4. If the “hidden” ﬁles are present, IO.SYS loads ﬁrst and executes. An initialization program called SYSINIT contained within IO.SYS reads in

the MSDOS.SYS ﬁle; SYSINIT next locates the CONFIG.SYS ﬁle and executes its ﬁles for it to conﬁgure itself in memory. Then, SYSINIT

locates and invokes COMMAND.COM. If SYSINIT cannot ﬁnd COMMAND.COM, DOS displays the “Bad or missing Command Interpreter“

error message.

5. If SYSINIT ﬁnds and loads COMMAND.COM, it, in turn, searches your root directory for the AUTOEXEC.BAT ﬁle. If it exits,

COMMAND.COM will cause the AUTOEXEC.BAT ﬁle to execute. If AUTOEXEC.BAT does not exist, the DATE and TIME commands are

invoked by COMMAND.COM. After entering date and time information, the basic system prompt (C:>) appears. This completes the startup

or boot process.

You cannot separate the boot process from CC1 initialization. The DOS boot process must succeed before the CM9700.EXE program can run. The

result of the DOS initialization process is that you either have a system prompt on a DOS screen or, as part of the boot process, the CM9700.EXE

program has been invoked. In the latter case, the System window of the diagnostic screen displays “Setup Complete…” if everything initialized

OK; otherwise, an applicable error message appears.

AUTOEXEC.BAT AND THE BOOT PROCESS

The AUTOEXEC.BAT ﬁle is the last ﬁle called during the boot process. For CC1s conﬁgured as part of a system node at the factory, the end result

of this process is the appearance of the CM9700 diagnostic screen on the attached VGA monitor.

The factory-conﬁgured boot process occurs because of the instructions added to the AUTOEXEC.BAT ﬁle. The AUTOEXEC.BAT ﬁle is a batch ﬁle,

which contains a series of instructions that are executed serially when the ﬁle is called.

Invoking the CM9700 Executable

The following commands are the last two in the AUTOEXEC.BAT ﬁle:

CD9700 This command directs DOS to the 9700 directory where the 9700 executable resides.

CM9700 Node1 This command starts the executable (CM9700) and directs the program to load into memory all conﬁguration ﬁles having the

collective preﬁx name of “Node1” (also located in the same directory).

The program continues to conﬁgure the system environment and goes on line. If everything is functioning properly, the “Setup Complete”

message appears on the CM9700 diagnostic System Window on the attached VGA monitor.

If you change the name (the preﬁx) of your current conﬁguration ﬁles or copy a new set of conﬁguration ﬁles (with a different name) to the 9700

directory, then you must change the AUTOEXEC.BAT ﬁle to correspond.

File Names and DOS

File names in DOS are limited to eight characters. If you issue a command to change the name of the conﬁguration ﬁles in the 9700 directory to a

name exceeding eight characters, the name is truncated to eight characters. The Windows-based CM9700-MGR program does not allow you to

use more than eight alphanumeric characters when creating a name for your set of conﬁguration ﬁles.

NOTE: Since COMMAND.COM is not a hidden ﬁle, it is possible that it could accidentally be moved, corrupted or erased. If this occurs, you

may need to start DOS from a ﬂoppy disk and COPY COMMAND.COM into the CC1s root directory.
