Może to stary Messiah?

Had this trouble myself cos my dad collected mine and didn't ask. For the messiah chip for PS2 games you start the machine with the eject button. For PS1 games press the power button twice quickly after powering up i.e. at the boot up animation. Thats for messiah. I think its start up normally for DVDs. Don't use my PS2 for DVDs so not really sure.

Put your psx disk/dvd in tray and power off....then power on console holding in the standby button until the eject light turns blue then release and your dvds/psx games will boot (-;
