Ah, ok, next message :) Well, you can use mine :)
1) Grab this: <http://suporte.cosmodata.com.br/downloads/moni/CosmoData-M15020.iso> 2) don't touch the COSMODAT dir... (no big deal, there is a password on sensitive files) 3) the FreeDOS/Disk is a perfect image of the boot disk, the CosmoDOS.img is the booting image. This iso works, you can burn it and test :) It is a version a few months older then FreeDOS 1.1. It is full GPL, all sources are included :) Alain Em 17-01-2012 21:07, Bob Cochran escreveu: > Alain, > > I would like to try your method.
