mbbrutmanComing soon ... a utility to make swapping active partitions easier.On my PCjr I like to switch between DOS 3.3 and DOS 5, while keeping the drive letters in the extended partition the same. To do that you have to mark the new partition active, but also hide the old partition. FDISK doesn't allow that.Other tools exist but they are often not small machine friendly. I wrote a similar utility years ago but I lost the source code, so here it is recreated and enhanced.<a href="https://mastodon.sdf.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://mastodon.sdf.org/tags/dos" class="mention hashtag" rel="nofollow noopener" target="_blank">#dos</a>
