A few months ago when I was playing with a couple dvi's, I said that I *thought* I saw along the way, that if you use a 100 or 102 to copy the 100/200 version of the system disk, that the resulting copy can only boot 100 or 102, and can not boot a 200, even though the original can. IE, it's not a good copy, although if you only had a 100 or 102, you'd never know it, because it gives no error or warning along the way, and the resulting copy does boot a 100 or 102 just the same as the original. You'd never know the copies were bad.
I have now confirmed this, at least with my dvi, 102, & 200. If you have a DVI, and the 100/200 version of the system disk, try use only a 200 to make copies of that disk. If you only have a 100 or 102, and you obviously need to make copies for your own use since you want to minimize wear on the original, at least make sure they are labeled as no good for use with 200, even though the original is, and even though there are files for 200 on it, and it looks just like the original in all ways. -- bkw
