POST Messages POST Message 1850 Description A Plug and Play adapter has requested a hardware interrupt that is not available. Action: 1. Make sure that all ISA legacy adapters and all other adapters are set correctly 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 information about PCI and ISA adapters, see "Working with Adapters" on page 59. For information about Plug and Play and legacy (non-Plug and Play) adapters, see "ISA Legacy Resources" on page 40. For information about the required interrupt resource settings for ISA adapters, refer to the documentation that comes with these adapters. For information on using the Configuration/Setup Utility program, see "Using the Configuration/Setup Utility Program" on page 28. 2. Make sure that the 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 that you want to install. For information on removing adapters, see "Installing or Removing Adapters" on page 61. For information on setting resources, see "ISA Legacy Resources" on page 40. 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 that you want to install. If the problem cannot be isolated and corrected, have the system serviced. 142 Netfinity 3500 User's Handbook
