JANUS 2020 Hand-Held Computer User's Manual

User Flash Memory

User flash memory contains the 512K ROM drive C. It is mapped to 800000H.
The reader's drive C is similar to the hard drive C on your PC and contains the
startup files, CONFIG.SYS and AUTOEXEC.BAT.
Since drive C is a ROM drive that resides in flash memory, you cannot write
files to this drive as you would on your PC. You must use the Auto-Loader or
MkImage and PutImage to modify the startup files or change other files on
drive C. For help, see Chapter 3, "Learning About the Software."

Application Flash Memory

Application flash memory is the 2MB ROM drive D. It is mapped to C00000H.
DOS files and utilities are stored on drive D. You cannot modify or add files to
drive D. The reader uses approximately 80K of the application flash memory
for ROM DOS leaving a 1.943MB ROM drive D.
