Question: How to creating a B&R Power Panel DOS boot diskette in 4PP420.0571-75 Windows XP?

Answer: • Place an empty 1.44 MB HD diskette in the disk drive. • Open Windows Explorer. • Right-click on the 3?" floppy icon and select "Format...". • Then select the checkbox "Create an MS-DOS startup disk", press "Start" and acknowledge the warning message with "OK".After creating the startup disk, some of the files must be deleted because of the size of the update. When doing this, all files (hidden, system files, etc.) must be shown on the diskette. In Explorer, go to the Tools menu, select Folder Options... and open the View tab. Now deactivate the option Hide protected operating system files (Recommended) (activated by default) and activate the option Show hidden files and folders. Now all files (marked) except Command.com, IO.sys and MSDOS.sys can be deleted.
