    i2ite ec read/write using ft232h

    hi all, i have i2ite written in python by c0d3z3r0. it using for read/write ITE SIO/EC chip via SMBUS. for now, i havent try it because i couldnt buy ft232h in my country. supported device to do this is(based on pyftdi):
    FT2232C/D, FT232H, FT2232H, FT4232H, FT4232HA.
    i attached the link to the i2ite c0d3z3r0 give to me. anyone here have that device above and can test it for me?
    read and write support for entire firmware of ITE EC · Issue #3 · c0d3z3r0/i2ite
    https://github.com
    hi codezero, do you plan to improve this code to read and write entire EC firmware, which is usually 128kb?

      Hi, I have succesfully read and write my IT8227E-256 with this mod without errors.
      In my case, it has worked with B interface only, so you must connect the wires correctly...

          Thanks you so much mate. my programmer also already in my country but haven't arrive yet, i ordered it via my friend when he is in Australia. my programmer is cjmcu ft232h, what is your programmer? can you explain more about B interface? and how it wired correctly? with a picture i hope. or illustration.

          btw, Codezero also made a code to dump flash region of ENE KB9022(i guess it will work with KB9012 too) using this device, but couldnt write the flash region. he suggest me to use flashrom instead. he has it in EDITOOL Github.

              Hi, I have the TIAO USB Multi-Protocol Adapter (TUMPA) v.1 with FT2232H chip.
              The FT232h and FT2232H are different chip, the 232H is single channel while 2232h is double channel, probably it will work but I'm not sure...
              Wiring on the first channel, on the JTAG connector of TIAO, has not worked, iteflash not see the EC, instead wiring on the second channel, on the SPI2 connector, iteflash has immediately found the EC and I'm able to read and write without errors. In your case, you have only one channel, so you dont have to experiment with different channels

                      Create MEAnalyzer executable from Github Python Scripts
                      by reformatt
                      Each new release of ME Analyzer only has the scripts but no executable file. It's handy for me to just run the exe in Windows, so came up with the following guide for those that might want it. Didn't see anywhere else how to do it, apologies if it is documented somewhere and I've just missed it.

                      ME Analyzer – create Windows executable from Python script from GitHub

                      1. Install Python 3.xx from https://www.python.org/downloads/ – select to add Python to PATH during installation. Current version is Python V3.11.

                      2. Open an elevated Windows Command Prompt...

                      bug of the month: write caching setting for the hard drive in device manager
                      by ChaosLegionnaire
                      i recently bought a new wd re4 2tb with 2014 datecodes. when i got around to testing it tho in victoria hd tester, the write speed was very slow at 14 mb/s with a 256 sector transfer size. when i increased the transfer size to 1024 sectors, the write speed increased slightly to 44 mb/s. read speeds and sector verify speeds were fine and at normal speeds.

                      so i just ass-u-med the drive's poor performance was due to it being an advanced format drive and i was using it on winxp. when i tried cloning my system disk to this wd re4 2tb drive and writing to it in linux, the write speed...

                      novice user attempting first BIOS write on ASUS laptop
                      by alphabetty
                      Hello first post!


                      Ok so after an (ASUSTek) optional Windows update, my old ASUS E403NA laptop rebooted and froze in the BIOS menu screen and was unresponsive so after about 30 mins I powered off and back on again. Now i just get a power LED and a black screen, I have tried all the basic suggestions and all the suggestions on the ASUS site, spoke to ASUS support who said I will need to pay for an RMA.

                      The laptop is worth €50 so I won't be doing the RMA at god knows what price.

                      So I have seen some videos where people have reprogrammed the BIOS...
