Message 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 adapters, see “Adapter Configuration” on page 69.
For information about required DMA resource settings for
ISA legacy adapters, see the documentation supplied with
these adapters. For more information, see Chapter 5, “Using
the Configuration/Setup Utility Program” on page 29.
2. Make sure that switches on all ISA legacy adapters are set
correctly. For information about switch settings, see the
documentation supplied 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
“Working with Adapters” on page 68.
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 corrected, have the computer serviced.
