Method 4 - A Bootdisk.Com Visitor Suggested

Here is my another method for creating dos bootable USB sticks using windows format.
1. From Win98 DOS-Prompt type "SYS {USBDriveLetter}:" or "FORMAT {USBDriveLetter} /U /S". If from WinXp then from start->run command.com execute format.exe copied from win95 or win98.
OR
2. Simply by enabling copy system files in windows explorer format window. By default it is disabled for non-floppy drives. To enable it use windows enabler program from http://www.angelfire.com/falcon/speedload/Enabler.htm an whoila it works.
