The tray icon doesn't appear under HPC2000.
With all 3Com 589 series adapters the NIC has to be set in EPROM on the moded it is using, the things cannot auto select like on the PC.
The tools for that are in the 3Com redist in their downloads area.
I was sent the bits by a user, they are based around a 3Com beta driver, and they suspended work on it completly. All modifications made to get it to work under HPC2000 are registry and settings based.
The only way to fix it would be to decompile it
(disclaimer: I'm not suggesting anyone decompile it as that would be illegal. It's a matter of fact statement
).

Secondly, when I was actively working on trying to improve the driver for people, only 3 people of roughly 300 who downloaded it while it was in beta bothered to let me know the results they were seeing. The 3 reported it was OK.
The people who couldn't be bothered to send in their experiences only contacted me after I released it to moan and grip about things not working. After which one has no incentive to even humour them.
I made a news post, stating my position - as above - and now have no wish to continue.

Any way, jear jerkers aside. It's worth investigating the state of the EPROM, reset it to default values and set the transfer mode manually. Don't enable full duplex either.
