Is this the boot procedure you are looking for?
Magic 3, 3.1
NOTE: This is with the disk assumed in the tray and the tray closed:
Playstation 2 Games
• Power up normally from STANDBY with RESET button. A single tap is required.
Playstation 1 games & DVD Movies
• Power up from STANDBY with RESET button held until the blue EJECT light comes on; then release RESET and the disk will boot.
NOTE: Turn off the PS2 (to standby) before changing Mode (PS1/PS2/DVD)
NOTE: To turn off the modchip....... Hold reset for 3-5 seconds.
Some PS2 games are on dvd and some on cd. It will say on the back of the box which are which. Use RecordNowMax to back up your PS2 games
Hope that helps
