POST Message Description
1852 A Plug and Play adapter has requested an I/O address that is not
available, or the Plug and Play 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 “Configuring Your Computer” on page 22.
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 Plug and Play 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 Plug and Play adapter you want to
install.
If the problem cannot be isolated and corrected, have the computer
serviced.
