Got my key chip 28 for my gk 6.2 on 044 board. Need procedures

[vpguy]

I want to look around the menus and possibly make a few adjustments. Can someone provide the key chipping procedure for this particular machine. Are there any perils of doing this?  Can I get the machine locked up if I do something wrong?  I am familiar with static precautions.
I don't plan on changing anything that I don't fully understand (bill accepter, printer, communication protocols etc). I also want to be ready when my Tito board arrives as this requires key chip changes.

Thanks

I found what appears to be the key chip procedures in the downloads section.  It's a little different than other key chip procedures, it's menu driven once you put the key chip in.  It seems to be that way because this single chip does multiple things, key chip, and memory clear operations.

How to use the KEY00028 program:

1. Replace boot PROM with KEY00028 and power up machine.

2. Initial menu for selections are shown for RAM OPERATIONS, EEPROM OPERATIONS, and KEYCHIP (see Figure A). Note: This keychip uses the touchscreen in place of the attendant key and test switch.

3. The user can expand or collapse the selections that have a "+" on the left side of the menu item (see Figure B) by touching the menu item.

4. If "CLEAR ALL RAM" is selected, the user is prompted with a yes/no window to confirm the selection (see Figure C).

5. If "CLEAR MOTHERBOARD E2" is selected, the user is prompted with a yes/no window to confirm the selection (see Figure D).

6. If “KEYCHIP� is selected, the user is prompted with a yes/no window to confirm the selection (see Figure E).

Note: It is important to understand that the options in KEY00028 are processed when they are confirmed. Keychips with the “REBOOT MACHINE� option will apply the selected items in the correct order. If KEY00028 is used, clearing of RAM and E2 should be done before setting the keychip flag.

[[ edit ]]  I tried the key chip tonight and it worked like a champ.  Have to keep the door open or else it just resets back to the game.
