512K of RAM that gets divided between
System RAM and RAM Disk. If the RAM
disk has 254K then System RAM contains
258K. Similarly, a 1MB 95LX or lOOLX contains 1024K bytes of RAM. Initially that gets
divided, 398K for RAM Disk, 626K of System RAM. The 2MB lOOLX gets divided into
1,376K for RAM disk and 636K of System
RAM. The size of the RAM Disk can be increased or decreased.
You can change the System RAMIRAM
Disk ratio by closing all applications: On the
95LX press I <Shift > I-I FILERI System Memory.
Then use the left or right arrows to adjust the
ratio and press I ENTER I I ENTER I to set the
change. On the 100LX press I!], ~etup,
IMENU I, Qption, ~stem, tab to Memory and
use the right and left arrows to change the
memory allocation.
The greater the size of the RAM Disk, the
more space you have to permanently store
data files and program files. (If you run out
of space on the C drive, the internal RAM
Disk, you can install a memory card in the
PC card slot to store your files. This adds a
second RAM Disk which the system designates as the A drive.)
The greater the System RAM, the more
built-in applications (PHONE, MEMO, etc.)
you can run at the same time. Larger System
RAM also means that you can open bigger
files (i.e. larger 1-2-3 worksheets). Therefore,
if you want to switch back and forth between
large PHONE, APPT, 1-2-3, and MEMO
files, you might need to increase the size of
the System RAM. In addition to the built-in
applications the HP Palmtops can run other
MS-DOS or System Manager Compliant
programs that may require more System
RAM.
MS-DOS
An operating system serves as the intermediary between the computer's hardware and the
software it runs. The HP Palmtops, like any
IBM PC or PC-compatible computer, is a
"DOS machine." This means that the operating system is the Microsoft Disk Operating
System (referred to as "MS-DOS" or just
plain "DOS").
The fact the Palmtops are DOS machines
means that many DOS programs originally
designed for an IBM PC compatible computer
will either run directly on the Palmtop, or can
be modified to run (by the program's publisher) with relatively little effort. The 95LX's
40x16 screen, its small disk space, and its
lack of PC-compatible graphics support are
the major obstacles to software running on
the 95LX. The lOOLX will run more unmodified DOS programs because it supports CGA
Graphics and an 80x25 screen.
System Manager
The HP Palmtop has the advantage of being
both a DOS machine and of having a more
friendly and powerful second layer operating
system environment called "System Manager."

System Manager allows users to open
more than one program at once. This is not
normally possible in a straight MS-DOS
environment. Palmtop users don't think twice
about opening their PHONE book, then
switching to MEMO to jot down a note,
going to Lotus 1-2-3 to check some figures,
popping back to MEMO to finish the note,
and then returning to PHONE, exactly where
they left off.
In addition, you can add other System
Manager programs to the Palmtops. "System
Manager Compliant" programs are written to
be opened and run at the same time as the
built-in applications.
In general, System Manager and its FILER application do a good job of hiding many
of the complexities of the DOS environment
from the everyday user.
Directories
When you save a file, you save it into a
directory. The HP Palmtops come with the C
directory and the _DAT subdirectory built in.
PHONE, COMM, APPT, and HP CALC files
are automatically saved to the C:\_DAT directory on the both Palmtops. Lotus 1-2-3 files
are saved into the C:\ directory on the 95LX
and to the C:\_DAT directory on the 100LX.
The simplest way to get a practical understanding of this is to go into FILER. If the
top line says C:\ you can press I < DownArrow > I

to see the names of all the files in C:\. To
move to C:\_DAT directory, put the black
cursor line on _OAT and press IENTERI. To go
back to C:\, put the cursor on the line that
says .. View Up and press IENTERI.
In addition, the 95LX's C directory has a
_SYS subdirectory. If you open up FILER
you' ll see _DAT, but not _SYS. That's because _SYS is a "hidden" subdirectory on the
95LX that doesn't display in FILER as a
subdirectory of C:\, but it's still there and you
can go to it and view its contents. With the
cursor in the C:\ directory press ~ (Goto),
type in _SYS and press IENTERI. You should
get a listing of the files in the _SYS directory. These files are in permanent ROM. They
can be copied elsewhere, but cannot be erased
or modified and re-saved to the _SYS subdirectory on the 95LX.
The 100LX does not have a "hidden"
_SYS directory. Its system files are in permanent ROM on the D drive. You can view
these files in FILER by pressing ~ repeatedly until you see the listing of drive letters,
select [-D-] with the arrow keys and press
IENTER I. Again, these files can be copied elsewhere. But because they are in ROM, they
cannot be erased or modified and re-saved to
the D directory on the 100LX.
Spending the time needed to understand
these concepts will make your HP Palmtop
computing simpler and more effective.
