the ISA legacy adapters.
3. If all DMA addresses are being used by ISA legacy adapters, you might
need to remove an ISA legacy adapter to make a DMA address available to
the Plug and Play adapter you want to install. For instructions on
removing adapters, see Chapter 5, “Installing options” on page 67.
Note: If you remove an ISA legacy adapter, set the DMA address used by
the removed adapter to Available before installing another adapter.
4. If you have other PCI or Plug and Play adapters installed, you might need
to remove one of these adapters to make a DMA address available to the
Plug and Play adapter you want to install.
If the problem cannot be isolated and corrected, have the computer serviced.
