POST Messages POST Message 1804 1805 Description A PCI adapter has requested a memory address that is not available. Action: 1. Make sure that all ISA legacy adapters and all other adapters are set correctly 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 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 59. For information about Plug and Play and legacy (non-Plug and Play) adapters, see "ISA Legacy Resources" on page 40. For information about the required memory 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 28. 2. 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. 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 that you want to install. For information on removing adapters, see "Installing or Removing Adapters" on page 61. 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 memory available to the PCI adapter that you want to install. If the problem cannot be isolated and corrected, have the system serviced. A PCI adapter read-only memory (ROM) error occurred. Action: Remove all PCI adapters that are not required for system startup, and reinstall them one at a time, powering on after each is reinstalled. When message 1805 displays, replace the adapter that you just installed. If the problem cannot be isolated and corrected, have the system serviced. Chapter 5. Solving Problems 141

A PCI adapter has requested a memory address that is not
available.
Action:
1.
Make sure that all ISA legacy adapters and all other adapters
are set correctly 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
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
59.
For information about Plug and
Play and legacy (non-Plug and Play) adapters, see “ISA
Legacy Resources” on page
40.
For information about the
required memory 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
28.
2.
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.
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 that
you want to install.
For information on removing adapters,
see “Installing or Removing Adapters” on page
61.
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
memory available to the PCI adapter that you want to install.
If the problem cannot be isolated and corrected, have the system
