Since about my third post on the subject, the "primary test client" has
been Fedore Core 4. The server is Fedora Core 5. I decided to remove
the Win32 variable early on. I'm digging into the R8169 adapter on the
server to see if there are firmware issues on that card. I found the
latest firmware and download utility on their web site cleverly hidden
under DOS.
Since the weekend is coming up and I can spare a few minutes of down
time, I may attempt to move the tape server to another machine. I'll
probably reflash the firmware tomorrow, test once, then move the tapes
to another server if it fails.
