User's Guide
KeyMaker 8 USB LCD (KM8LCD)
functions are all selected by moving the Joystick tip Left, Right, Up and Down.
The main KM8LCD display
Joystick control
DOWN scrolls through all the
options available in the current menu level
Right selects the currently
displayed option and is also used to confirm you wish to perform the
currently displayed option.
LEFT and UP back out of
the current menu level
The Main Menu
Moving the Joystick tip Down
- engages the LCD Screen Menu and Joystick control
Pressing Down, again and again, scrolls
through all the Main Menu Options
The US displayed on the bottom right is to
remind you which ThinkPad Keyboard Language is currently set, US stands
for US English QWERTY, this is important when displaying recovered SVP
as the letters can change depending on the Keyboard.
Diagnostics is the last option on the
Main Menu, if you press Down once more, the Main Menu is repeated again
from the first option
As you scroll through the Main Menu
Options, if you wish to perform the currently displayed selection, you
move the joystick tip to the Right
For example, you have scrolled Down through
the main menu to LSI
You wish to perform an LSI operation - you
move the joystick tip to the Right
If you now move the joystick tip Down
once more, you will scroll through the next of the 2 options available in
the LSI menu
With SVP Clear displayed if you move the
Joystick tip to the Right you select that operation
If you confirm that you do indeed wish to
Clear SVP by moving the Joystick tip to the Right the Clear SVP
operation starts
Had you moved the Joystick tip in any
direction other than to the Right to confirm it, the operation is
aborted
When the SVP has been cleared you see this, which is to
remind you to go into BIOS Setup, select defaults F9 and save F10
All of the LCD - Joystick operations
also appear on your PC or Laptop screen if you are running your terminal
Software
Notice "Joystick active" is
displayed on the PC screen followed by the operations performed using the
LCD - Joystick
Also note the more complete message
following the operation
You can switch back and forth at any time
between the PC keyboard running your Terminal Software or using the LCD-
joystick
If the LCD- Joystick was last operated and
you wish to use the PC keyboard just press 0 [zero] and you have control,
photo below, 0 was pressed screen at Main Menu
If the last command was type on the PC keyboard
and you wish to switch over to the LCD - Joystick, simply move the
Joystick tip either Left or Up and you are back at the Main
display on the LCD with the Joystick in control
Trying to explain using the LCD - Joystick
in fact makes it appear to be much more difficult than it is to use it in
practice.
Down scrolls through all available
options at that Menu level.
Right selects/confirms that menu
level or operation.
Left gets you out of almost
anything.
KeyMaker 8 LCD EEPROM connections
Labelled above are connection point for LSI,
24RF08, 24C01 and 24C03 EEPROM types
NOTE: You ONLY ever use VCC
connection if you are reading or writing to an UNSOLDERED EEPROM,
in every other instance you do NOT connect VCC at all.
Labelled above are connection points for an
UNSOLDERED 93C46 EEPROM
The 93C46 can ONLY be read or written to
after it ahs been unsoldered from the system board, you should only
attempt to read a (3C46 if you in fact have the tools and know how to
unsolder a tiny surface mount chip without destroying it, do not even try
this if all you have is a big soldering iron.
The 93C46 EEPROM is very different, it
needs 6 connections and it MUST be unsoldered from the board in order to
recover the password stored in it.
ONLY unsolder a 93C46 if you have;
-
The right Surface Mount Device (SMD)
unsoldering/soldering tools
-
You have experience at using those
tools properly.
If in any doubt about about your ability to
unsolder a SMD 93C46 - I suggest you don't do it, rather have someone else
who does this for a living do it for you.
If you cheerfully go ahead and you don't
know what you are doing and lack the tools and skills required, you will
simply ruin the System Board and EEPROM
The following information is for those possessing
the right tools and skills.
You MUST solder a 0.1uF ceramic capacitor
between the 93C46 VCC and VSS pins.
NC means there is No Connection at all to
that pin.
Pin 6, ORG MUST be connected to VCC
All other pins connected to the same
labelled pins on KM9 LCD EEPROM connector
