Re: Dell Latitude 7400 Bios Password
Please consider donation in support of the "Bios Requests" section of the forum.
At first boot enter the bios and input the Service Tag at the corresponding field, disable Absolute Computrace, save & restart. At the second boot, press Alt+F do exit MPM.
Good luck:----------------------------------------------------------------------------------------------------------------------------------------------------------

Re: Dell Latitude 7400 Bios Password
How did you read out this chip? I have no success with any programmer. I have CH341A, EZP2023+, RT809F and tried with neoprogrammer and as programmer too. Chip not recognized, if I try with W25Q256FV which is the same spec buffer will be empty or corrupted. Cannot read out proper data. Chip is encrypted or is there any workaround to read out?
I tried with special wson8 cable and wired up also.
Please help me!

Hello,
I have been given a Dell 7400 i5 with a locked BIOS password.
I have dumped Mac BIOS's before but I am unsure which one is the eeprom on this motherboard.
Once dumped, what else would be needed please?

Re: Dell Latitude 7400 Bios Password
I'm using a TL866ii Plus and using Xgpro v12.60, everything is making a connection, tested with a multimeter, triple checked all connections going to correct pads but the software can't autodetect the chip nor if I select the chip its detected, any suggestions on alternative software? I get "Pins Detected" but checked ID is showing 0x 00 00 00
Chip is a Winbond W25Q64JVIQ
Thanks

Re: Dell Latitude 7400 Bios Password
Sorry for another comment, does UC5 need to be removed from the board to be read? spotted there are holes in 4 traces that connect to the 2nd bios, is this maybe the reason software cant detect it? reading other section of bios also?

Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, π π π ... -
I am trying to remove the BIOS password for a Dell Latitude 5430 motherboard LA-L591P. So far I think that I have located the BIOS chip but NeoProgrammer says that is detects 3 chips. I have attached the dump from each one. Are any of these the BIOS file? Service Tag: 1DMC1T3. If nyone knows the exact location of the bios chip as well I would greatly appreciate it...
