Yeah, I know what you're thinking, "PC Chips, are you out of your mind?!" I don't care, I had this board laying around with a dead AMD K6 in it and even with a different CPU, the motherboard still refused to work. Turns out the BIOS was corrupt, so after finding the latest BIOS for the M575 on an Italian website(or Spanish, I don't remember exactly), I flash the BIOS into the ROM chip using my ROM programmer, and sure enough, the board works.
Of course, I know PC Chips' products are a giant mound of garbage, but what made me want to fix the board was the sound card integrated on the motherboard. It's a rebadged C-Media CMI8330, the SoundPro HT1869V+, and I know several people on here have made mention of the CMI8330, so I wanted to see how good of a SoundBlaster 16 clone the CMI8330 is. There is one problem, however: I can't find the pinouts for J4 on the motherboard, which is where a separate piece bearing an audio output, line in and microphone input as well as a Game port plugs in to. Here's a page on Statson.org detailing everything on the motherboard:

Does anyone happen to have the pinouts of the J4 header? I'm looking to build my own Game/sound module with at least 2 RCA jacks and a Game port(and possibly a WaveBlaster header if it's at all possible - inside the computer, of course), but without the pinouts of the J4 header, I can't do that. I need to know which pins carry the audio outputs and the signals required by the Game port.
Oh, and one last question: is the cache on this board real or fake?
