Matrix Infinity shows black screen after the boot up logo with SATA HDD problem

I've recently received a SATA adapter for my PS2 and whenever I use my SATA HDD on it, it will always show a black screen after the Matrix logo (I can still disable the chip and access other Matrix options). After a few tests, I've discovered that the hard drive itself and the adapter is fine because if I access the HDD via FreeMcBoot/OPL, it can read the drive with no problem and can access the games easily.
Just to clarify, Matrix has no problem reading my IDE HDDs.

My problem now is, is there a way for Matrix Infinity to load in the SATA hard drive with no problem or is FreeMcboot/OPL the only way for me to access the drive from now on?
If it's the latter, is there a way to permanently disable the Matrix Infinity chip on the PS2 without having to physically remove it or is soldering it out the only option? I find it a hassle to disable the Matrix after every restart especially since pressing the restart button whenever a game is up would lead to the system to go on stand by mode which would then mean having to disable the chip once again followed by another restart just to access OPL.

 

The PS2 in question was already installed with a modchip when I got it a year or 2 ago. The PS2 will always boot up Matrix, regardless if a hard drive is inserted or not, when turned on and there's no FMCB or whatever required. For the hard drive it's basically just plug and play, insert the configured HDD to the Network Adapter at the back and it would automatically connect. That's all I know really so I don't know any more technical stuff.

I've only got the SATA adapter and the FMCB memory card (with OPL installed) just recently and I managed to test them out just yesterday. I don't mind opening up the PS2 and check the modchip if needed.

 

I can access OPL normally if I disable the chip. The black screen is still present regardless if the memory card is inserted or not. As for the HDD, it's already configured for the PS2 when I bought it since games are already installed and all that (same with the IDE when I bought it back then). I even reformatted it via winhiip since I thought it would fix the problem (but it did not).

Just some info regarding with the Matrix chip and the system itself just in case:
The Matrix's version is 1.99
The system's model is SCPH-50003

By the way, if ever the black screen problem still persist, it's safe to just remove the Matrix chip right? Might just stick with FMCB if it's still an issue for a long time.

Edit: Just discovered this video and it seems to have similar problem with mine mainly with the whole can't access OPL if the chip isn't disabled in the last part

 

That's good to hear regarding with the chip. I'll take a pic of it though since I don't know which wire is the power supply of the chip.

 

I've finally managed to open the system and this is how the board/chip look. Which one of the wire is the power supply of the chip so that I can remove it while keeping the rest intact just in case

 

Is removing the wire from the chip good enough or should I also remove the wire connected to the board? Also, is cutting the wire good enough or is soldering the only way?

After some delays, managed to disabled it. Thanks for the help
