That seems to have been a general IBM-ism.=C2=A0 The BIOSes= were the same way - they would display a series of numeric codes on the sc= reen and if it stopped somewhere you had to drag out the manual and look up= why.

I have a port 80 decoder that let's me see the same = thing but w/o the need for video to work... the same codes on the screen we= re outb'd to port 80... came in handy for driver debugging too
