Voltage to the laser question...

A no solder mod connects in between the ribbon cable and the reset,eject buttons. It doesn't inject any type of boot code,The PS2 reads the boot code off the GS2,AR2 it then allows the tray to open without the CPU knowing it for backup swapHere's what ths pins on the chip actually do, in case you wanted to know:

PIN #1 = supplies + (power) to the chip
PIN #2 = sends SCE signal out to PS 2
PIN #3 = PS 2 drive tray pulse tells the BA5810FP chip whether to expect a drive tray open or close
PIN #4 = checks/signals RESET button on the PS 2
PIN #5 = closes PS 2 drive tray
PIN #6 = opens PS 2 drive tray
PIN #7 = checks if game CD is PSX/PS 2 (If PS 2, immediately stops SCE signal & restarts when a "tray close" is seen. If PSX, it stops after about 15-20 seconds)
PIN #8 = supplies ground to the chip
