Though this is not a big problem, it has annoyed me long enough that I want to have it fixed.

Over the last 2 years I have worked with around 10 different PCs with BOINC on them.

My Host List shows I have had 32 Hosts, when at this moment only 3 are running. I would love to condense the ones I know are the same computer to just 1 entry.

If this is possible let me know. Thanks

Depends on which host list. If you mean the host list from BAM! then simply wait. Any host that has not contacted BAM! in three months will be deleted from the list.

If it's the stats list or the list at the projects, then you're out of luck. Sometimes the hosts can be merged at the project, but otherwise they will stay there forever.

Dang, thanks anyway. I'm way to lazy right now to go through the hassle. Thanks for your help.

Against my lazyness I went ahead and tried to merg as many hosts as possible in the individual projects.

The problem I now face is that when merging computers that I know are the same, I am told they are not eligable.

Over the years these computers have undergone OS, network, and some hardware changes but the CPU stays the same.

I already left thread on the boinc forum, but I know I can get more help here.

How can I combine hosts I know are the same when Im told they aren't eligable?

No way to do so
I'm not quite sure what is necessary to be regarded as "the same", sometimes even a BOINC update with a different naming of a puter will leave the identical one seperated forever.
In most projects you can delete the ones without WUs attached, it's the only solution for it in such cases.
