Switching the Default to DOS Control
Normally, the System Manager is the default control program. Before you even
consider changing the default control program to the DOS-based COMMAND
program, be sure you understand the function of the special DOS file CONF IG . SYS
and exactly how it works in your Palmtop (see pages 124-125). There are two good
reasons to “boot up” to DOS instead of the System Manager:
* You primarily use your Palmtop to run DOS-based programs that you've
loaded into RAM on one of the two available disks (the internal C# disk or the
optional, external A% card-based disk). You probably prefer to use DOS-based
programs that you're already familiar with to manage appointments, phone
books, databases, etc., instead of using the built-in applications of the HP 95LX
(or you don’t use these information management applications very often).
* You want to do some customized boot-up initializing (using CONF IG .SYS
and/or AUTOEXEC . BAT files) before switching to the System Manager and
working primarily under its control for the duration of the session.
Keep in mind that changing the default means that your HP 95LX will “boot up”
to the DOS prompt—none of the application keys will be active until you switch
to the System Manager (see below). To change the default:
1. Gain access tothe DOS prompt by quitting all applications except the Filer and
pressing (MENU), (Slystem.
2. Create a CONFIG .SYS file (if one doesn’t already exist), and add the
following line to it: SHELL=COMMAND -P.
3. Reboot the machine by pressing (CTRL), (ALT), and (DEL}—all simultaneously.
Switching Temporarily to ¥SYSMGR (System Manager) Control
If the DOS COMMAMD is your default control program (see previous section), you
can switch to the System Manager by typing $#SYSMGR and pressing (ENTER). But
you cannot return back to DOS simply by “exiting” the System Manager (there is
no way to “exit” the System Manager—even when the default control program is
DOS). To return to DOS, you must invoke it through the Filer’s (Slystem command
(after quitting all other open applications)—just as if you were switching only
temporarily to DOS control (see page 114).
