DRIVPARM--Notes

Using the /I switch

Use the /I switch if your system does not support 3.5-inch floppy disk
drives. (Some IBM PC/AT-compatible systems do not have a ROM BIOS that
supports 3.5-inch floppy disk drives.)

Disk drive change-line support

Change-line support means that a physical disk drive can detect whether the
drive door is opened and closed. Change-line support improves performance by
letting MS-DOS know when one floppy disk has been replaced by another. The
/C switch allows MS-DOS to make use of change-line support. To find out
whether your disk drive has change-line support, see your disk-drive
documentation.

Creating a logical drive

DRIVPARM modifies the parameters of an existing physical drive and does not
create a new logical drive.
