When you use the HP tool - don't use a MSDOS 6.22 bootdisk for your base - try using this and see if this helps: Super MS-DOS 7.10 Boot Disk (Build: 2004.2.14) Updated! Note: The above Super MS-DOS 7.10 Boot Disk is a customized DOS boot disk that has many more features than standard DOS boot disks. Therefore, it also supports NTFS/USB drives, mouse, and many more. _http://newdos.yginfo.net/msdos71/ Please advise if it is any better.. Baxter
