Booting Procedure question

[Milkshake]

I think my japan ps2 scph3000 is modded with an origachip v2.5 and I try to boot up a backup cdr game using the procedure outline From ORIGACHIP.COM web site (listed below).
I try the bootup procedure many time and when I select a DVD area the tray does not open automatically but instead my ps2 locks up. I have to use different procedure to `swap boot'. When the DVD area screen shows up I have to press the eject button (blue led) to manually open the tray and then swap for a CDR and then I have to press the eject button again to close the tray. Finally I have to press the start button to play the game.
Does this mean the modchip installed wrongly in my ps2 or there are other swap boot procedure that works.
Also when it say `choose a DVD area' press what button on the joy pad ?
