This chapter explains how to make more memory available for applications, how to
access and use the boot loader screen, how to set the password, and how to put the
JANUS 2050 in Storage mode.
Making More RAM Available on the JANUS 2050
Your JANUS 2050 may not have enough conventional memory (RAM)
available for the JANUS applications you want to run. If so, you can free up
some conventional memory by not installing the PC card drivers and by
unloading two TSR programs (TSRs) from your JANUS 2050’s memory.
The next sections describe how and when to perform these tasks:
• Not installing the PC card drivers to free up about 60K.
• Unloading the Reader Wedge TSR to free up about 80K.
Note: If you do not need to free up more conventional memory on your JANUS 2050,
you do not have to perform these tasks.
Not Installing the PC Card Drivers
You do not need to install PC card drivers if you
are not using PC cards in your reader. You may
be able to save up to 60K in conventional
memory by not installing the drivers. Choose the
No PC Card option on the MS-DOS startup
menu and PC card drivers will not be installed
when you boot the reader.

Unloading the Reader Wedge TSR
The Reader Wedge TSR (RWTSR.EXE) must be loaded in memory before you
can call Reader Wedge PSK functions such as im_receive_input. However,
when you finish your PSK application, you no longer need RWTSR.EXE in
memory.
You can save about 80K by unloading RWTSR.EXE with this command:
rwtsr -d
You can load RWTSR.EXE with this command:
rwtsr
