POST Message 1886 Description 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 67. 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 27. 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 66. 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. Chapter 8. Troubleshooting 103
