Driver.SyS Installing the
Driver.sys device
' ^ Driver.sys is an installable device driver that supports external driver
drives.
Note If you want to configure a logical device, use the
drivparm command described in Appendix B, "How to Configure
/—\ Your System."
To install driver.sys, you must use the following syntax for the
fmms)i command line in your config.sys file:
device = driver.sys /d:dd [/c] [li\ff\ [/hihh] [/n] [/s-ss] [/tttt]
The dd parameter on the /d: switch specifies a physical drive The Driver.sys
number between 0 and 255. Physical drives are numbered dif- switches
C*\ ferently than logical drives. Floppy drives are numbered starting
at 0, and hard drives are numbered starting at 80H.
For example, if you have a computer with two floppy drives, they
f^^S might be numbered 0 and 1. If you were to add an external
floppy drive, its physical drive number would be 02H.
^^^ If you have a computer with one floppy and one hard drive, the
(l floppy drive is numbered 00H, but the hard drive is numbered
80H. If you add an external floppy drive, its physical drive
number is still 02H because ms-dos already knows the definitions
f^) of physical drives 00H and 01H.
The /c switch specifies that change-line (doorlock) support is
required.
! ' The ff option on the /f: switch specifies the form factor index,
where:
/^ 0 = 320/360K bytes
1 = 1.2M bytes
2 = 720K bytes
^—v 3 = 8" single density
4 = 8" double density
5 = Hard disk
^^ 6 = Tape drive
f) 7 = Other
/-^ The default values for the following parameters depend upon the
form factor specified with the /f: switch. If you do not specify the
/f: switch, driver.sys uses a default of 720K bytes.
