GENERAL
The Toshiba T1200XE is one of the lightest portable computers
available offering high technology, high speed, excellent
legibility, IBM PC AT compatibility and battery machine.
The T1200XE's operating system is used with the MS-DOS versio~
4.0 and a powerful 80C286-12 microprocessor which has 16-bit
data width on the data bus line.
The memory capacity is 1 Mbyte as standard. The system can be
added one or two 2-Mbyte memory card, thus the system can be
added up to 5 Mbytes of R&~.
The internal 2.5-inch HDD (hard disk drive) has capacity of 20
Mbytes. The internal 3.5-inch FDD (floppy disk drive) supports
1.44-Mbyte 2HD (double-sided, high-density, double-track) and
720-Kbyte 2DD (double-sided, double density, double-track)
disks.
The keyboard is compatible with IBM enhanced keyboard which has
82 or 84 keys.
A sidelit LCD (liquid crystal display) comes with your T1200XE.
The screen supports 640 by 400 pixels with CGA (color graphics
adapter) compatible graphics and two cOlor attribute
combinations.
The power supply system is composed of AC adapter, batteries,
and one board which has two microprocessor.
The T1200XE provides connecting ports with the optional devices
at the rear panel of the system. There are one printer/
external FDD port, one RGB port, one serial port, and one
keypad port. Also, it provides the expansion connector for
Toshiba unique option devices, and built-in modern is installed
in the T1200XE as option.
The T1200XE's system unit is shown in figure 1-1 and its block
diagram is shown in figure 1-2.

Check
This indicator lights red if power is supplied from AC
adapter to the T1200XE when you connect the AC adapters to
T1200XE and a wall outlet. If the AC adapter's output
voltage is abnormal or the power supply board malfunctions,
the indicator labeled "DC IN" blinks red.
If the DC IN indicator blinks red or does not glow when
connecting the AC adapter to the computer, check the
following items.
Check 1
Unplug the AC adapter from the wall outlet and the
computer, then remove the battery pack.
Plug the AC adapter into the computer, then the
wall outlet and power on the computer.
If still its phenomenon remains, perform the check
2.

Check 1
Check that the following cables are connected to
power supply board correctly.
• Power supply connector

Perform the all HOD test. Detail operation is described in
part 3.
If the error is detected during the HOD test, an error code
and status will be displayed; perform the PROCEDURE 3. The
error code and status are described in table 2-3. If no
error is generated, HOD is normal.

TEST
RAM constant data (in real mode)
This subtest writes constant data to memory,
then reads and compares it with the original
data.
The constant data is FFFFH, AAAAH, 5555H, 0101H,
and OOOOH.
Subtest 02
RAM address pattern data (in real mode)
This subtest creates an address pattern by
XDRing (Exclusive-DRing) the address segment and
address offset, writes the address pattern into
the segment address and the offset address, then
reads and compares it with the original data.
Subtest 03
RAM refresh (in real mode)
This subtest writes 256 bytes of constant data
to memory, then reads and compares it with the
original data. The constant data is AAAAH and
5555H. There is a delay between the write and
the read operations.
Subtest 04
Protected mode
This subtest writes fixed data and address data
to memory (addresses 100000H to the maximum) in
protected mode, then reads and compares it with
the original data.
Subtest 05
Extended memory
For the memory located at the address 100000H or
more, the test program writes data, reads it
back, and compares in the microprocessor's
protected mode.
The data patterns used by the program are one
address pattern and four constant (i.e. fixed)
data patterns.
Address pattern data is a data generated by some
logical operation with its memory address

Backup memory
This subtest writes constant data (FFFFH, AAAAH,
5555H, OOOOH) to memory at addresses OE8000H to
OEFFFFH, then reads and compares it with the original
data.
Subtest 07
RAM on BIOS
A register controlling the RAM on BIOS function
is checked by a write/read/compare algorithm.
And, the functions specified by the register are
also verified. Then, the program compares the
copied BIOS code in the RAM with the original
code in the ROM.
Subtest 08
H-RAM
Registers controlling the Hard-RAM function is
checked by a write/read/compare algorithm. And,
the functions specified by the registers are
also verified. Then, the program compares the
copied BIOS code in the RAM with the original
code in the ROM.
Finally, the memory assigned as Hard-RAM is
checked by a write/read/compare algorithm using
a Hard-RAM window.
Subtest 09
LIM/EMS mode (in real mode)
Registers controlling the LIM-EMS are checked.
Page information is written at the beginning of
each page to verify its paging function. Then,
the memory assigned as LIM-EMS is checked by a
write/read/compare algorithm using a LIM-EMS
window.

In subtest 01 to subtest 05, data transmission is done with
the following format:
Speed:

Data:
8 bits and one parity bit (EVEN)
One stop bit
Data pattern:
Subtest 01
20H to 7EH
Wraparound (channel *1)
NOTE: The RS-232-C wraparound connector must
be connected to channel #1 to execute this test.
The wiring diagram of the RS-232-C wraparound
connector is described in section 3.23.
A data send/receive test is performed with the
wraparound connector for the channel *1.
Subtest 02
Wraparound (channel *2)
The same test as the subtest 01 is performed for
the channel #2.
Subtest 03
Point to point (send)
NOTE: This subtest must be executed in condition that two machines are connected with the
RS-232-C direct cable and one side should be set
as 'send' and the other set as 'receive'. The
wiring diagram of the RS-232-C direct cable is
described in section 3.23. The subtest 03
executed in one side and the subtest 04 executed
in the other will check the communication
capability as follows:
A block of data (20H to 7EH) is sent from one
side to the other, and then returned back. The
returned data is compared with the original one.
This test is used to check. ,,,hether the returnee.

Subtest 04
Point to point (receive)
This subtest is used with the subtest 03 as
described above.
Subtest 05
Card modem loopback
If there is no modem card in the system,
this test cannot be executed.
NOTE:
This subtest is used to check whether the data
to be sent from the modem card to the RS-232-C
line is correct or not. This can be done with
the loopback function inside the modem card.
Subtest 06
Card modem on-line test
This test requires two machines which
are connected to the PBX (Private Branch
Exchange). One side is set as 'send' and the
other set as 'receive'. When both sides are
ready, you can start the test.
NOTE:
In this subtest, data are sent from the 'send'
side to the 'receive' side through the PBX.
This subtest is used to check whether data
transmission through a telephone line is done
properly or not.
Subtest 07
Dial tester test
NOTE:
To execute this subtest, a dial tester
must be connected to the s stem.
This subtest is carried out by sending the pulse
dial and tone dial twice automatically.

Physical formatting
Logical formatting
This program is for physical formatting of the hard disk; it
can execute the following items:
1.

3.
4.
All track FORMAT
Good track FORMAT
Bad track FORMAT
Bad track CHECK
The contents of the hard disk will be
erased when this program is run. Before running the
program, transfer the contents of the hard disk onto
a floppy disk. This can be done with the MS-DOS
BACKUP command.
(See the MS-DOS manual for
