You are saying that you can make changes to the MB ROM/EPROM/whatever hardware the vendor uses, by issuing an erase command on a hard drive? I'm having a bit of trouble believing that. You might be able to trash the system on the HD to a point that it is unrecoverable. I will believe that. When you're done trashing the system you just have to reinstall the system just like you would with a clean new HD. All that UEFI crap is built into the MB in Read Only hardware. A new HD does not come with any of the UEFI files or directories already on the disk. All that is created at the initial install. Blowing them away with a remove command does nothing to the MB hardware because it's Read Only hardware. -- _ °v° /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****
