-------------------------------------------------
multiprocessor system
---------------------

3Com has observed that the 3Com EtherLink 10/100 PCI NIC may
not install on a multiprocessor system which has only been
populated with one processor. This problem was observed on
Windows 2000 only and the build was (2072) Release Candidate 1.
If the problem occurs please consult Microsoft.

TCP Segmentation offloads
-------------------------
Although the 3Com EtherLink 10/100 PCI NIC with 3XP Processor
can process large send offloads (LSO) from the Windows 2000
operating system(s), the released version(s) of Windows 2000
has this feature disabled by default.
802.1p Windows 2000 Advanced Tab offloads
-----------------------------------------
802.1p traffic prioritization offloads are possible from the
Windows 2000 operating system and can be turned on/off for
the 3CR990 NIC's however, setting traffic priority for applications
in Windows 2000 must be done from through Windows 2000.

After performing an upgrade to Windows 2000 from either Windows 95,
Windows 98 or Windows NT 4.0, the 3CR990 windows diagnostics utility
must be reinstalled. This can be done with the shipping driver CD by using
installation utility.
