POST Messages POST message 1802 Description A PCI adapter has requested an I/O address that is not available, or the PCI adapter might be defective. Action: 1. Make sure that all ISA legacy adapters and all other adapters are set correctly in the Configuration/Setup Utility program. If the I/O 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 I/O 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. If the I/O port resource settings are correct, the PCI adapter might be defective. Have the system serviced. 3. 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. 4. If all I/O addresses are being used by ISA legacy adapters, you might need to remove an ISA legacy adapter to make an I/O address available to the PCI 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 I/O address used by the removed adapter to Available before installing another adapter. 5. If you have other PCI or Plug and Play adapters installed, you might need to remove one of these adapters to make an I/O address available to the PCI adapter that you want to install. If the problem cannot be isolated and corrected, have the system serviced. Chapter 5. Solving problems 181
