After digging a little bit more, I realized that OS9 was actually recognizing the card as a 6112 card

And that OpenFirmware also

I found that lspci was giving me more information and that 6112 is the raid controller. See attached file for better reading.

I remember and old video from
dosdude1 , thanks again for all the job that you have been doing!!!) There was some issue with the card being RAID or IDE Mass Storage depending about the level of the pin 42 of the SIL3112.(around 10 min in the video)
I check that, unfortunately Pin 42 has 2.2 M Ohms to GND and 2.2 V while the computer is running.
Dosdude1, could the last picture with all the details means something to you? For me, I don not understand half of it but it could help us finding a reason why some cards cannot be flashed.
