    Do you have the Xbox connected to your home network? Do you know the IP address the Xbox was manaully set to or being assigned by a DHCP server? Can you FTP to that IP address?

    I hate tracking down traces on these motherboard images. I need to print out some 2 or 4 x sized acetates of the top and bottom side of the motherboard images since my laptop monitor isn't very big to see a large enough region of the motherboard when blown up. Line up the two acetates so I can see through from the top to bottom side of the motherboard.

    Update: Q7R1's generating the stronger PCI_RST* signal to drive many other chips on the motherboard. The MCPX can't drive them all without it. Edit: There's must (may) be another transistor pack to generate the SDRAMs CKE (clock enable) line from the MCPX's active low output PCI_RST*. I just haven't tracked it down yet. PCI_RST* is held low after the console is powered on to reset all of the PCI attached devices. Once Power_Good is received from the power supply to indicate that all voltages are present, the PCI_RST* line is released (goes HIGH) to allow the system to exit the RESET state. There's also a similar RESET line (CPU_RST*) from the NV2A that's released after the PCI_RST* is released to allow the CPU to start working. Q7R1 is most likely an MBT3904DW1T1G dual NPN general-purpose transistor pack. From the lableing on other transistors (Q id'd parts) on the motherboard which are MMBT3904s - general purpose NPN transistors. There's also the MMBT3906 on a v1.6 motherboard - general purpose PNP transistor. package labeling should read MA followed by the date code letter(s). On-Semi datasheet: https://www.onsemi.com/pub/Collateral/MBT3904DW1T1-D.PDF Update 2: The two vias where pin 4 would be in the LPC Debug port are the PCI_RST* signal, via closest to pin 2, from the MCPX chip and the buffered/strengthened Buffered_PCI_RST* output, the via closest to LPC Debug port pin 6,, from Q7R1's pin 6.

    From the bit I've found on the RESET of the Xbox hardware, the signal comes from the MCPX chip. I'm not sure what Q7R1 does. A transistor pack of some sort. Is there any marking on the top of it?

    From what has been reported, it seems that the MCPX doesn't output a the LPC clock (pin 1) on the LPC Debug port if pin 5 of it is LOW. Something somewhere on the motherboard is keeping this RESET line pulled LOW instead of allowing it to go high after initial power on. Is pin 1 of the IDE connector also at 0.15 Vdc?

    For a 2TB hard drive, It will save space if the game has a lot of files smaller than the 64KB cluster size. Each file smaller than 64KB's will occupy 64KBs - one cluster - the minimum space that can be allocated to a file on a huge partition - greater than 512GBs in size.

    I've been trying to track down a pull-up resistor connected to pin 5, LRESET#, of the LPC Debug port but have not had much luck. I haven't found one like I see connected to the LAD[0..3] lines.
  9. KaosEngineer
    Which version of motherboard is this being measured on?
  10. KaosEngineer
    Pin 1 is actually a 33MHz clock signal. Your multimeter may not translate it into a voltage level of any kind as it is not one. Pin 5 at 0.15Vdc ??? appears there may be a pull-up resistor missing/broken on the motherboard near the LPC Debug port. Won't work with the LRESET# always LOW. The LPC bus is stuck in a reset mode.

    There must be another character in the name that it doesn't like other than the hyphen.

    Do you have a USB-to-HDD Interface adapter and SATA hard drive so you can use XboxHDM23USB Beta 2 or 3 to build a new locked hard drive for the Xbox? When installing an IDE-to-SATA adapter/SATA HDD combo in the Xbox, you'll also need an 80-wire 40-pin, 24" preferred length, high-speed IDE cable.

    The power supply unit is never completely off. It has a section that is always on when AC power is connected. It's the standby power for the clock circuitry and System Management Controller's soft power on/off for the rest of the console implemented in the Xyclops chip for a v1.6 or PIC processor for a v1.0-1.5 revision of the Xbox.

    You need to make sure that the X3 BIOS's Use Saved Partition Table option is enabled. https://imgur.com/a/wZOUOov

    The MN-740's power supply brand and model number are Foxlink Model No: FA-4F020. Input: 120VAC 60Hz 13W Output: 6.0VDC 1.0A Here's an non-blurred out picture (still a bit blurry from my old camera though) of the labeling on the one I have: I found these measurements online at a couple of places listing these power supplies for sell. ($23 and up) 1.5 x 4 x 8.4 mm 90 degree angled plug. Edit: Ok not as i first thought, 1.5mm I.D., 4.0mm O.D. by 8.4mm long right angled jack. Guess I should have taken a picture of the plug too and posted it. Edit 2: Although I'm not sure of the I.D. dimension as I only find 1.7mm not 1.5mm 4.0mm O.D. barrel connectors. Found a less expensive source $12.18. They may make up a difference with higher S&H charges. https://www.capoweradapter.com/new-foxlink-fa4f020-ac-adapter-6v-1a-1000ma-fa4f020-p-804.html

    Are you measuring the voltage level of pin 5 (LReset#), 0.15Vdc, with the modchip connected?

    The FATX filesystem has a limited allowed character set: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!#$%&'()-.@[]^_`{}~ (including the space character) No comma allowed.
  18. KaosEngineer
    There are two types of ISO files available on the Internet for Xbox games: XISO-format dot iso files and redump archival dot iso files (usually larger than 4GBs). The later cannot be stored on the Xbox's hard drive due to FATX's 4GB maximum file size. You have to extract the XDVDFS portion of these ReDump-style disc images and either upload the extracted file set as is or create an XISO disc image and use the attach app and XISO mounting option of softmods or install the hardmod BIOS patcher to add the same hooks into the kernel to mount the XISO-format iso file.
  19. KaosEngineer
    Yes, something bad will happen once you hit the point of writing over 1TB of data to the drive. Previously written files and folders will start disappearing - corruption of content already written to the drive.
  20. KaosEngineer
    And, if the console is softmodded with Rocky5's Xbox Softmodding Tool, its Extras Disc ISO file from the Build 1.1.7 / Extras Disc / subfolder at the prebuilt google drive repository.
  21. KaosEngineer
    Kernel version = 1.0.5035.1 means it has the X2 5035 BIOS booting from the modchip.
  22. KaosEngineer
    what's the error code you get when booting from the other bank?
  23. KaosEngineer
    BIOS Checker 5.0 doesn't have enough MD5 hashes in it's configuration file to help much. Almost if not completely worthless as it is.
  24. KaosEngineer
    Look in the dashboard for the Kernel version knowing that value can help ID the BIOS version. If it has an Evox shield on the startup flubber animation it's an Evolution-X BIOS version. If it has XECUTER2 under the big X logo at the end of the animation a Team Xecuter BIOS. or Xecuter Rox My Box - X2 5035 or X3 BIOS (X3 BIOS only for X3 modchip)
  25. KaosEngineer
    I total missed that. I saw it but it just didn't click.
