Heh... you must have just gotten up in England, while I'm well past the time when most people get to sleep around here Neil.

Anyway... I couldn't resist but play. Turns out the FDD doesn't care one iota how the file are put onto it to make it bootable. I copied files from a boot FDD to my HDD, formatted the FDD to make darned sure I was starting fresh (not that it would really have mattered), and then copied a bunch of command files back to it first, like format.com and fdisk.exe >before< the four system files. Even then, I mixed up the order of copying io.sys, msdos.sys, drvspace.bin and command.com. No matter how I mixed up the copy order, the system (my L70 sitting beside the L100 now) booted just fine.

So it would seem that copying the files back and forth seems to be as reliable a process as copying a disk image.

Correct. The imaging software preserves the exact bit-pattern on the disk.
Which means that you can make disks with various formats and flavours, and
they don't even have to be readable with the system you have running.

Though this is not guaranteed to work if you want to do things like stuffing
1.8M onto a 1.4M disk, per some microsoft installation floppies.
