They also used a native mode driver for the demo... that >driver is supposed to be avaliable within the next 6 weeks. I was told that the demo used "as of yet undocumented features of GS/OS." Specifically, (according to the person that I talked to) there's supposed to be a "higher-level" read call (so that more gunk can be handled within GS/OS), which includes something vaguely resembling a loop (sorry, my memory is far from perfect). As for the drivers: I thought that the current (as of System 5.0.x) SCSI drivers (both supervisory and device specific) _are_ native mode. If they weren't, why would there be drivers for them sitting on my HD? (if they weren't native drivers, they'd just be generated drivers that went through the Smart- Port, right?) Perhaps the drivers were improved somehow? What's the deal with the other SCSI drivers (scanner and something else, which I forget at the moment)? I recall reading somewhere (IIgs buyers guide?) that they were being given to developers, but weren't yet ready for the general public. Were they distributed with the DMA SCSI card? -- Jason Blochowiak - jason@madnix.UUCP or, try: astroatc!nicmad!madnix!jason@spool.cs.wisc.edu "Education, like neurosis, begins at home." - Milton R.
