wine build question....

[GRIFFIN RANGER]

when i go into the kde controll panel... it tells me i have an i686 (its a
686/166MHz machine) 

so, my question is... should i be using the i386 build, or the i686 build???

as i have been using the i386 build, and I am having problems with acessing the
windows registry... i have also tried wine on a cel700, with the i386 build,
and i get the same problems... so should i be using the i686 build???? 

thanks for any help... im really keen to get wine working... even after it has
trashed by fat partitions :(
