Rufus can only extract DOS8 files from my WindowsXP. I also tried
HPUSBFW, which can specify DOS files location, so I used it to create
DOS7 and DOS8 USB boot disk (on the same USB-HDD, after Rufus
experiment, only io.sys and command.com), and the result is the same:
DOS8 can boot while DOS7 failed. Even simply copying DOS8 files to DOS7
formatted disk (I hope it excludes bootsector incompatibility) can make
it bootable. So I think DOS8 may be better with FAT32. The Disk is 8G.
