Is there a solution? Am I doing something subtly wrong? This is why I paid the $20 to get my BIOS upgraded. In my config.sys I have: and it works great. The default for formatting is 1.44, and to do 720k I have to type "FORMAT /n:9 /t:80" and away it goes. The only hitch is in trying to save $$$ by using DSDD disks as HD ones; I had to install an "override" switch in series with the media detector hole in the Teac. (I'm told this isn't necessary with some other 3.5" drives, ie. Toshiba.) Also this was necessary to read a disk created on PS/2: they don't seem to care if a diskette has a hole or not.
