POST Message 1880 Description A Plug and Play adapter has requested a hardware interrupt that is not available. Action: 1. Make sure that settings for all ISA legacy adapters are correct in the Configuration/Setup Utility program. If the hardware interrupt 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 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 interrupt 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 Chapter 5, "Using the Configuration/Setup Utility program" on page 61. 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 hardware interrupts are being used by ISA legacy adapters, you might need to remove an ISA legacy adapter to make an interrupt 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 hardware interrupt 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 interrupt available to the Plug and Play adapter you want to install. 5. If your system will be loading a Plug and Play operating system, ensure that Plug and Play Operating System is set to Yes. 6. Ensure that the address decode value for the adapter is properly set. If the problem cannot be isolated and corrected, have the computer serviced. 118 Using Your Personal Computer

Description
1880
A Plug and Play adapter has requested a hardware interrupt that is not
available.
Action:
1.
Make sure that settings for all ISA legacy adapters are correct in the
Configuration/Setup Utility program.
If the hardware interrupt
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 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 interrupt 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 Chapter
5, “Using the Configuration/Setup Utility
program” on page
61.
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 hardware interrupts are being used by ISA legacy adapters, you
might need to remove an ISA legacy adapter to make an interrupt
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 hardware interrupt
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 interrupt available to
the Plug and Play adapter you want to install.
5.
If your system will be loading a Plug and Play operating system,
ensure that Plug and Play Operating System is set to
Yes
.
6.
Ensure that the address decode value for the adapter is properly set.
If the problem cannot be isolated and corrected, have the computer
serviced.
