General protection interrupt.

Occurs on:  286 only.  This is an Abend error.

Meaning:  This is interrupt 13 in the 286 CPU and it is generated by the
          CPU when memory protection violations occur that are not
          specifically handled by interrupts 9-12.  For example,
          attempting to write to a segment that has been defined as
          read-only will generate this interrupt. This interrupt should
          never occur in NetWare and will generate a fatal abend error.
          This error usually indicates that the CPU's registers and/or
          the file server's memory has been severely altered.

Cause:  This error can be caused by just about anything including both
        hardware and software.  The most probable cause of such an error
        would be a memory failure in the file server attributable to
        either a hardware failure or poor power line conditioning.  A
        corrupt operating system file might also cause this error.  On
        older 286 systems with early versions of NetWare, this error
        would occur when the file server's memory was over 4 MB or when
        the cache block size was set to under 4096.

Solution:  Reboot the file server.  If this error or other interrupt
           errors occur repeatedly, reinstall the operating system and
           then check the file server's memory and power line
           conditioning.  Attempt to narrow the problem down to hardware
           or software.  Try replacing the interface cards, adding more
           memory, slowing the clock rate down, or reconfiguring the
           operating system.

    On older systems, decrease the amount of memory in the file server
    to a level below 4 MB and/or increase the cache block size to at
    least 4096 using the INSTALL utility.  If neither of these work, you
    may need to upgrade the operating system.
