88AS8040 IDE2SATA Chip

[andrews2kx]

Hi.
A few months ago i developed one pcb called Dream IDe Reborn and i
registered here first to thanks to SWAT and your team, because if was not for Dreamshell, this job never was out of paper.

v1


actually v2 with some improvments:


Second because i want to share something.
Another day Me and Alexsandro (aldair) was talking about SATA adapters compatibility.

The simple green adapter has a small chip and i dont understand why this same adapter dont works if you just connect it with a ide cable, but works if you solder short wires.
Even in my pcb, without wires, this same adapter didnt works.

So, later i was looking a schematics of Startech´s adapter because it basically works if any console without problems. Works like a charm includes with my pcb:





So, i was looking for chip diagram to try to understand things and i found one scheme in a ps3devwiki site:

http://www.psdevwiki.com/ps3/88SA8040-TBC1

My job here is fix consoles and when i look that i jump from my chair and get a dead ps3 board in my shelf.

Take out original chip from an ide2sata bidirectional (this is NOT work in any console, because it haven´t master/slave selector - just "ide2sata" or "sata2ide") and soldered ps3 chip in place:










And it works like a charm!
PS3 chip code is 88A08040, Startech´s Adapter is 88AS8052. But both is same family, i checked pins before solder and runs ok.
Tested with 3,5" Western Digital 500gb Sata and 1,5", without any problem!

So i believe its a solution if you got a cheap ps3 dead board and already have ide mod installed.

Cheers!
Andrews

need v3, with this, this and this on board

you can use JMH330S , i'm can't find datasheet, i have shematic PC motherboard with JMH330 (is Serial ATA Bridge Chip in master mode (JMH330S in slave mode))

Thank you Megavolt! About building 1pcb - all in one:

I´m already buiding another pcb with a friend, but for bios. Still in development, because first prototypes have some issues that will we correct and test new pieces in next 15 days. Our idea is just clip, solder 2 or max 3 wires and play (but for now without prevision when will ready)



I will check your datasheets. Maybe i get draw something including sata directly.

DREAM_BIOS_REVOLUTION is bad way. BIOS on Dream IDE Reborn board is good. Need add two test point and remove R532 from main board

The idea is simply to facilitate the installation of DualBIOS. I can not believe the way it is done today can not be improved.



In fact, the board will only be fitted onto the MPR-XXXX harvest, which should have the pin 12 up and connected to the plate, a point with the WE signal is also necessary, simple, in a few minutes modbios / dual bios / region free installed!

I could not understand what it meant to be necessary to remove R532 on the main board?

In fact this board is nothing more than a dip44 adapter TSOP48 with a voltage regulator (for VA0 model plates with 5V voltage) and two resistors 10k fitted with a system that facilitates the connection of the MPR-XXXX, I did not understand why it would be bad idea to facilitate the mod as is done today.

I would also emphasize that the MX chip used is recommended by SWAT in UC's list compatible, could not understand where it would be based on the opnion that this card is a wrong way.

Could you tell us why you think that?

I want complete saying that here in Brazil, per example, many people refuses to leave gd rom because they still working. So if user want to play some game that Dreamshell still can´t run, they can use in normal way. Thats why i made Reborn for solder in the bottom of pcb.

I think megavolt85 mean some simples way with one PCB instead of two.
You can place MX chip on IDE Reborn, that has almost all pins for it, because the BIOS used the same bus (G1) as GD drive.
Solder the one PCB is easier than solder a two PCB. You make one work 2 times.

Many thanks for that. I will check bottom pins for bios and consider it in a next revision.

Now I understand, you mean that you need to remove R532 when using the chip mx on board IDE Dream Reborn?

The test made with integrated circuit MX29LV160 CBTC-70G, it was enough just to follow the pinout, and it was not necessary to remove any resistor ...

Цитата:Now I understand, you mean that you need to remove R532 when using the chip mx on board IDE Dream Reborn?

If you use my diagram, then R532 needs to be deleted, otherwise both BIOS can be activated at the same time

Thank you for your attention, I am an admirer of his work with Dreamshell

WARNING. don't use MX29LV160 on VA0 motherboard
on VA0 board all addres and data lines have 5V logic level
for VA0 use this diagram
added pin 14 (write protect), VCC from P166 (+5v)

I re-designed this project simply because it could be improved and no one had done it, and also wanted to prove the concept of running it all on one board.

I'm working on a new board that is already in the final stage of production that includes on the same board the modbios and an adapter ide / sata and do not need to cut the carcass, this is my goal, a preview can be seen here
