OK i am surprised your installer hasn't told you this ?!!!
Also next time before posting a question, check that its not been asked B4, coz this has been asked quite a few times. Hit the search @ the top of the page, but this time i'll tell ya M8
OK for PS1/DVD movie, from standby mode press and HOLD reset until the Blue LED comes on thats it
Also to turn the chip OFF (note it will NOT boot Backups) Do the same as described above but hold the button for about 5 seconds, or until you can hear the disk speed greatly increase.
Please note Once in PS1/DVD mode it stays there so all you do is swap the next ps1 game in and press reset
Also note when switching between PS1 and PS2 modes give the console a few seconds i would say about 3, to give it enough time for power to stop running though the Chip, then power back up with preferred mode !! EASY
Peace out M8 !!!!
