bios updates tend to require pre requisites. You cannot go from A00 to A22 in one step.  ANY antivirus software installed can brick your machine permanently. Uninstall anti virus or make MSDOS usb2 key to update bios. Updates must be run as administrator.  Its usually A00 to A05 to A11 to A16 to A20 to A22. etc. If you cannot jump from your current position the update will tell you what minimum is required to get to the end. Models that have a Micro version usually DO NOT support the Micro bios being used on Desktop SFF MT etc. Upgrading the Currently Released BIOS Images (Pr-Secure boot released BIOS) and UEFI 2.3.1  Enhanced BIOS Images (Current released BIOS)The new Secure Boot BIOS contains new features and behavior. Latest bios also prevents downgrade so be sure if you are going to change it because its a one way trip.  If it wasn't incremental the old versions would be gone. Dell Fast Boot BIOS Feature:The Dell Secure boot BIOS adds a new feature that is called Fast Boot.When upgrading from a OLD BIOS to a Secure Boot BIOS this feature will be set in Thorough mode. Setting this feature in minimal causes USB F12 boot devices/ports to be disabled in the pre-OS environment.  If you are dependent on USB2 devices in the pre-OS environment this setting should remain in the Thorough mode setting. A22 is Latest AFAIKT [URL]   [URL]   [URL]   [URL]    
Hi folks, looking for help with BIOS update. Sorry if this has been covered elsewhere but can't find relevant post. I have an i5-3570 which I'd like to stick in the above machine. I think this board is H61 which is compatible with Ivy Bridge chips but might need BIOS update. Can anyone tell me the min BIOS version required to support this chip? Currently running A11. Maybe A12 as it contains "Updated Intel CPU microcode"? Thanks in advance for any advice.
