@superb123 - Did you already try to disable BIOS lock on this system, via setup_var or RU method?? If not, do that first.
No, do not add anything to SCEWin

Here is variables you need to change to 00, if either is 01
BIOS Lock, VarStoreInfo (VarOffset/VarName): 0x9BC
Flash Protection Range Registers (FPRR), VarStoreInfo (VarOffset/VarName): 0xFB7

Use setup_var method (rename .efi file to Shell.efi), you can start at step #6, I've given you info from 1-5 above
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash
Alt boot to grub when no boot to EFI on exit page - [Help needed] Hidden Advanced menu Bios HP Z1 J52_0274.BIN (2)

Or RU method, this may be easier for you, due to how this Dell BIOS is - Go to section 2.2 and make bootable USB with RU program, then read 2.3-2.5

Dear All,

I have an XPS 9370 which is not turning on. All i can reach is the display test.
I think it has bios issue.
I have dumped my BIOS with CH341 Programmer.
I have seen a manual / few post how to make a clean bios i believe Lost_N_BIOS wrote it somewhere but i can not find it now.

If anybody can please have a look at my bump if possible tell me how to clean/fix it.

@Lost_N_BIOS

Can someone please extract (BIN files to be flashed) this bios for me? I am looking for 4MB and 8 MB BIN Files which i plan to flash directly using CH341 Programmer.

Hardware :Dell Latitude 3330. BIOS Version A13. My current BIOS Version is A01 and i am not able to update BIOS from Windows as well as USB DOS bootup. All goes well with no error but after auto boot , system simply boots into windows 10 without updating BIOS. Tried disabling Intel Virtulisation etc. but BIOS simply doesnt get updated.

I am looking for upgrading to A13. Exe file is available at https://dl.dell.com/FOLDER05122121M/1/3330A13.exe. But i dont have 8 and 4 MB BIN files for this. Can somebody pls assist with 8 and 4MB A13 version using this link?

I have tried multiple methods including PFS. However, not working out.

Dump of my existing working BIOS A01 is attached.

Thanks.

I need help too to extract HDR and ROM files from Dell Inspiron 17R SE 7720.
I tried the /writehdrfile and /writeromfile commands with all bios available on Dell site, but I always received errors.
The only thing I managed is to extract is the CAP file but I can't use it for bios recovery.

Someone managed to recover the above files to recover a roasted 7720?

#309 RE: How to extract contents of this Dell BIOS package? by lfb6 21.02.2021 13:24

You can extract a bios region from the cap file, but that's not a complete bios. You'll need a complete and 100% valid dump of your original bios chip with a hardware programmer (CH341) to recover board-/ machine specific data and for the other UEFI firmware regions.

#310 RE: How to extract contents of this Dell BIOS package? by gario 13.06.2021 03:18

I can't get the PFS extractor to work on this Dell file \BIOS_V134X_WN64_2.9.0.EXE

I can't get WINRAR or 7z to work either

/writeromfile command throws an error

Can someone please help me get the ROM files so I can mod the BIOS in MM tool? My objective is to get my R520 to recognize the nvme drive on the pcie card.

Hi All,

Following on from the thread:
DELL XPS 8500 Vostro 470 Socket LGA1155 Motherboard NW73C - Wont see or use all Memory Slots

I made the mistake of thinking maybe going back to an earlier bios (A05 A06 etc) and then updating thru each once up to A14 via AFUDOS may resolve the issue. Instead the board refused top boot. Fans spin and board just beeps.

After some research I read that maybe the bios chip can be re-programmmed using a CH341A programmer. So I ordered one. I happened to find a replacement identical board on eBay as well (same board and it works fine with 16GB+ memory). Although I still wish to fix the original board if possible.

I understand from what I have read that all the CH341A programmer software 1.18-1.34 /Flashrom/AsProgrammer_1.4.1 all require a bios.bin file.

The Dell bios's come as packaged .exe that contain a BIOS.ROM and a few other parts (ME etc) (up to version A06 or A10 I think) and after that its a BIOS.CAP.

Anyway I though I could create a BIOS.BIN from the working board. Unfortunately the SP1_1 chip on there is a MXIC MX25L3206E and I cannot read this chip to get a copy of the working bios. No software that I can see will read this chip. I have read that the CH341A may require the voltage mod from 5V to 3.3. ? I will look into this. I need some tiny wire and a soldering iron and a big magnifying glass :)

The bricked board chip is a PCT25VF032B which seems to get detected as a SST SST25VF032B. I can read it but I just need a working BIOS.BIN to flash to it.

Can anybody please help me by explaining how to create a BIOS.BIN that I can use with the CHA341A Programmer or has a pre done version that can be posted? Not bother which version as I should be to get online and update later if needed.

I have uploaded all the DELL BIOS's from the website on my MEGA.NZ page. I have also (I think) took a copy of the bad bios from the non working board in case that can be fixed or if we need any /Asset No/Serials/MAC address pulling from it. Well if that is even possible?

https://mega.nz/folder/EFtGVaob#sguZAu48jF06WwAdnhr72g

Hoping somebody can help with this. Thanks

Kind Regards,
Kenny
