NVRAM File Extension
Have a problem opening a .NVRAM file? We collect information about file formats and can explain what NVRAM files are. Additionally we recommend software suitable for opening or converting such files.
What is the .NVRAM file type?
The 'VMware Virtual Machine BIOS Image' file type and format are the default association of the .nvram extension. The extension's name stands for Non-Volatile Random Access Memory (NVRAM), and NVRAM is a special type of writable computer memory that keeps its data without power. VMware is a well-established developer and provider of multi-platform virtualization solutions.
VMware virtualization software uses .nvram files to store BIOS (Basic Input-Output System) images for virtual machines (VM's) to run upon. Just like hardware machines, VM's go through a boot-up process that starts with BIOS initialization and POST (Power-On Self-Test). Having a machine's firmware in a loadable (and editable with special tools) file serves to emulate behavior of a specifically configured hardware machine for compatibility, testing or other purposes.
A .nvram file is a binary file with a BIOS firmware image to be used by a VMware VM. Such a NVRAM file would also store all BIOS settings made from within a VM. An NVRAM BIOS file used by a VM would be locked during the entire duration of a VM session.
