Matrix On A 1.6(b) Xbox
Posted 05 December 2004 - 08:15 PM
My LPC rebuild looks like this;
I then cut the LFRAME trace and soldered in 2 wires for each side of the cut, which go to a switch for enabling/disabling the M$ bios/mod chip.
Now in all the tutorials and threads I have read, they all say to ground the LFRAME, AND there is no D0 point on the 1.6( xbox. The X3 1.6 rebuild PCB has a D0. And this pic shows a D0 as well.
I haven't connected the D0 to the matrix, and I haven't grounded the LFRAME. Here are some pics of my matrix install on a crystal clear 1.6b xbox.
NOTE: I have soldered the pogo pin 7 on the matrix (LPC pinout #3) to the switch for the LFRAME. I have removed pogo 7 and D0 pogo.
Now that I have got this far. I'm having sound/video freezing problems. When I power on sometimes there is nothing on the screen, but if I hit the eject button, away it goes loads up the dashboard. Sometimes the video freezes, sometimes its the sound & video, and yet sometimes, it boots up perfectly fine. When it does freeze and I hit eject it skips the flubber anim shows the X logo and loads the dash. But this only works half of the time. I have flashed the matrix with the Yoshinio evoxM8 plus16b memory fix bios. Is it this bios causing these problems? Will the latest X2 bios work in the 1.6b xbox? And why is it that when I did exactly what everyone said NOT to do that it worked? And yes it FRAG'd like crazy when I grounded the LFRAME. I may yet rebuild my LPC according to the X3 rebuild PCB if changing the bios doesent solve this video/sound freezing problem. Any help/input/comments/suggestions is greatly appreciated. Thanks for everyones help.
My dip switches are set to mode 2. 1 off 2 on. Although mode 3 and 4 will still work. I have flashed from evox in mode4 and havent tried mode 3.

 my switch pic is wrong, the middle lead on the switch goes to below the cut on the LFRAME, the left lead to above the cut on the LFRAME, and the right lead to the matrix pogo 7, in other words, swap the yellow and green lines in the switch pic.

I hope this clears somethings up.

Reason the LFRAM was grounded was becuase of the fact the LFRAM was not compadable with the matrix. I am guessing that the newer bios might have something to do with the booting of the LFRAM but not 100% sure.

Simple correction would be to reinstall msdash from a slayers install cd.
Complex fix would be to examine your backup files for dates and sizes and find the correct file that was changed if a file was changed and recopy it back over.
In closeing. I am guessing when you grounded LFRAM you had removed pogo pin 3 and you also had nothing soldered to the pogo. If this is correct then I am guessing grounding is not working for ya.

Here are the SST49LF020 specs I was refering too.
Also, just wondering pins 1,22.26,27,28 on the chip say NC, what does the NC stand for? something like N/A?

The chips are made to fin into a socket and so there will be extra pins now I know this chip was soldered but the spec of the chip was for a socket.
