In some situations, the BIOS may become corrupt, whether it be a failed BIOS upgrade, power outage or surge, or a malicious attack from a virus. A corrupt BIOS results in a failed boot up process and the BIOS will not load the Windows operating system. If this occurs, you will receive a notification on the startup screen when the operating system is being loaded. In cases like this, the BIOS recovery RCV file is used as a backup to boot up the operating system.
On some Dell computers, there are two files (BIOS_PRE.rcv and BIOS_CUR.rcv) that can be found in the EFI system partition. In this case, the files are located in the dell\bios\recovery\ EFI partition directory.
NOTE: If your computer does not boot up from the BIOS recovery file, the computer may not support the recovery function or there may be an issue with the hard drive on your computer.
Common RCV Filenames
BIOS_IMG.rcv - Name of the RCV file used by select computers to replace a corrupt BIOS and complete the boot-up process.
What is RCV BIOS? I assume this stands for Recovery BIOS?
@n0xlf mentioned a file (BIOS_CUR.RCV). Where do I get this from?
Just to be clear, I am on 1.10.2 BIOS version. I have downloaded the latest 1.11.2 from Dell website. It is in the form of an EXE file (Precision_7X40_1.11.2.exe). Now, can someone provide exact steps to do this? From what I understand, we are to get the file from P:\EFI\Dell\bios and replace it with the file from Precision_7X40_1.11.2.exe ? If so, how do I get the "BIOS_CUR_RCV" from "Precision_7X40_1.11.2.exe" ?
The contents of the "Precision_7X40_1.11.2.exe" file is comprised of these files:
.data
.rdata
.reloc
.rsrc
.text
CERTIFICATE
[0]
That [0] file is the one that has 16MB which I assume it's the contents of the BIOS. So, from my understanding of the previous posts, I should rename this file to "BIOS_CUR.RCV" and place it in EFI\Dell\Bios\Recovery", then press the power button for 30s to initialize the recovery through this file, but I feel that I'm missing something in the process.
Kindly clarify if the steps above would work.
