I believe you do. I created a boot floppy last night from the 6b3 CD. Have a formatted floppy and go the dosutils directory on the Cd and type rawrite. It will prompt you through the rest. Or, you can put the commands all on one line. I don't remember the format as I don't us that everyday.
There is also a way to do it at Linux server itself and the cd, but I don't use that command everyday as well.
