H165128:  SCO 5.0.5 & IBM PCI T/R ADAPTER SHARING INTERRUPTS


 SYMPTOM:

 During installation of SCO 5.0.5, if 2 or more IBM PCI Token
 Ring adapters (41H8900) are installed with the token ring
 adapters sharing interrupts, there will be errors during the
 SCO installation. The system needs to be rebooted and the
 installation re-started. If SCO 5.0.5 is already installed and
 2 or more token ring adapters are added, the system will hang
 as the OS is loaded if the adapters share the same interrupt.

 PROBLEM ISOLATION AIDS:

 - The system is a Netfinity 5000 server, Type 8659, any Model.

 - The system is being configured with SCO 5.0.5.

 - The system has two (2) or more IBM PCI Token Ring adapters
   (41H8900).

 - The IBM PCI Token Ring adapters are sharing interrupts.

 - The installation of the OS errors.

 FIX:

 Ensure the token ring adapters do not share the same interrupt.
