#139893 - Startup?
Responding to: ???'s previous message

If nothing ultraspecial is implemented PC waits scancodes from fixed set (i think scancodeset2).

That may be true in general operation but, at startup, the PC sends commands to the keyboard.

Also, in general, the PC may send commands to the keyboard at any time?

You could "test" this, and come up with some scheme that works on one specific PC with one specific set of applications - but, chances are you'd find that it'd fail on a different PC and/or different setup that requires a (slightly) different command sequence.

You could end up with a similar situation to those "cheap" PROM programmer implementations which assume that a Hex file must always have addresses in ascending order - they work more by luck than by design!
