Have written previously about my experiments with the very excellent Greaseweazle<\/a>; but that was reading things like my old Kings Quest 5.25″ floppy disks from my modern 12th Gen Intel PC running Windows 10.<\/p>\n\n\n\n

Recently I acquired some old pc hardware and put together a retro 486-DX pc. To that end, I needed to create a DOS boot disk for this old system. That meant I needed to write a 1.2mb DOS boot disk.<\/p>\n\n\n\n

Previously I used some boot disk images to create an old DOS virtual machine running Windows 1.0<\/a>. For that, I used a bunch of archived boot disks images from WinWorld<\/a> archive.<\/p>\n\n\n\n

But how do I write these little beasts?<\/p>\n\n\n\n

I floundered around with greaseweezle’s command line but this guide from Tech Tangents<\/a> really helped out. There’s clearly a lot more I need to learn, but this got me a bootable 5.25″ 1.2mb floppy disk. I was able to test it on 2 different drives, and both worked. So, that’s pretty sweet!<\/p>\n\n\n\n
