I want to create dual-boot system Vista x86/Server 2008 x64.
If I will place BOINCData folder on common drive for these 2 OSes and will use 2 different BOINC program folders (and x86 /x64 BOINC binaries) - is it possible to maintain the same tasks set (via common BOINCData folder) for both OSes ?

I want to create dual-boot system Vista x86/Server 2008 x64.

I've not actually tested it, but I think that it should be OK.

You may have poblems, though, for those (very few) projects which automatically download 64-bit project applications on 64-bit OSs. Because the project applications go in the (shared) data area, and are listed explicitly in client_state.xml, you might get BOINC confused if such a project had to fetch new work when running in 64-bit mode - you might get apps which were incompatible with later 32-bit running.

To avoid that, you could lock the project down to 32-bit running with an app_info.xml - though that might defeat the purpose of running 64-bit in the first place.

well, I use only 3 projects now and almost constantly with app_info so it's not a problem - I more worried about will BOINC consider different OSes as different hosts and trash whole task cache and recreate host ID on each OS switch or not ?
