    No.

    It does still look like a simple PLCC32-to-DIP32 adapter. Nothing fancy or special about it. Edit: However, as @Bgsmods59mentions, he had problems with his adapter like the OP's. There may be some bad solder connections between the PLCC32 socket and the adapter PCB.

    Ok, I don't have an XGecu programmer. I was not sure which PLCC32-DIP adapter they provide/use.
  4. KaosEngineer
    Hmm, did you buy the adapter from XGecu with the programmer or later from somewhere else. I don't know if XGecu's adapter is a simple PLCC32 to DIP32 adapter. From the programming software screenshot, it looks like it is.

    For the Xgpro software, press the ID Check icon. The device's type should be displayed. It may be an SST49LF020A instead of SST49LF020.

    When in the Xbox, what software did you try to use to reflash the chip? What was the error it displayed? Try Evoxdash's Flash BIOS menu option. It will display the device's Manufacturer and Product ID values.

    Check the voltage level between pins 2 (+ probe) and 3 (- probe) or 2 (+ probe) and 1 (- probe) of the the PWM fan speed controller. The FANPWM control signal is an output of the PIC processor (System Management Controller) at pin #13. It is a digital signal. To view it, use an oscilloscope or logic analyzer.

    The first 64MBs has to be good. IIRC, XBlast OS's RAM test only tests/checks the additional 64MBs installed when a 128MB upgrade is done. There is an Xbox application, xbmemcheck, that tests RAM but if your console is not even booting to a replacement dashboard, you won't be able to run it. xbmemcheck.rar Edit: You may be able to run it by creating a boot disc with this app. Make an XISO disc image with QWIX or C-Xbox Tool then burn it to DVD-R media. Buring to CD-RW media may work if your Xbox's DVD drive is one that can read them. The Xbox BIOS attempts to load/run the default.xbe file read from the DVD drive before loading the dashboard off the hard drive.

    Xeucter2 BIOS Manager (X2BM 2.3 is the last release.) You need a short ( less than 3 foot long I believe was mentioned somewhere; however, I believe I used a shielded cable that was longer) 25-pin straight through DB-25 printer cable, not a serial cable.

    XBlast resizing a BIOS will write 4 copies of one BIOS to the 1MB flash of the X2.6CE modchip. You will have the same BIOS on both banks. That's just the stupid way the X2.x lite modchips work. Edit: The BIOS you flash fills the entire 1MB flash memory chip on the modchip, not a specific bank. On my X2 pro modchip, you selected the bank you wanted to flash (one of the 4 256KB banks or one of the 2 512KB banks or the entire 1MB bank of the modchip) and flashed it with the correct size dot bin file. Edit: Actually with Evox it didn't have to be the correct size if the selected bank was 512KB and you were flashing a 256KB BIOS it wrote it two times to fill the entire 512KB bank. If you create a 1MB file with 4 separate BIOS concatenated together you can select each one separately using the bank select switches for the 4 256KB banks.

    Ok, that's good. No problem with the late reply. Next Step Look for any extraenous solder splashes or tiny balls of solder on the surface of the motherboard or between chip pins that may be connecting two or more traces or pins of a chip together that should not be.
  12. KaosEngineer
    You must create a 1MB-sized (2 x 512KB ) resized BIOS dot bin file to flash an X2.6CE modchip. When flashing the modchip, it writes to the entire 1MB flash not just the single bank selected on the bank selection switch. The X2.6CE has 2 512KB banks so you have to resize a 256KB sized BIOS, like the majority of original and modified BIOSes are, to 512KBs then contatenate two of these BIOSes into one 1MB sized file. I had / well have an X2 pro modchip that allowed you to flash a single bank based on the switch selection but the lite modchips don't work the same way. The entire flash is overwritten. P.S. I've not used a X2.x Lite modchip to verify what I have said. I've only used an X2 pro which allowed 256KB, 512KB or a 1MB do bin file to be flashed to the modchip. 256KB and 512KB dot bin files allowed selection of a specific bank to be flashed.

    You beat me to posting the info. However I'd not read down this far in the thread before I posted.

    You are off on the required cluster sizes. Max supported Partition size | Cluster Size 256 GB | 16 KB 512 GB | 32 KB 1024 GB | 64 KB ----------These next few I'm not certain of since I've not used M8 Titan patched or CerBIOS---------- 2048 GB | 128 KB 4096 GB | 256 KB 8192 GB | 512 KB

    Check the voltage level present on the collector of the transistor at location Q7C2. It should be at a stable 3.3Vdc level. The collector is the pin on the side by itself.

    Try again later. Google has download limits in place that prevent it from being downloaded. It may remove the download restriction after 15 minutes or it may take several hours before it can be downloaded again.
  17. KaosEngineer
    The new PSU you installed has both v1.0/1.1 and v1.2-1.4 connectors. Verify that the 3.3Vdc standby level is present at the motherboard's power supply connector. (Brown wired pin on the connector below) The voltage level at the resistor that has the power button signal going through it to the SMC (PIC processor) should drop to 0Vdc when the power button is pressed and return to ~3.3Vdc when the button is not depressed.

    U6F1 on a v1.0-1.4 revision motherboard. I'm not sure what's being used on a v1.6 motherboard. The location I traced the CPU's THERMDC and THERMDA (thermal diode signals to - BGA pad AA15 and AB16) end up at an unpopulated SMD 8-pin set of pads at location U3B1. i know that the SMBus address where the supposed temp readings are being read from for a v1.6 motherboard are different than for v1.0-1.4 motherboards . The value used as the CPU temp is 5 to 10 degrees C higher on a v1.6 than a v1.0-1.4 motherboard.
  19. KaosEngineer
    Yes, the CPU has a thermal diode in it that connects to the ADM1032 dual temp sensor for the value to be read from it across the SMBus. The other temp sensor is built-into the ADM1032 which simply reads the ambient air temperature around the chip. Edit: I do not know if there's a similar temp sensor in the GPU. Originally dashboards stated that the two temps were that of the CPU and GPU. But the GPU was actually the ambient air temperature inside the Xbox by the ADM1032 chip - U6F1. Later revisions of replacement dashboards started labeling this temp as the motherboard temp.
  20. KaosEngineer
    Interesting...the THERMDC and THERMDA (thermal diode signals) from the CPU only go to that missing chip's location (U3B1). I know that the dashboard's reported CPU temp on v1.6 Xbox's is always higher than on previous Xbox revisions. And, the temp sensor's I2C (SMbus) address is different on a v1.6 motherboard. I need do more research and track down any documentation on the Xbox's GPU. Questions to be answered: Does it have a thermal diode? If so, which BGA pads of the GPU are they? And, do they connect to the Xyclops chip?
  21. KaosEngineer
    Oops wrong chip name - the MS custom Xyclops chip, not the Xcalibur video encoder.
  22. KaosEngineer
    Okay, I'll have to do a bit more tracing the signals to see if they go beyond there. You could use a multimeter to measure resistance from pin 2 and 3 to pins of the edit: Xcalibur Xyclops chip. I believe they go into it instead of having the ADM1032 chip. I'd never tried to figure out where they connected before. Odd... Edit: Oops, not thinking straight it seems. The temp sensor not integrated into the video encoder, MS custom Xcalibur chip, but the Xyclops chip.
  23. KaosEngineer
    Wait a minute. I traced the THERMDA and THERMDC signals from the CPU to the IC U3B1 pins 2 and 3. The pictures I used were component-free hi-res scans from the now defunct web site diy.sickmods.net. What is the IC at U3B1 on a v1.6 motherboard? Is it an ADM1032 just like used on v1.0-1.4 motherboards? The chip is simply at a different location on a v1.6 motherboard - U3B1 instead of U6F1.
  24. KaosEngineer
    Do you have a larger SATA hard drive installed with a cheap IDE-to-SATA adapter? Most of the cheap IDE-to-SATA adapters are slow starting after a reset and the Xbox will FRAG. If you power cycle the console, does it boot properly? What do you mean by Christmas lights: Red/Green or Red/Green/Yellow flashing?

    one of the two vias at the end of the new wire.
