Appendix C Instal/able Device Drivers 2631
Driver.sys
Driver.sys is an installable device driver that supports external
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
command line in your config.sys file:
----------------------
device = driver.sys Id:dd [/c] [/fjll [!h:hh] [In] [/s:ss] [/t:ttt]
The dd parameter on the Id: switch specifies a physical drive
number between 0 and 255. Physical drives are numbered dif-
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
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
floppy drive is numbered OOH, 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
of physical drives OOH and OIH.
The Ic switch specifies that change-line (doorlock) support is
required.
The ff option on the If: switch specifies the form factor index,
where:
o = 320/360K bytes
1 1.2M bytes
2
720K bytes
3 8" single density
4 8"
double density
5 Hard disk
6
= Tape drive
7
= Other
The default values for the following parameters depend upon the
form factor specified with the If: switch. If you do not specify the
If: switch, driver.sys uses a default of 720K bytes.
