Title: PRO.SYS Patch For NetBIOS
Date: 2-2-88

Copyright 3Com Corporation, 1991.  All rights reserved.

This patch should help performance when running NetBIOS
applications on 3+ 1.2.1.

NOTE:  This applies only to NetBIOS applications and will have no
effect on 3+ or anything else and it may not show any perceivable
results.  In certain cases it has cleared up a problem and in any
case it can not do any harm if done right.

For 3+ release 1.2 a change was make to the ETH driver so that if
a NetBIOS packet arrived a direct jump was made to PRO to handle
the packet instead of having it percolate up in the queue.  The
problem is that this is not being done due to the 1.2.1
internal version number "3.0.1".  The reason for this is that the
ETH driver checks the ASCII version number in PRO to make sure
that it is GREATER than 3.0, not GREATER than or EQUAL.

This will be fixed in 1.3 but there a way to fix it now.  This
is for 3+ version 1.2.1 and pro.sys as of 1:33pm  7-23-87 and is
7264 bytes in size.  The version number inside is 3.0.1.

In the following anything after a ; is a comment not to be
entered.

1. debug pro.sys
2. d126              ;the first byte should be the A '0'
3. e 126 '1'         ;change it to an ASCII 1
4. d126              ;to make sure that it is now 31H
5. w                 ;Now write it back out
6. q                 ;end debug

That is all that is necessary for the fix.  Just reboot and it
will take effect.
