Dell optiplex 3000 micro bios

Compare a locked and unlocked bios with a hex editor. If you can`t do it yourself post your backups and the PC service tag

I have found some HEX apps to allow me to compare 2 files, and I can modify them as well. Is there a good guide or some way to learn what the different parts of the BIOS are and what the HEX does to change them? Trying to figure this out on my own if possible. Thanks!

Thank you for the link! I guess I should have clarified that I did look through the info at that link, before posting my question earlier. I didn't see anything there that lead me to any tools that I could use to make the necessary changes to the Absolute feature within my BIOS. Do you have any iformation for that? Thank you!

I just picked up a Optiplex 3000 Micro and it has the Absolute feature enabled. I want to permanently disable this option. I plan to dump both BIOS chips today, and I can post the files to have someone do the work for me. However, I would also like to learn how to make the changes myself. Are there any resources or tutorials specific to Optiplex Micro or Dell BIOSes that someone can point me towards? Also, I just wanted to confirm that I need to dump the 25B128ESIG (16mb) and 25R256EYIG (32mb) chips. Thanks!

Thank you for checking I have read the bios files again. This time I believe its
correct, please see the attachment.


FYI if anyone is struggling to read MX77L25650F

I used CH341A

I had to add the chip to the database of the CH341A Programmer V1.03 by adding the line in the chiplist file.

<MX77L25650F id="C27519" page="256" size="33554432"/>

Hope this info is useful for anyone with the same chip.

Hi what connector did you use? sop16 to dip8?

Re: Dell optiplex 3000 micro bios

put back 32Mb as is and write only 16Mb

Thank you.
Password has been removed, but absoluted has not. No problem, with Dell's bios, absoluted can be turned off if you use windows for 3 days.
