Just some more status reports: The version of doscmd that I have is doscmd_fbsd-960923; I don't know if this is the latest version or not. Sean mentioned something about using ^T to display more information, I haven't been able to find anything to make it do that. With -current as of 2/4, and the last patch set I sent out, everything seems stable (although tracing with '-t' does not work, my fault). It seems that doscmd is lacking in some areas, at least wrt to OpenDOS. To wit, I have the following problems: - I can't boot OD off an emulated hard drive, but it will happily boot off of a real floppy or an emulated floppy (floppy image). - every now and then OD will hang while I'm typing - this may be due to the idle loop polling; I don't get this behavior under DOS 5. - if I pause for a long time, then hit a key, OD attempts to do an "OUTSB xa60", and then quits with an illegal instruction. :-( On the positive side, I've been able to run a lot of the OD utilities. I found 'dosbook' to be very nice, as well as the fact that most of the commands support a "/h"elp flag. This is useful for people like me who don't know the first thing about DOS. I've not been able to lock up or crash my system at all with doscmd; so there is likely something different between 2.2 and -current. If I get any time, I'll try getting 2.2 and playing with it. I'm definitely not a DOS hacker, so I really don't know what to look at. I just bought the van Gilluwe book (Undocumented PC) but it only seems to cover some BIOS calls - is there a better book to look at? -- Jonathan
