	Just as a guess, since I haven't seen the 376 manual,
	but the 00110 bits should indicate an 80286-type interrupt
	gate while the 01110 bits are an 80386-type interrupt gate.
	This could be indicative of the software development
	environment used to create software for that processor.
	I don't know, but Intel may be showing a bias towards using
	the 80286 tool chain for producing executables for the 376.
	If this is not the case, then I would guess the 376 manual
	is hosed.

	As to the values in bits 5-7, those shouldn't matter
	according to the 80386/80486 scheme of doing things.
