DOS ENVIRONMENT AND COMMAND REFERENCE
DOS stands for Disk Operating System. Every time you turn on the CM9700-CC1 or every time you reboot (Alt +Ctrl +Del), the computer loads DOS
from the CC1 disk into the memory (RAM). Once loaded DOS lets you run other programs, in particular, the CM9700.EXE program.
from the CC1 disk into the memory (RAM). Once loaded DOS lets you run other programs, in particular, the CM9700.EXE program.
On factory-configured systems the autoexec.bat file is configured for one of the following scenarios:
•
The boot process ends at the following system prompt (c:\9700>).
•
The boot process loads and executes the CM9700.EXE program.
THE BOOT PROCESS
The following process occurs when the CC1 is turned on or is rebooted:
1. If turned OFF and then turned ON, the CC1 goes through a power-on self-test (POST). Here the computer essentially examines its electronic
components.
2. The computer looks at drive A for a DOS system disk. If one is not there, the CC1 will load DOS from its hard drive.
3. This process looks for two “hidden” system files: IO.SYS and MSDOS.SYS. If these files are not present, DOS displays the “Non-System
disk or disk error” message. (The CC1 also displays this error during the boot process if there is a floppy disk in the A drive that has no
system files).
