Oh Oh. v8 is supposed to be B 090 so hopefully existing Messiah 2s will work with the MX fabrication of the BIOS.

I think i installed a messiah 2 pro on a bios like that last week.
it worked flawless

OK this is a US console.

scph-39001
serial: au25*****
date code: 2d
GH- 022
bios-070

This is a costumer's PS2 i tried selling him a messiah2 but all he want is a magic 3.1 because he bought it for $ 15 USD.

Everytime i install the magic 3.1 it wount even load the originals games it gives a disk error. everytime i load either backups or orginals.
so i was think i might be a bad install. so took my v7 ps2 that is working with a magic 3.1 (red pcb) and i swap the boards. but its the same thing i still get the disc error.

So i decided to take the chip off the board of my customer" PS2 and tried loading a original game and iT works with no problems.

so i was thinking its probably the laser . are the v8 having the same problem.

the only diffrence between my board and the customers board its
next to GH and the bios chip look diffrend

my board
GH-022<-----------[3]

BIOS 070

customer's board
GH-022<-----------[2]

BIOS 070

It's just version 7.

I have seen around 5 pcb GH-022 already, is pretty common by now.

do any of your boards have a MX bios chip. i have two v7 one with a messiah 2 and one with a magic 3.1 and none of my v7's have this bios chip.

I saw a GH-019 with a "MX" bios and Magic3 worked fine on it, so Messiah2 should also work

Greets!

**woore** · 02-19-2003,12:25 PM

would it make a diffrence if GH-022 or GH-019

**woore** · 02-19-2003,12:31 PM

Just the memory chip near to chipset was reduced. Doing that will cut the costs to manufacture. And the other chipsets are more recent too.

In another GH-022 versions, the BIOS is more recent also, leading to so called v8.
