I guess I'm looking at this from the perspective of "it works under vanilla DOS", because it's fairly rare that something will be shipped that's _that_ bad, and going for the least sophisticated approach. Having said that of course there are plenty of things that don't have BIOS support at all, so you need some way of getting around that. *sigh* 8) For a disk BIOS, you'd then have (effectively) a bounce out of the penalty box to the read's real buffer, or whatever. Interrupt delivery may well be an issue; I'm not at all clear on that side of the issue. > Robert Nordier -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] "Who does BSD?"
