There are no significant differences between the two USB images. Off the top of my head, these are the differences that “should be” irrelevant. 1) Size of the two images. 2) Volume labels. 3) small usb contains the “Base” package list and base packages. The big usb has “Base” and “Full” package lists and base+full packages. 4) The big usb also contains a copy of the Floppy Edition in a sub-directory. > > Alas neither fdisk /info nor /status nor /dump in FreeDOS will > show details about reported LBA and CHS geometry, drive numbers > and similar BIOS information, but I would habe been interested > in exactly such things when it comes to thinking about why one > USB boot image behaves different from another. > > Maybe you can use different tools for those comparisons? > > Thanks!
