could Dennix fit on a floppy? #8

Even today the floppies are still being used, for example - as virtual floppies inside the coreboot open source BIOS. Just imagine: your wonderful OS could be a part of someone's BIOS build! _(for coreboot supported motherboard, maybe you have or could get one - see https://www.coreboot.org/Supported_Motherboards )_

If you already have a coreboot-supported motherboard, or a real chance to get one, - wouldn't it be cool to be able to launch your own OS straight from the BIOS chip? ;) With one simple command its possible to add any floppy to coreboot BIOS build - and then you see it as a boot entry! Multiple floppies could be added this way (as long as you have enough space left inside the BIOS flash chip, luckily LZMA compression could be used for the stored floppies to reduce their occupied size)

The current size of a Dennix iso image is ~7.96MB, most Floppys are 1.44MB, so without some custom compression or a smaller file system format putting Dennix on a physical Floppy is impossible.

Theoretically putting Dennix on a "virtual" Floppy could be possible because the disk image can be any size you want. You just need coreboot to support variable sized disk images.
