SUMMARY
Pacific Rim Systems has confirmed that MS-DOS 5.0 and later versions may incorrectly attempt to format a 3.5-inch disk as a 5.25-inch disk on their external floppy disk drives for the IBM PS/2 series of computers.

A possible solution to this problem is to use the MS-DOS DRIVPARM command and the DRIVER.SYS utility.



MORE INFORMATION
To set the disk drive characteristics with the DRIVPARM command, add the following line to the CONFIG.SYS file:   drivparm= /d:x /f:y (where  is the physical drive number and   is the drive type).

See page 455 of the version 5.0 &quot;Microsoft MS-DOS User's Guide and Reference&quot; for correct drive type information for your floppy disk drive. Information for version 6.0 and later versions is in online Help.

If the DRIVPARM command does not solve the problem, install DRIVER.SYS in the CONFIG.SYS file, as follows:   device= \driver.sys /d:1 /n /f:1 where  is the location of the DRIVER.SYS file.

See page 602 of the version 5.0 &quot;Microsoft MS-DOS User's Guide and Reference&quot; for more information about DRIVER.SYS. Information for version 6.0 and later versions is in online Help.
