No, it's a per-card function. Each of your three cards can
be a busmaster. For some reason it appears that one of your
cards has been configured to not be a busmaster. Software
isn't keeping up and you get an underrun.
Perhaps. I'm not sure at what point in the PIO transfer the
transmit actually starts...

No easy way, I'm afraid. I did it once by mangling Donald's
vortex-diag tool, but it wasn't pretty.
You just need a dos floppy.... freedos may suit. I don't
know - the only time I tried to use the 3com app, it went
silly and didn't work. Some user interface problem. :(
