  But you can have a perfect match... set the drive type to one and fill
in the blanks.

You can customize the geometry, it's an entry on the menu you get when
you run cc00:5.

|I ran SI on C:, and the index is 3.6, compared with 2.7 in MFM 3:1 case.

Did you set 1:1 interleave? You should get about 798 Kb/s.

What I want to know is, what is this junk (and all the 'helpful' replies)
doing in comp.sys.ibm.pc.programmer?

How about somethig like this:

OLD21_ADDR	DD	?	; YOU HAVE TO GET THIS ADDRESS

INT21_HANDLER	PROC	FAR
	PUSHF
	CMP	AH,6
	JZ	SPECIAL
	CMP	AH,0BH
	JZ	SPECIAL
	
GOTO_OLD_INT21:
	POPF
	JMP	DWORD PTR CS:OLD21_ADDR

SPECIAL:
	POPF
	; INSERT YOUR JUNK HERE
	IRET
INT21_HANDLER	ENDP


...JUST A THOUGHT...
