POST Message Description
1802 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 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 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 I/O 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 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 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 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 I/O 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 an I/O address available
to the PCI adapter you want to install.
If the problem cannot be isolated and corrected, have the computer
serviced.
