PDT 7200 Series Product Reference Guide
too few files may cause an application or environment to fail if it attempts to open too many
files. Unless there is a specific requirement for more files, we recommend using a value of
n=20.
• INSTALL = file.ext
Loads a TSR from CONFIG.SYS. It can be used to load TSRs (low only) that go along with
drivers (as a convenience). Note that DOS does not load the TSRs until the end of
CONFIG.SYS (as opposed to where they appear). If you use your application as a shell
(see SHELL=), you can use this command to load TSRs prior to execution of the application
as the shell.
• LASTDRIVE = x
Specifies the number of disk drives managed by DOS. This command is necessary only if
the number of drive letters managed by DOS must be increased. DOS automatically
allocates C: and possibly D:, E: and F:, if additional FLASH disk(s) are present.
CardSoft, the RAM disk driver, and DRVSPACE are device drivers that allocate new drive
letters beyond those automatically allocated by DOS. LASTDRIVE only adds new drive
letters (to be managed by DOS) if the drive letter specified is greater than the last drive
letter automatically allocated by DOS or by device drivers such as RAM Disk, CardSoft,
and/or DRVSPACE.
One common use of this command is to reserve one or more drive letters for use by the
DOS SUBST command, in addition to the drives needed for RAM Disk, CardSoft, and
DRVSPACE.
For example, if DOS is managing drives A-F, set LASTDRIVE=G.
For Spectrum24 use with Novell Netware and LAN Workplace TCP/IP stack, LASTDRIVE=
must be set to Z.
• NUMLOCK = [ON | OFF ]
Sets the state of the numeric lock key on the keyboard on boot up.
• SET
Sets environment variables in CONFIG.SYS instead of in AUTOEXEC.BAT.
Note: Environment variables are set in CONFIG.SYS only at the end of
CONFIG.SYS, regardless of where the SET command occurs.
Consequently, these settings cannot be used by device drivers, and
this command is generally only used if environment variables are
6-6
