You're corroborating my findings, both experimental and wikipedian. PC-DOS shouldn't need the hack.

Yes I suppose it was kind of a necessary passing rite for likely minded people. I then found it a necessity to hack the DOS from beneath itself, which was facilitated once I noticed that my industrial AT look alike (one of the rare clones made with IBM's *approval* in the mid 80's) featured a mini debugger built in to the BIOS (instead of the useless "ROM Basic" or press a key to reboot...) that for instance allowed to interrupt the system any time without paying respect to the so-called "IN-DOS" flag.

But that was soon not enough to satisfy my debugging appetites, especially when I started building a 80286-protected mode monitor. My next hack was a NMI switch, efficient although a primitive design, made out of a trombone-shaped desktop clip inserted into the rear of an available ISA slot - of course my machines ran top-less ;=) Real men don't need no damping resistors nor debouncing circuits (don't do that with nowadays' motherboards!)
