POST Message Description

1856 A Plug and Play adapter has requested a DMA address that is not

available.

Action:

1. Make sure that all ISA legacy adapters are set correctly in the

Configuration/Setup Utility program. If the DMA 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

DMA 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 DMA addresses are being used by ISA legacy adapters,

you might need to remove an ISA legacy adapter to make a

DMA 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 DMA

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 DMA

address available to the Plug and Play adapter you want to

install.

If the problem cannot be isolated and corrected, have the computer

serviced.
