1803 A PCI adapter  has requested a  memory 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  memory 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
memory 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 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  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  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 a
memory address available  to the PCI  adapter you want  to
install.
If the problem  cannot be isolated  and corrected, have  the computer
serviced.
