    Hello there, i bought a new SSD of 256 king, and i been trying to fresh isntall with rufus MBR, and still perfect, and then said Reset in 3..2..1.. and then i get an error saying:

    the operating system could not be loaded because the system registry file is missing

    something with a file .efi

    I been trying all the command but still no works, btw the another partition, the internal one is working fine still.. but i can not boot from the one i want to install, also in the bios in security i can see my SSD but no in the boot part, just getting the UEFI boot loader or something like that

     

    Help please 🙁

    Hi i’ve just got a 737A with bios rev:

    BIOS Date: 11/07/2018 10:07:49 Ver: 3BANS010

    and i think it’s a late revision. (and a beta one, because on boot it writes “EVALUATION COPY”)

     

    i d’like to have unlocked features ’cause my 737A is sold with 256GB SSD and i’m sure the 64GB eMMC is still on the board but disabled in bios so i want to enable it to get a second linux drive.

    Can you share what are the menu ID you’ve enabled?

     

    thank you

    You need to flash your bios chip from a programmer box through SPI bus… You can also use a Raspberry Pi with the flashrom utility package on the SPI bus… I have done this on some corrupted bios chips I had to recover…

    My first advice is to not alter your bios if you are not confident in what your are doing and not aware of how to do it the safe way !

    Can I flash my BIOS chip with CH341A?

    Do someone knows how to use it?

    Does YEPO or ez book 3 have CMOS battery?

    It should be possible with CH341A, but never used it so for 5 bucks, you should give it a try… There is no cmos battery, the main battery cable is maintaining settings, disconnect it and you will have your bios reset…

    Try to locate your chip and find the datasheet for it… Pinout is very important to not destroy the onboard chip with bad voltage input… If you don’t have skills to rework your board on failure with a new chip and a hot hair station, take care of it ^^ Common brand is Winbond or so… Good luck…

    Look at the attached pictures

    What is the Winbond?

    What .ROM or .BIN version of BIOS to use?

    Use drivers and soft in zip files attached or ask for particular softwares from the vendor you will buy the adapter from ^^

    Go to my Drive folder, you have original and modded bios there : https://drive.google.com/open?id=1NDw2nXCUaaIh1uRSG9W8PMrispqMlvuS

    1st page you have the link to 737A_DRIVERS in my 1st post… You have all drivers and bios files related to the 737A I found on the web…

    Google it, you have plenty of tutorials about it… You can flash directly the yepo rom file at address 00000000h (0h) of your chip with some software tools (SPI tools) and the usb programmer… The rom file is compatible with the GigaDevice chip as shown in the Intel ME VSCC table in the rom (see attached picture)… There is no AMI capsule on it so you can directly write this rom file as is on your chip…

    You can try flashrom from a linux distro to do it easy if the chip is compatible… You should try to write it with the Winbond chip with the -c setting if it is not, that should work because it is supported in the VSCC table…

    https://www.flashrom.org/Flashrom

    You can see me using it in my attachments in the post here : https://techtablets.com/forum/topic/yepo-737a-running-jumper-ezbook-3-pro-v4-bios/page/4/#post-151789
