PS2 How to boot into MOD chip Settings ????(Modchip- Super7 E17)

[L2000]

Where does Matrix infinity 1.93 saves the settings??

I mean the settings you can change from the menu you access by pressing + at boot.

If I press start for saving, it freezes. I thought the chip itself had some memory to where store the changes. Do I need some path on the memory card? Perhaps it is freezing 'cause it doesn't find the folder where to save.

I couldn't find a single discussion anywhere online about this simple thing, not even in the matrix infinity official pdf manual.

The settings are saved directly to the spi flash chip onboard of the modchip , some chinese clones don't save settings and they definitely cannot be updated , the spi flash chip either corrupts itself and prevents further writes or it writes ffff's to certain sectors . This causes the chip to stop working .This can recovered by removing the corrupted spi chip and replacing with a regular bios chip that is known to be rewritable of the same or similar type , I've recovered a Modbo 4.0 using a 256 kb bios chip and a dump from a working Modbo 4.0 fw 1.99 ( I am looking for someone who can send me a dump of the 1.93 fw for Modbo 4.0 ) , you will need an external flasher to recover a chip but if you can do this replacement your Modbo will be able to save it's settings .You will not be able to update the chip as to yet using the Matrix Infinity Manager as the unmodified Matrix fw has some differences in code and writing that to the new chip causes it to black screen and not boot , I dont know if its for the PSX boot logo as most Modbo's don't display the PSX boot logo and Modbo has an external clock .

On some memory on modchip itself.

Thank you for the explanation.

The fact is that I'm just setting up an internal HDD for a relative. He bought a fat Ps2 (the cheapest possible one) appositely for it and surprise surprise it is chipped (the seller didn't mentioned about it...).

So I had to step back in the plan of setting the HDD with FHDB 1.966. I installed FMCB 1.953 on a MC as best workaround.

Since the modchip have some screen corrections (and also other crap enabled by default) the OSDSYS is a bit cutted at top screen. Anyway OPL seems fine.

I have to give him the Ps2 these days (it's a months or more since I started to set the HDD, I can't easilly find any good free time).

When I press start for saving settings it freezes there, no BSOD, simply the screen remains as it is (you can see a frame like it tries to transit to another screen but fails). So, just for curiosity, what in practice I'd need for flashing it?

I don't think I'll do anything risky though. I have zero experience with modchips and the Ps2 isn't mine.

Usually Matrix Infinity and Modbo can be disabled by holding START at boot the chip will either show disabled on screen or you'll get a black screen in the case of certain Modbo's , then tap reset and the console should boot with the chip disabled and you'll be able to use this method if you want to use FHDB without having to physically remove the chip, alternatively you can snip the power and ground points to the chip to permanently disable the chip without messing by the bios and cdvd points .

If you want to go the reprogramming (flashing) route in order to know what steps to follow next you have to be certain which clone you have , if it's a Matrix Infinity clone it'll usually say on the chip itself , same for Modbo only difference will be the absence of the clock point on a Matrix . You'll need a SPI programmer , a cheap one that I know works is the SPI CH341A mini programmer , you can try using the bios clip that comes with it but it never works for me I remove the bios chip from the board with hot air and dump the fw that comes on the chip , I then flash replacement SPI chip with the dumped fw and resolder back to board , if your fw dump is corrupted already you have to choose the correct fw to write back here is why you have to be certain that you have a Matrix clone or Modbo clone , Modbo will not boot with original Matrix code I'm guessing the opposite is true as well but I've only had to do this on Modbo's . If all went well once installed and you access the bios you'll see that upon hitting save settings you'll be greeted with a settings saved reset console screen .

If you are going to go the programming route and you have a Modbo I would be very interested in getting a copy of the SPI fw dump .

Yes I know about the hotkeys, I downloaded the matrix 1.93 instruction manual. Everything works but I cannot tell my friend to press start and reset the ps2 at every boot so better to use FMCB.

I have the Tensy 2.0 or something similar I don't know if it is usable?
But as I said I'm not experienced in these things, if the Ps2 was mine I'd have made any experiment but in this case I prefer to leave things as they are. Thank you very much for the infos anyway, if later on my friend will agree they'll be useful.
