Hah, gotcha! You tought this was a "where do I download blahblah." :)
but, the question is, HOW do I get the bios rom from the PSX (the grey box, you know :) to computer? It's kinda new machine and it doesn't have the paraller port at the back, so no gamesharks or the like.
(the code at the bottom is SCPH-9002) and it's the grey thingy, not PSOne.

From adripsx faq.

To dump a PlayStation BIOS, you need a GameShark or Action replay and a PC comms link. To start, you need either a real Caetla module or go to altavista and search for "Caetla" (it's a BIOS replacement for your module, so properly read the included documentation before installing it!!). Now upload "Caetla", and use use the caetla commands for downloading a binary memory image from the region 0x0bfc00000 - 0x0bfc7ffff! Now save the image as SCPHxxxx.bin, where xxxx is your PSX's model number, and AdriPSX will recognise it and use it from now on.

I hope it helps.;)
that wont work because he has a 900x model. those do not have a serial port installed. so unfortunately, you must install one manually by getting the part online somewhere.
