H165145:  FREE IRQ'S ON 320, 520, AND 330'S, FOR PCI DEVICES


 TEXT:

 Free IRQ's on 320, 520, and 330's, for PCI Devices.

 SYMPTOMS:

 Customer has used up  interrupts: 2/9, 10, 11, 15. Based on the
 Page 203, in the 320 users handbook  the customer attempts to
 free up more interrupts: - "if a situation occurs where you
 need an additional interrupt, you can use an interrupt from
 another function that you might not need, such as the IDE
 controller (interrupt 14) or COM port (interrupt 3)." The PCI
 device add to the system will be set to disabled in the EISA
 configuration.  The addition interrupts freed by the customer
 will not be available under the PCI device's resources. The
 customer may try to manually enable the adapter in the EISA
 utility, but will receive a message stating:" In order to
 accommodate your selection, the utility must make the following
 changes" At this time the utility will state the enable device
 must be set to disable.

 PROBLEM ISOLATION AIDS:

 - The system is one of the following IBM servers:

   -  PC Server 320, Type 8640, Models 0xx, 1xx, 2xx, 3xx,
      Mxx, EEx or Zxx.

   -  PC Server 330, Type 8640, Models PB0 or PT0.

   -  PC Server 520, Type 8641, Models EEx or Mxx.

 - The system is configured with any type of EISA adapter.

 Fix:

 No fix. It is not possible to set any PCI device to an
 interrupt other than 2/9, 10, 11 and 15.

 WORKAROUND:

 If there is a EISA device using one of the four interrupts that
 are usable by the PCI Bus, then that device should be moved to
 another supported interrupt, thus allowing the PCI device access
 to the interrupt.

 DETAILS:

 Novell NetWare doesn't allow the use of interrupt 15, thus
 limiting the PCI devices to 2/9, 10, 11.
