If I understand you correctly, the DOS program which is causing the problem is a program which has been written to run under DOS, and it is not MS-DOS itself which is spitting out fragmented characters. I am sure that DOS itself will work fine on PentiumIII and even better. Many programs have problems related to timing, some simply because of poor design and some because of known constraints which were accepted at the time the specifications were drawn up. I wonder which we are looking at here. Since you mention military applications you might be forgiven for letting us know very little about the programs, but I'm sure it would help if you could tell us exactly what is this problem program, where this fragmented output appears, what it looks like and under what circumstances it is fragmented. Precise details of the hardware configuration would also help. MS-DOS 6.22 itself works fine under the DOSEMU emulator, but there are all sorts of caveats about other software which you might want to run under a DOSEMU-controlled MS-DOS. Things like memory management and direct access to the I/O ports can be particularly knotty problems, and you can't run the processor in real mode at all - not that you'd probably want to. So what I'm saying is that although an emulator might solve many of your problems, it might introduce some too. If you can be a bit more forthcoming about your application's technical details, people here will be able to help you better. 73, Ged. - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
