POST Message Description
1886 A Plug and Play adapter has requested a DMA address that is not
available.
Action:
1. Make sure that settings for all ISA legacy adapters are correct 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 Installing Options in Your Personal
Computer. 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 5, “Using the Configuration/Setup Utility
program” on page 61.
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 Installing Options in Your
Personal Computer.
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.
5. If your system will be loading a Plug and Play operating system,
ensure that Plug and Play Operating System is set to Yes.
6. Ensure that the address decode value for the adapter is properly set.
If the problem cannot be isolated and corrected, have the computer
serviced.
