Of course, using dosemu + dexe to run "sys source: > target:" still works, but I'd like to do that using native linux tools. > Another way is to create a small bootable partition and use dd to read/write > image, but this way will work for this particular case only, cause some > specific info is still located in BPB/FAT table. :( I have a favourite way and a not-favourite way. The favourite way goes like this: Use linux fdisk to create the partition space but not the partition. Use a DOS boot disk to do the rest. The not-favourite way goes like this: do everything you've been doing, up to using mkdosfs to create the fs, then use dd to copy an MBR (and sector 0 boot sector?) to the partition. Should do the trick...
