POST Message 1803 1804 1805 Description A PCI adapter has requested a memory address that is not available, or the PCI adapter might be defective. Action: 1. Make sure that settings for all ISA legacy adapters are correct in the Configuration/Setup Utility Program. If the memory address settings are not correct, change and save the settings. Setting the resources used by ISA legacy adapters to Not available 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 memory 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 4, "Configuring Your Computer" on page 39. 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 memory addresses are being used by ISA legacy adapters, you might need to remove an ISA legacy adapter to make a memory address available to the PCI 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 memory 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 memory address available to the PCI adapter you want to install. If the problem cannot be isolated and corrected, have the computer serviced. A PCI adapter read-only memory (ROM) error occurred. Action: Remove all of the PCI adapters that are not required for system startup and reinstall them one at a time, retesting after each is reinstalled. When an adapter fails, replace it. If the problem cannot be isolated and corrected, have the computer serviced. Chapter 6. Solving Problems 79
