1.2.2 Supported Software
The software used with this terminal can be divided into two categories: the system software that
includes the BIOS, OS, and device drivers and the user software such as the development tools.
The system software is stored on the DINOR FLASH ROM (1 MB), and the user software is
supported from the SDK CD-ROM (version 4.0) supplied by Casio at free of charge. The following
paragraphs describe the software.
BIOS
The BIOS program is stored in the DINOR FLASH ROM. 256 KB of DINOR FLASH ROM is
allocated specifically as the BIOS storage area.
The BIOS of this terminal consists of the standard PC/AT BIOS section, PEN BIOS for supporting
the touch panel, extension BIOS for supporting devices inherent to this terminal, and APM BIOS for
attain the low-power consumption capability.
MS-DOS Main Part
The main part of the MS-DOS Ver. 6.22 is stored in drive (C:).
In drive (C:) 768 KB of memory area in the DINOR FLASH ROM (1 MB) is allocated. Because of
the capacity limitation, only the essential MS-DOS files are stored in drive (C:). Therefore, if using
an MS-DOS file that is not included in the main part, copy it from the Backup CD-ROM (title on
CD-ROM: MS-DOS version 6.22 Software) to the F-ROM drive (D:) or RAM disk (A:).
For information about each MS-DOS file refer to an MS-DOS manual, commonly available at book
stores.

1.3 Precautions
 If reading the internal clock with INT21h the significant data should include and be limited to
the seconds digits. On this terminal the time is read directly from the RTC so that the correct
time can be attained at any moment, even during extended continuous use. As a result the 1/100
of a second digit is ignored. (refer to Chapter 7.3 “Clock Control Driver”.)
 To count time, the counter of DOS or the function provided for reading time must be used.
Time tick count of Windows will be behind 1 second in every 2 minutes.
 If it is necessary to reboot the system from an application, use the dedicated system library.
However, the reboot operation that uses INT19h of the BIOS I/F does not work.
 Many commercial PC programs use a VGA screen (80 (H) x 25 (V)). If these programs are run
on this terminal (24 (H) x 24 (V)) part of the message may not be displayed on the screen.
For example, some of messages displayed by Windows appear partly (left side of the messages
only) on the screen.
 Writing to a PC card should always be performed by terminating the write action through the
flash-out process. Otherwise, if system operation is suspended while writing to an SRAM card
or ATA card, the data on the card may be damaged. To activate this flash-out process use the
“_dos_commit()” function of Visual C/C++ or Commit Function (68h) of DOS.
 VGA controller is installed in IT-2000. Logically, it can display 16 different colors each in
single color though only 4 colors at a time are distinguishable. In case of development of
application program in single color, by having four colors, such as RGB (255,255,255), RGB
(192,192,192), RGB (128,128,128), RGB (0,0,0), will help you create an easy-to-see
application program.
Note:
If you wish to select a dither color, first display it on the screen to make sure. Due to technical
reasons the display of the B/W LCD may change to reverse video if an application program
developed by the user on a PC is executed without modification on this terminal. To restore the
normal display use the Reverse Video Utility (refer to Chapter 9.8 “Reverse Video Utility”).
 Key input operation is disabled for about one second after the Power has been turned off/on.
This is not a malfunction. This occurs because the monitoring timer starts operating the moment
the Power switch is turned on and does not allow any key input for about one second until this
timer expires. Thus, key input is not possible.

14
 If an LB1 event (low main battery voltage) occurs, the alarm buzzer starts sounding and system
operation is suspended about 10 minutes later. If the alarm buzzer starts sounding, terminate the
current operation as soon as possible and recharge the main battery.
 This system will not execute an alarm indication to be displayed on the LCD screen for an LB2
event (low sub-battery voltage) or LB3 event (low SRAM card battery voltage). Therefore, the
application program side must acquire these alarm status via the system library and display an
appropriate alarm message on the screen.
 If the volume of the buzzer is set to zero by the System Menu or system library, the LB1 (low
main battery voltage) alarm will not be heard. Also, other sounds issued by the system will be
inaudible.
 If the system is booted from a PC card and if a large-size program that resides on the card is
called from AUTOEXEC.BAT, an error may result. To avoid this problem refer to Chapter 4.2
“How to Write CONFIG.SYS and AUTOEXEC.BAT".
 The time limits that can be set for the Auto Power OFF (APO) function are 0 minute, 1 minute
and 30 seconds, 2 minutes and 30 seconds, up to a maximum of 15 minutes and 30 seconds.
This timer has an error of +/-23 seconds.
 Do not open the battery compartment lid while the power is on. If it is opened accidentally, an
emergency alarm sounds. In case such the event occurs, close the lid at once.
When you change the main battery, be sure to switch off the power before opening the lid.
 An SRAM card once formatted with the DT-9000 cannot be used or formatted with IT-2000.
 If the battery pack is installed for the first time after purchase, or if it is installed after the
IT-2000 unit has not been used for a long period of time, install the battery and wait for
approximately eight seconds before turning the power on. This must be done because it takes
approximately eight seconds until sufficient power can be raised for the emergency process.
And, during this interval the power cannot be turned on even if the Power switch is turned on.
 If the power is turned on for the first time after purchase and there is no installed application,
the System Menu will always appear. To start up the application, the application must be
installed first on the IT-2000. (refer to Chapter 8.4.4 “Installation of Application Program” )

15
 The backlight is turned off by means of the ABO (Auto Backlight OFF) function. However, it
is turned off 1.3 seconds after the setup time. This is because the system has 1.3 seconds of
monitoring time before the internal timer is started.
 During the process of loading Windows after boot-up, do not press the Power switch.
Do not press the Power switch because a processing request is issued before the process handler
is installed, resulting that the processing following the request can no longer be achieved.
 This terminal cannot avoid encountering the bugs inherent to Windows. If, for example, the File
Manager is used, dates (such as a date of file creation, etc.) on and after the year of 2000 will
not be displayed correctly. This is caused by a bug within Windows. However, note that the
internal clock will operate properly after the year 2000.
 The touch panel calibration program is not supported as part of Windows. Therefore, if
calibrating the touch panel with Windows, terminate Windows and execute the calibration
program from the DOS prompt screen, then return to Windows.
 The input process from the touch panel should be designed so that every designation can be
accepted with a single click. On this terminal a double-click can be ignored.
 For this system, the two display drivers of VGA_C.DRV and VGA_NC.DRV are provided.
The former will display the mouse cursor and the latter will not display the cursor nor the sand-
glass cursor.
 While a file in SRAM card is being opened under Windows, the operation of the access to the
card is aborted if suspend is executed. This will cause INT24 error when the access to the
SRAM card for writing or closing is continued after the resume. When you use an SRAM card
under Windows, please be sure to perform the operation steps in sequence of “open  write 
close”.
 Do not input “^P” from the DOS prompt. If it is input, “^P” requests DOS to redirect console
output to printer. However, because the IT-2000 does not have a built-in printer, it will enter
into wait mode.
For information about the system library, refer to Chapter 8.6.2, "System Library".
For information about the low voltage alarm notification function refer to Chapter 2.2.4 "Battery
Voltage Monitoring Process"

2.2 Basic System Operation
2.2.1 Overview
Basic operation of this system on the terminal consists of the suspend/resume process and boot
process operated by means of the Power switch and RESET switch, as shown in the following
diagram.
Fig. 2.3
During normal operation the system status will move between the ON state and the OFF state,
shown in the above diagram, by pressing the power key.
The SUSPEND state is a state from which the previous state can be returned to at any time. The
process of returning from the SUSPEND state to the ON state is called the resume process.
The RESET switch is used to either re-start the system or to initiate the System Menu, which is the
maintenance program. Press this RESET switch to start hardware initialization followed by initiation
of the System Menu. This process is called the System Menu boot process.
If an OFF event occurs while the System Menu is operating, the system shifts to the OFF state.
If the ON key is pressed in the OFF state, the boot process is executed again and an appropriate
application program will be loaded. This process is called the application boot process.

The following table summarizes the power-on processes provided for this terminal.
System Menu boot
process Always executes CONFIG.SYS and AUTOEXEC.BAT located in drive (C:) for starting up the MS-DOS.
Application boot process Searches for CONFIG.SYS and AUTOEXEC.BAT prepared
by the user and starts up MS-DOS from the drive where they are
located.
Resume process Restores the memory conditions that existed before the power
was turned off and continues operating according to the
conditions.
