V9 / Points B-I

rfh1234 · 11-13-2003,03:39 PM

Hi I am having trouble getting PS2 backups to boot. I installed a Magic V on a brand new V9 unit. I have cleaned, resoldered, checked and rechecked bios pins for bridging. I am 99.999% certain that the bios is not my problem. I can see perfectly with a 10x mag glass. There is no bridging splattering, or balls

I was wondering what connections B through I do. It would be nice if someone knew exactly EACH wires function. They are on the back of the board and more difficult to solder and harder to check than the bios legs in my opinion. They may be the problem. Or they may have nothing to do with booting a ps2 backup and I can forget all about them

I saw a picture that gives an alternate location for these points on the front of the board on the chip that B & C go to on V7. They are twice as close together as the bios pins though. I was going to check continuity by holding one probe to the Magic chip on the correct pad and the other to the alternate location. Continuity would tell me that there was a successful connection. However many many many pins on these chips show continuity with various locations etc. so this idea won't work.

I don't know how else to reliably check these points B - I

The system plays movies, music, ps1 backups fine

It plays ps2 original games fine when chip is put to sleep

Regarding PSX backups. Do they only need the chip to have power/ground/scex/reset wires connected to work?

Do DVD-R movies or music discs use the chip in any way? If so, what connections are used

If I knew the answers to these I could eliminate certain wires, possibly many if them

Also, does anyone know if there is a problem with modchipca? I opened a ticket with them and have had no response, plus I ordered a couple chips on Monday and have not received them or an email yet. EVERY other time I've dealt with them I get an email with tracking # within an hour of placing an order and I ALWAYS have got my chips the next day. My open tickets are usually answered within a few hours also. Any news on them? Anybody?

Thanks much in advance

Try laying certain wires flat on the board like SCEX, R, D, E, and W.

your cd dvd points are to blame ie the points on the back

if i gather from this statement you mean that it does not boot ps2 orginals when the chip is "awake" then this problem is not unique - a few ppl have experienced this with magic v's on v9's

see http://www.ps2newz.net/forums/showth...hlight=magic+v

my theory is that the "r" wire needs to be twisted pair as do perhaps the clk wire - if it has one which i heven't checked, but i think it does as it doesn't seem to have an oscilator (not sure which wire would be the clck wire) - try using twisted pair on "r" and see if that works. I mention this beause some ppl experience probs with dms3 which on certain ps2 versions which by using twisted pair on those points fixed their problems - i think the "r" wire needs special attention as it is involved in timing

is it the 400c laser ?

rfh1234 · 11-14-2003,02:17 AM

I have no idea which laser it is

There is no longer a "W" wire

I certainly would still like to know what B-I wires do exactly.

The "R" wire was run apart from other wires. it does not cross any chips or other wires. It runs along the side of the board.

The link given was from another post of mine

Thanks

yeah i just realised now that link was from you lol (not enough coffee to keep me awake) - anyway try using twisted pair on the "r" wire and see if that works

I was just informed that the 50001 takes a special Magic V chip. It is stated on the Magic V product page but I didn't see it. I wish it was stated more clearly and in bigger letters or something. Hopefully others will read this and NOT make the same mistake

By the way, if anyone is interested in a Magic V chip for all PS2 except the 50001, let me know
