  3. Hi Gurus & Khenglish, My bad I bricked by Mobo, when CH341A programmer arrived out of anxiety i clicked Auto which erased one of EEPROM even before finding a way to make programmer to show up in english. Now, I am having very hard time bringing my Mobo back to life. 1) I tried Wincrisis through USB. Out of luck as the fan itself is not kicking in after plugging in AC w/o battery. 2) Then I downloaded latest Insyde Bios(A14) available from DELL support site, opened FD file and broke the hex image after string _IFLASH_BIOSIMG by IDA into 4096KB and 2048KB and wrote them. No luck again. 3) And I tried FITC with the .FD file, and when built the image it generated two files of 4096KB and 2048KB and was so sure that it will work. But no luck again. I am not sure what I am supposed do with map file in the build folder. Can anyone please guide me If I am doing something wrong if any of the above techniques should work or provide a way out to bring my Laptop to life. Any hints/suggestion is really appreciated. Regards, Pavan.
  4. @Khenglish Thanks a lot for prompt reply. What I understand is, I can stitch together through Hex editor and do the required mod to it(such as http://donovan6000.blogspot.in/2013/06/insyde-bios-modding-advanced-and-power-tabs.html) and once done I can break them at the same offset to write it each bios individually to their respective chip. Can you provide some link/short write-up to gain Read/Write access(BIOS_CTL or similar thing) on BIOS, so that I will be able to write through ME system tools w/o needing open the board each time I do want to put back the modded one. Pavan.
  5. Hi Gurus, I own a Intel HM77 mobile for which I want to remove read/write protect to do bios mod with Intel me system tools as and when required. I decided to buy CH341A & SOIC8 clip connector to read the bios. However, I need pointers on the below points. 1. My mobile seems having two bios chips reported by fprw64 as EN25Q32B EN25QH16, which I succeeded to locate on the motherboard and thanks to all the info readily available in forums. But I am not sure how can I read contents of both chips individually and have it back as a single bios image. 2. And anyone having modded bios that may fit my mobile or provide me a link where some info can be grabbed to take off the read/write protect in the flash descriptor region(BIOS_CTL?) to burn it back to my mobile again into two ROM's?? Thanks in advance for your kind help! Pavan
