The file that causes >this is called driver.com. You don't say whether you run driver.com or, as its name implies, it is a driver that you install to be loaded automagically at boot time. You also don't say whether you actually have a colour board etc. on your 6300. I must plead ignorance of the details of the 6300 per se; however I have been forced to work woth several 8086 machines, some "PC-compatible." One interesting thing is that the memory reserved for the video image -- different locations for B&W and colour -- can actually be at a non-IBM-standard location in some so-called compatibles. Causes no problems if you just use the DOS character-output calls; but if you access memory directly this causes problems. Especially if something else vital i s there. The program may also try to change something in DOS itself. This is an oft-necessary piece of hackery, considering exactly how useful DOS makes itself to people who are trying to do more than run Lotus and WordStar. However, if done in a quick-and-dirty manner or if the DOS on the 6300 is sufficiently different from PC-DOS, this can also write into unexpected areas. *** LONG LIVE UNIX.
