Before you can use any KeyMaker with attached KMX-LCD to unlock any TP you must first Activate the KeyMaker

If the Green EEPROM Activity LED on your KeyMaker is flashing continuously that means
it has not been Activated

NOT activated KMX1 flashing Green LED
 

There is a lot of text and a lot of photos on this page which may give the incorrect impression that using KMX1 or any KeyMaker together with KMX-LCD is really complicated, not so!

It is in fact very easy and convenient to use KMX1 together with KMX-LCD

Watch this short video first

Video - KMX1 together KMX-LCD recovering and Clearing Supervisor Password from a Lenovo R60

 

Then read all the text below.

Using KMX-LCD together with KMX1 series KeyMaker boards

KeyMaker KMX-LCD functions are all selected by moving the Joystick tip Left, Right, Up and Down.

The KMX-LCD initial display will vary depending on which KMX1 series board it is attached to

KMX1

KMX1 PRO

KMX1 PRO S


If you have not Activated your KMX1 it displays the KMX1 Serial Number, handy if you wish to email me your Serial Number and sort out the drivers and installing TeraTerm while you wait for your Product Activation key.

 

EEPROM connector on KMX-LCD follows the same convention as this early prototype.

When using KMX-LCD with KMX1 [the one with yellow headers]

The eeprom cable supplied with KMX1 with yellow headers is not 0.1" spacing so it will not fit the KMX-LCD I2C connector.

You have 2 choices for using the supplied eeprom cable

You can connect the separate leads to the KMX-LCD connector, split the supplied 4 pin black header and plug in 1 pin for GND and 2 pins for SDA and SCL

 

OR you can plug in the cable to the KMX1 board before plugging the KMX-LCD on top, there is sufficient clearance

All the EEPROM location pages show 2 connection points;

  1. SCL which you connect to the YELLOW lead above.
  2. SDA which you connect to the WHITE lead above.

  GND is the BLACK coloured lead.

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


From the Initial Display, moving the Joystick tip Down - engages LCD Control

Pressing Down, again and again, scrolls through all the Main Menu functions that can be

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 SVP letters you need to type vary depending on the Keyboard of that particular TP.

The "5 sec" is the currently set Delay, if ) delay has been selected then there is delay displayed.

Moving the Joystick tip Down - scrolls through all the available functions, starting with EEPROM selection
You can scroll back and forth through the Menu by moving the Joystick tip UP or DOWN

Moving the Joystick tip Down - scrolls through all the other functions

Note: only the KMX1 PRO S displays the Saved Passwords function


LCD Contrast adj is the last option on the Main Menu, if you press The Joystick tip Down once more, the Main Menu is repeated again from the start which is LSI

 

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 24RF08

 

You wish to perform an 24RF08 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 options available in the KMX1 24RF08 menu

The KMX1PRO and KMX1PROS display 2 additional functions, Repair CRC1 and Repair CRC2

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, if you have a delay other than zero seconds set, that delay will first count down, each second is displayed during the count down.

Delay count down at 2 seconds

 

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

 

If there are problems you may see one of these ERROR Messages displayed

Access Blocked - means that the TP has already booted to an Operating System, at that time the TP blocks access to parts of the EEPROM - solution is - switch the TP OFF and switch the TP ON again, NEXT TIME DO PAY MORE Attention about pressing the F1 Key at the right time so that you end up at BIOS setup or at a Password prompt or at an error message displayed on the TP and not booted into an OS

No response - error message can be caused by the probes not making good electrical contact with the EEPROM connection points, try again and pay more attention.

Fail SDA or SCL or BOTH LO - error messages can be caused by the probes being shorted to GND or the TP is not switched ON or the KMX1 I2C interface is damaged, if you suspect damage run the Diagnostic.

 

Adjusting LCD Contrast

Note: Contrast adjustment using the Joystick is only applicable to KMX1 or newer KeyMakers. By the way all existing KeyMakers can have their firmware upgraded to KMX1.

KMX-LCD used with KMX1 or later can have the LCD contrast adjusted using the Joystick.

Earlier KeyMakers KM7, KM9, KM9A use the potentiometer to adjust the LCD contrast. 

KMX-LCD board has an option jumper to switch between Joystick or potentiometer LCD contrast control.

The jumper should be removed for KMX1 and newer KeyMakers - this allows the KeyMaker board to control the LCD contrast.

 For earlier KeyMakers, leave the option jumper in place and use the potentiometer.

The following applies only to KMX1 or newer KeyMakers attached to KMX-LCD, see above.

To adjust LCD Contrast, you scroll down the menu by moving the joystick tip down, release, move down again until the LCD Contrast adj menu option is displayed

 

Moving the Joystick tip to the right selects the contrast adjust function

Move the Joystick tip up or down as many times as required to arrive at a contrast setting you prefer

going too far in either direction may make the display disappear completely or all the boxes go bright white

move the joystick in the opposite direction UP or DOWN until the contrast looks right for you

The contrast adjustment cycles to the end and starts again which means that you can keep going in the same direction UP or DOWN until you see the correct contrast.

Once you have the contrast at the point you like, move the Joystick tip to the left to exit the LCD Contrast ADJ function, the last set contrast setting is remembered even after you switch your KeyMaker off.

 

All of the LCD - Joystick operations also appear on your PC or Laptop screen if you are running your terminal Software

Notice "Joystick in control" [highlighted in blue] is displayed on the PC screen followed by the Clear LSI SVP operation performed using the LCD - Joystick.

If prompted for the Hard Disk Password and you don't know
the Hard disk Password, switch ThinkPad OFF, remove the Hard Disk
then try again to 'Enter BIOS Setup Utility'

In the BIOS Setup Utility, press F9 key to load SETUP DEFAULTS,
press ENTER key for YES, in STARTUP menu also use F9 and ENTER, then
press F10 key to SAVE and EXIT, Switch ThinkPad OFF and then back ON

ONLY THEN will the current operation be FULLY COMPLETED

VERY IMPORTANT - DO NOT IGNORE or SKIP any of the steps above

After completing Clear SVP operation, if on next switch ON
you see a BAD CRC error message, ignore the CRC error message
until you have followed ALL the instructions above


ONLY if you are all done,

Disconnect SDA first
Disconnect SCL next
Disconnect GND last

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 X [letter X] and you have control back on the PC

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.

Up or own scrolls through all available options at that Menu level.

Right selects/confirms that menu level or operation.

Left gets you out of almost anything.
