- You should be able to work around this using a device assignment in your
- config.sys file to assign a second letter to the 3.5" drive and give the
- second "phantom" floppy 720K parameters. Something like this:
-
- {DEVICE | DEVICEHIGH}=DRIVER.SYS /D:# /T:80 /S:9 /H:2 /C /F:2
-
- where # is the numeric designation of the 3.5" drive starting from 0:
- A=0, B=1.
-
- Now you use the new drive letter to format 720K.
-
- Let us know if this works.
