I've heard that DOS can be told to start at some disk block which is not zero for its partition. I've seen that Venix-86 can't (yet). Tell Venix you have an ordinary XT, tell DOS that you want to start on some high-numbered block, either on the main drive (or on a different drive, if it lets you, but I don't remember seeing anything that said so). If all else fails, write a Venix command which reads DOS off the second disk and does a boot sequence for you. It should be much easier than doing it vice versa. Sorry that this is so general, but it's directionally accurate, I feel...
