MS-DOS Startup Menu
The default JANUS startup menu is defined in
the menu configuration block in the
CONFIG.SYS file. It defines several different
PC Card configurations that you can enable on
your JANUS device. You can modify or disable
the JANUS startup menu by removing or
changing parameters in the menu
configuration.
Refer to any MS-DOS 6.2 manual for more
information on setting up or changing the

Drive C contains the reader’s AUTOEXEC.BAT and CONFIG.SYS startup files,
as well as software for the PC card drive. You can use the remaining space on
drive C to store applications and data files. In general, drive C should contain
files that you often read or execute, but do not often write to or replace.
Drive C is a 512K ROM drive implemented in flash memory. It is upgradeable, but
has limited write capability. You can use DOS commands to read from drive C, but
you cannot use DOS commands to write to drive C.
To write to drive C, you must use one of these special utilities:
• Auto-Loader
• MakeDisk and PutDisk
• Binary file transfer (BFT)
These utilities let you create an image file that contains an “image” or
“snapshot” of all the files you want on drive C.
Then you use the utilities to load the image file to drive C.
Once you load the image file to drive C, the image file becomes transparent.
For example, when you use the DOS DIR command for a directory listing on
drive C, all you see are the individual files that were contained in the image
file. You cannot directly add, edit, or delete individual files on drive C. Instead,
you must replace the entire image.
