INSTALLATION INSTRUCTIONS:

To install the patch.  Replace the NBI.NLM file located in the startup
directory (typically C:\NWSERVER), with the NBI.NLM specific to your servers
version of NetWare.  (The \NW51 directory contains the NBI.NLM for NetWare 5.1;
\NW6 directory contains the NBI.NLM for NetWare 6.0)

ISSUE: 

These files are intended to support specific IBM systems with PCI expansion
chassis installed.  They contain a fix to support the large number of entries
in the PCI IRQ route table that would be present on these particular systems.

These versions of NBI.NLM are identical to those posted in NW5.1 Support Pack 6
and post NW6.0 Support Pack 3. These files are needed in order to support some
new IBM hardware models and are provided here for convenience sake.

Other Issues addressed with these files:

1.	Made changes to mouse.c to allow the poll_aux_status to be able to sleep.

2.	Altered Search Adapter for PCI to use information obtained from DoScan
instead of going through bios calls.  The IDEATA driver is now HIN aware and
needs to find hardware that the BIOS FIND_PCI_DEVICE is not reporting.

3.	Fixed abend issue related to search adapter changes.  Some hardware
platforms modify the "scansequence" value.  Since search adapter is now passing
back a pointer instead of an index an abend occurs when referencing memory that
is not mapped in.

4.	Fixed an abend due to spinlock being held on a single processor.  A driver
is accessing configuration space at the same time that hwdetect is trying to
determine the devices in the system.

5.	Fixed non load issue for disk driver.  Expecting a NBI_ITEM_NOT_PRESENT
instead of NBI_NO_MORE_ITEMS coming back from search adapter.

6.	Fixed a call to OldSearchAdapter from searchadapter to pass in the correct 
	number of parameters.  Had left off the productID parmeter.
	
7.	Removed detection of mouse code and VGA code. This resolves CPUHog abends
which may occur on some hardware platforms because of hardware delays in
polling the mouse port.
