Changes in v1.08:
-Fixed the unrecognized-NIC problem by hotplug application
 after system startup.

Changes in v1.07:

Changes in v1.06:
-Recompiled to use the latest BMAPI.DLL.

Changes in v1.05:
-Reduced CPU utilization.  Fixed memory leak and service stop  
 problem. Utilized BMAPI event callback mechanism to refresh 
 LBFO team member states instead of polling.

Changes in v1.04:
-Fixed the LBFO team member state information not being refreshed
 after a hot swap of a member as that member was selected at the
 end of the hot swap process to rejoin the team as the primary 
 member of the LBFO team.

Changes in v1.02:
-Fixed Broadcom LBFO team member NICs state update to allow hot swap
 of the inactive card in the event that the card has been failovered 
 due to transmit/receive failures.


Changes in v1.01:
-Supports non failover member NIC card hot swap.

-FLB status is polled.

 ----------------------------------------------------------------------
-The Broadcom DMI PCI Hot Plug feature requires the Broadcom Management
 Application Program Interface (BMAPI) be installed to work properly.
 This file should be installed in the target system's System32 directory.
 Look for the presence of the file bmapi.dll.

-Requires IBM Hot Plug Services v4.2 or newer to ensure proper operations.
 This version contains important bug fixes to galvanize proper hot plug
 operations.  This version can be downloaded from the IBM website:
 "www-1.ibm.com/servlet/support/manager?rs=0&rt=0&org=psg&doc=MIGR-4BLKLS"
 or can be located through the IBM website search on "Hot Plug Services for
 Windows NT 4".
   
-Requires the existence of the DMI Service Provider software 
 v2.0 from Smart Technology Enabler or Intel in the target 
 system for the DMI PCI Hot Plug Service to work.

-DMI Service Provider software v2.0 has to be installed prior to the
 installation of the Broadcom DMI PCI Hot Plug Service.

-The b57dmihp.mif file should be installed where the OEM DMI management
 software is installed.  Typically, the DMI Management software is installed
 in \Program Files\OEM directory.  The b57dmihp.mif should be installed 
 into Program Files\OEM\DMI\Win32\mifs
 directory.

 The following files are installed from the OEM Hot Plug Software
 Kit.  These Files have to be installed in the target system's 
 Windows NT4.0 System32 directory after the installation of the Hot Plug
 application software.

 hotplug.sys
 swapdmi.dll
 nssevlog.dll
 nssrv.exe
 nssrv.mif
 swaplog.dll
 hotdmi.dll
 hotevlog.dll
 hotevent.exe
 hotplugc.cpl
 hotsrv.exe
 hotsrv.dll
 hotpnp.exe
 hotplug.mif
 
 The following files are installed from the OEM Hot Plug Software
 Kit.  These Files have to be installed in the target system's OEM 
 Hot Plug PCI product directory.  I.e. in Dell system, these files 
 are typically located in 
 \Program Files\Dell Computer Corporation\Dell PCI Hot Plug Services
 if default installation path was selected during installation 
 of the Hot Plug application software.

 hotswap.exe
 hotdevs.ini
 hotplug.hlp
 hotplug.cnt

-Hot Add feature is not fully tested.  Installation of a new 
 BCM5700 NIC does not launch the Control Panel's Network NIC Adapter
 installation screen.  This problem is due to the test target system's
 inability to stablize the power-on sequence on the newly seated NIC
 on the PCI slot.  The test target system's PCI slot green LED remains
 flashing after being pushed.  This LED should be on constantly to 
 signal that the new NIC has been powered on properly. 

-Hot Add for Windows NT4.0 is not supported in the Dell servers.
