    NEC VersaPro PC-VRT42FBFR22B BIOS problem

    Hi All,

    [Mother board model]
    V-VE212(U3E1)

    [Serial number]
    24000135PA

    [BIOS chip model]
    Macronix MX77L12850F

    I am having some problems with the BIOS of my Versapro PC-VRT42FBFR22B.

    I extracted the BIOS file (versapro001.bin 16MB) from PC-VRT42FBFR22B ROM (MX77L12850F) using CH341A and NeoProgrammer V2.2.0.10, but I don't know how to remove the BIOS password, so I can't open the BIOS even if I boot with F2.

    I also downloaded the BIOS update package (933A0400.zip) for PC-VRT42FBFR22B from the official NEC website (https://support.nec-lavie.jp/driver/...odule_no=11756).

    However, I don't know how to extract the BIOS firmware from the package.

    In this situation, could someone please provide me with another BIOS data or extract the BIOS firmware from the attached update package (933A0400.zip)?

    Once I receive the BIOS data, I would like to update the ROM using CH341A and NeoProgrammer V2.2.0.10.

    Or, if you could tell me how to remove the BIOS password from versapro001.bin, that would be even more helpful.​

      Additional note: I also looked at "BIOS guides, methods, resources and tools", but there was little information about NEC's BIOS, which is why I'm asking this question.

                  ASUS TP500LA BIOS request/repair/merge?
                  by jbonavita
                  Hi, my laptop wont boot at all
                  With original bios no POST, only LED lights
                  With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                  Some issues
                  A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                  B- If updated from 500LN version 203 to 300, the battery stops being recognized

                  Things I tried

                  1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                  [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                  by zenius
                  Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                  Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                  Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                  by Wahaz
                  Hello,

                  I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                  So I thought it was a Bios problem.
                  I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                  Problem:
                  I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                  Initial Findings:
                  • My current BIOS version is N1KET58W (1.45).

                  • I have the ability to use command-line tools on a Linux machine.
                  Troubleshooting Steps & Conclusions:
                  • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
