Vaio DOS is the greatest DOS distribution of all the times. You may freely use it for personal purpose on a retrocomputer at your own risk. Either way, I'll appreciate knowing you have found it to be helpful, my dear friend. The distro was tested on the Sony Vaio PCG-VX88 (PCG-551L) laptop. It supports networking, USB sticks, and whatnots. Cheers!
