This boot method uses SYSLINUX/MEMDISK to boot an emulated floppy image to simply install FreeDOS to the hard disk. > Then, I rebooted the LiveCD and out of curiosity I picked the last menu item > "FreeDOS is a trademark...": to my surprise, the system did boot, asking me > if I wanted to install to HD.

This was shown in the FreeDOS 1.3-RC4 Easter Egg video. https://youtu.be/SB17eypovvY <https://youtu.be/SB17eypovvY> It uses a similar process. However, it boots a small emulated hard disk image. This leaves the Floppies alone. It also requires no DOS level CD/DVD support. > Then I booted once again, this time picking the first menu item "Use FreeDOS > 1.3 in live Environment mode", and the system loaded a LOT of packages it > didn't bother to earlier, ending with R: as the main/current drive letter > (volume "FD13-RAMDRV"), and with A: assigned to a new volume "FD13-HYDRA”. This method boots a different Floppy Image and starts the process to bring the LiveCD Environment up. And when possible, initializes a RAM drive as drive R: and also if possible, transfers control and the DOS over to that drive and runs the OS from there. > So, it seems that FreeDOS has (at least) three different behaviors about how > to assign drive letters, one of which is fortunately suiting my needs. Albeit > a bit confusing for my newbie skills, at least I can work from there now :) The USB images boot using the BIOS to support them directly as a Hard Drive. Also, The Legacy CD does not use MEMDISK/SYSLINUX in favor of BIOS El Torito Support. So, basically there are 5 boot schemes. This of course does not count the CD Boot Floppy or the Floppy Edition Release. But, those are just boot directly from real floppy disk drives. :-) Jerome
