i have never seen this bios chip before

hey u guys is this a v7

gh-022 <----------
bios 070

well this wat is saying on the bios chip


MX s024033
mx23l4800yc-10g
(C)2002 scei
d 110 050 m48
b 10 070
2g387000

is this a v7 or v7.1

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!

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

hey gradius did u ever installed a magic 3.1 on one of these MX units

And GUICHI is chris having problems with MX units too. i know he only works with magic chips

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.
