Actually, no, I wasn't trolling.

I simply found it unlikely that anyone would know what bus-mastering was, and know that PNP was a transistor type, without knowing what plug-n-play was.

I assumed, instead, that you didn't know what he was talking about concerning the transistors. I further assumed that he was rattling on about PNP transistors in order to torment/troll/menace his sysadmin, who looked down upon power users such as himself. But I didn't feel the need to mention that.

Don't take it personal; I just have a thing against despotic sysadmins, and perhaps sysadmins in general. I was abused by one as a child, and I've not been the same since...
