Ah, Bret and I could surely provide you with source code for such an implementation. (Mine's in NASM syntax though.) Just saying, don't worry, I won't push it any more if you don't want it.

Understood.

Who/what is "Ciriaco"? http://www.funtener.org/ebooks-tutoriales-f6/el-un...el-ibm-pc-at-y-ps-2-ciriaco-garcia-t168184.html this one? I wasn't aware of this person. To address your point however, yeah, I confess I'm a fan of AMIS.

Just an idea, specifically seeing that the Int2F handler isn't necessary otherwise.

Assuming you mean a discussion where someone disagreed with me about AMIS, then it probably was with Jack. I don't remember it really though. And if you're referring to any specific technical point that we discussed then, you could as well point that out directly.

You could still add an interrupt handler walker to the uninstaller to take advantage of installed interrupt sharing protocol and AMIS-compatible handlers, even if your handler doesn't adhere to either. (Though I'd very much recommend at least implementing the Int15 handler with the interrupt sharing protocol.)
