            ********** Release History **********


**************************************************************
Release 1.3                                  February 19, 1998
**************************************************************

This driver is for the Motorola PowerPC 860 / 821.
The boards it works on are the Motorola PowerPC ADS, the MBX and
the Embedded Support Tools (EST) SBC8XX board.


There are three batch files that correspond to each of the three 
supported boards.

    abldnet.bat   -   builds the NET library for ADS board
    mbldnet.bat   -   builds the NET library for MBX board
    ebldnet.bat   -   builds the NET library for EST board

These files are all the same with the exception of the line that
builds the pquicc.c file.
Abldnet.bat has a switch -DADS, to let the pquicc.c module
know the to use the ADS specific configuration.

The driver copies the packets to memory at 0x38000.
If you look at the two pragmas in the file pquicc.c, and the user_mmu.c,
and the demo.lnk.  You can see how the variable is assigned to a section,
that section is documented with the mmu code, and the demo.lnk places it
in physical memory.

The driver uses the CPM Dual Port Ram to store the buffer descriptors.
There are ten receive descriptors and ten transmit descriptors.
The descriptors start at IMMR + 0x2000.

The driver is associated with the kernel with the NU_Register_LISR 
call around line 895 of pquicc.c.

NU_Etopen is where the initialization of the CPM occurs so that the CPM
will do ethernet.  Please review the settings in the NU_Etopen function
to make sure they are specific for your situation.  For example, you can
set the controller in promiscuous mode or normal mode in this function.
The default is normal mode.
