I don't think other DOSes route things through int25/int26 either, I tested that a few years ago. It would be a major headache anyway as int25/26 would reset the DOS stack pointer! RBIL explicitly mentions 480h 384 BYTEs disk stack (functions greater than 0Ch, INT 25,INT 26) in the SDA. To make a long story of Eric short, later versions hook at the device driver level, ie. what execrh.asm calls for FreeDOS. Searching a bit on google groups: interesting, this link talks about smartdrv but also about config.sys processing order: http://groups.google.com/groups?selm=1993Mar12.001843.20281%40microsoft.com Jen Kilmer posted more informative posts about smartdrv. If you even go further back you find posts from Mark Zbibowski (MZ) e.g. http://groups.google.com/groups?selm=8697%40microsoft.UUCP from 1984. Bart -- "Usenet is a strange place" -- Dennis M.
