Next is reading the manaul page of mknod(1). Create a fake /dev/fd1, or even a real /dev/fd1 if virtualbox can provide a second floppy drive. Reboot in the vbox guest into Debian Installer. Get to a shell for commandline access. Use your new skills to create /dev/fd0 Then these commands mkdir floppy mount /dev/fd0 floppy And please report back > The natural question: Are those kernels different ? Yes. Think "several generations technology", example given i386, i486 and i586. All generations can boot with the oldest. Or thihk "All those drivers for audio, blue tooth, printers image scanners".
