Save and run programs
≡
Save and run your programs on the PC
Microcontroller
Once you have written, tested, and debugged your application, you can
then save it to flash memory in SSD0. When you reboot the PC
Microcontroller, your program can automatically load into DOS memory
and execute. As shipped from the factory, SSD0 already contains a
bootable ROM-DOS.
This chapter describes the following:
n
Saving an application program to SSD0
n
Autoexecuting the program from the PC Microcontroller
n
Overriding autoexecution of your program.
The information in this chapter assumes you will be using ROM-DOS in
your application. Some Microsoft programs make undocumented DOS
calls. With ROM-DOS, an error will be returned when an undocumented
DOS call is made, causing your program to operate erratically. We
recommend booting from SSD0 and using your own DOS, when using
programs with undocumented DOS calls. Refer to the Adding operating
system startup files section in this chapter for more information on
saving and autoexecuting programs.
This chapter also assumes you will be using the PC Microcontroller
without a video card/monitor. If you are using these devices, refer to
the Video chapter for more information on transferring and saving
programs.

Saving program and support files
By default, SSD0 comes from the factory preformatted, loaded with
Datalight’s ROM-DOS startup files and with an example demo pro-
gram. To replace the demo program on SSD0 with your own, see Add-
ing your application section in this chapter.
Formatting SSD0
This section describes how to format SSD0.
1. Define the SSD order with the SETSSD command. Since the command
input varies depending upon the parameters you would need to enter,
see the SETSSD command in the Software utilities chapter.
