Yeah, but... I'm not sure it is 100% correct, depending on the BIOS int 16/05 which might "STI" before returning, thereby allowing other processes to consume the injected key before we had a chance to check it reached the buffer. Possibly not a serious objection in practce, but needs more analysis and, frankly, the tests above should leave very few false positives while being perfectly safe.

Actually; ICBW but I think the only outliers must be very early revisions of the orignal, IBM brand, PC-AT. For those, identification of the BIOS by date and/or examination of the feature byte (int 15/C0, which is safe to call) and correlating with Ralf's interrupt list would be a good determination - and overkill too... such machines must rest in a tehnological museum.

Yeah but... it's Mouskeys we'd wish to have such a callable API !
