I'll have to do a bit more research on this then

Well the hard disk I'll be installing on will have plenty of space so I could set up 2 or 3 2GB partitions with a copy of DOS/FreeDOS in each. But again I'll need to try and clarify the FAT32 booting issue.

Just had another look at that article - "Bootup from a Win98SE boot floppy or 98SE MS-DOS boot CD/Flash drive. Type A:\SYS C: at the Prompt and press Enter
- this creates a DOS boot sector on the FAT32 partition and installs a very basic MS-DOS 7.10"

so you are correct about the need for some programs on the first partition, although the remainder can be in its own partition.

That's good.

Yes, fun, fun, fun!

Yes, I've come round to that way of thinking.
