lenovo thinkbook 15 g2 itl disable onboad ram bios

[deejay_xb]

I have a lenovo thinkbook 15 g2 itl (working!) and in the .bin bios file i found the lines with 6.5.6.5...6, but i don't know what to replace with 00 to disable the onboard ram/memory, if someone can help.

i've attached the extracted .exe file, this contains the bios dump when opened with 7zip (the file is DOSFLV34_QS.bin)

also how to flash the modified bios? can it be repacked and flashed?

Your backups aren`t good. Are you using a clip. What model is your programmer and software version

I'm not using clip,using CH341 and NeoSoftware V2.2.0.8, i also saw that something is not good with the dumps but never had problem with CH341 and Neo
Maybe something Happened with programmer,can you try now?

[nikovmiroslav]

I tried again,can you saw now?

Still not good...

"FfsParser::parse: not a single Volume Top File is found, the image may be corrupted"

Your dump will be good when at address 0x0099E210 you will have something like this:

Thank you,probably the dump is corrupted,i found the dump that works and onboard ram is disabled,but it has no serial number and didn't recognize my SSD disk at all,if you can rebuild this dump i will be grateful.
Serial number is: MP23P95S

Your files are too corrupt to repair or get any DMI or key from.

Try these.
