1886 A Plug and Play adapter has requested a DMA address that is
not available.
Action:
1. Make sure that all ISA legacy adapters and all other 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 information about PCI and ISA adapters, see “Working
with adapters” on page 79. For information about Plug and
Play and legacy (non-Plug and Play) adapters, see “ISA
Legacy Resources” on page 55. For information about the
required memory resource settings for ISA adapters, refer to
the documentation that comes with these adapters. For
information on using the Configuration/Setup Utility
program, see “Using the Configuration/Setup Utility
program” on page 39.
2. Make sure that the 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 that you
want to install. For information on removing adapters, see
“Installing or removing ISA and PCI adapters” on page 82.
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
memory available to the Plug and Play adapter that you
want to install.
If the problem cannot be isolated and corrected, have the system
serviced.
