Normally if we want to change Bios Setting, we need to restart the PC and when system boot up we press the hot key (F2 or F10) to go "Bios Setup", then change the setting.
However, I would want to do real Bios Setup from Window Environment...Is it possible to copy the image of Bios (of my computer) to a binary file? then setup a virtual machine to run it and do all the changes? If it is impossible with existing tool (VirtualBox, Qemu,VMWARE)...is it possible to write a special virtualization software to do that?
Thanks

Quickly press F2 (in OS X or macOS, press Fn + F2) to enter the VMware BIOS. The BIOS boot screen is visible for only about one second. Make the changes you want to the BIOS settings, and then press F10 (OS X and macOS: Fn + F10) to continue starting the guest OS.
To enter the BIOS setup for the guest operating system, click VM > Power > Power On to BIOS. Note: For newer Workstation versions, click VM > Power > Power On to Firmware.
You cannot boot into the virtual BIOS. You change the settings of the vm from the VirtualBox Manager while the vm is shut down (Settings|System).
In the VirtualBox machine selection, click on the virtual machine you want to enable EFI in, then click Settings. Switch to the System tab and check the box that says Enable EFI (Special OSes only). Linux is pretty special, right? Now you'll be able to boot and install a Linux virtual machine using EFI in VirtualBox.
Go to your settings of the virtual machine go to system > motherboard click EFI on
Boot your machine and type in the shell (you need to wait a bit)
"exit" then you will go into the BIOS EFI if you want to quit hard power it off and to turn off the bios for boot again reverse the settings...
(For virtualbox)
