Personally I think that either this guy did something incorrectly or there's a Windows 3.1 bug. Meanwhile, Rafael's Linux-based OS is going to boot from this floppy like it's a ramdisk, so hopefully should be indifferent to the custom floppy sizes and would work. I share the same hopes for KolibriOS: although its' 1.44MB floppy contains really a LOT of stuff, some cool things like console emulators didn't fit - so I'm going to create the extended Kolibri floppy version, which will be either 2.88MB or some custom ( 1.44MB * X ) size.
