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.
