Recently, something very BAD happened:

I hacked on the USEDPMI.ASM example (generously discussed in other forum ) - and got a true flat ZERO-based memory model !!! With very marginal adjustments only What's wrong ? Is the statement correct ? Did I miss something ? Where is the limitation supposed to come from ?
