I'll try that with the hex editor. As for the swapping, I've
successfully swapped disks while installing DOS before, using the
method you described in your reply (I'm using the exact same floppies I
used before), but the host was Win2k while I'm using WinMe now. It
worked on W2k, but now it won't on Me. I'll check in the archives for an
answer (I think I had this trouble before so maybe I'll find my own
messages to help!).

If you want to verify yourself the validity of the disk, get an
hexadecimal editor and look at the images you have on your disk (the
floppies one). If they are valid boot disks, they should have 0x55 and
0xAA as the last two values of the first sector, that is offset 0x1FE
and 0x1FF respectively.
The BIOS uses those values to confirm if the image is valid or not.
As for the problem of switching disk, you would have to go in the
control menu and mark the floppy as removed, then mark it as inserted
again, this time with the new image in.
If you are using a disk image, I would believe that copying the disk2
image over the one setup in your bochsrc.txt, after ejecting it, would
make things works.
There was some posts in this same mailing list some time ago, maybe
digging in the archives could reveal a better answer to disk swapping.
(or maybe the new docs?)
