It may have been > part of a VB There was a thing, DirectIO if I recall, that allowed Tait style PIC programmers to work on XP. However, Service Pack 2 made it almost, but not quite, impossible to install. If I recall it took like 6 r 8 reboots to actually install the thing, and if you tried to skip any it was remove and start all over. Once installed, however, it worked fine, and it seems to me that if you had it installed, installing SP2 didn't break it. Some time ago, however, most of the downloads for that package seem to have disappeared. I think that is one of the reasons W2K stayed so popular for so long. --McD -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
