What is not also not verified is if this is a one-way process or not. Somebody sent a screen shot indicating it is a one-way process.
I saw it, but I think it is not the same thing. I believe it was for the process of flashing the bios.
Hi That was me, the way I understand (and I hope I'm wrong)
But you are not sure, right? :-)
it is, that is the key signature option (SecureBoot) that is in my current BIOS... just one way for me if I used it.....
But you aren't sure, right? :-)
There must be other folks on the list with UEFI in their BIOSes... what options do they have?
I ever joined some UEFI event and talked to some of the bios engineer wrt secure boot options in bios. As far as I know the option varies from ODM, but in bios there would be three possible options to "circumvent" secure boot .. I saw one of the bios vendor presented these options to us. 1. Disable Secure Boot Means bios would allow files failed in authentication to execute, but there would be warning message when you attempt to do so 2. Set to Legacy or Dual (Legacy + UEFI) mode Which implies disable secure boot, as secure boot implementation requires running in pure UEFI mode (no legacy emulation module exist). This is also promise to the Windows 7 to run I think. 3. Add files to hash table Allow user manually add file hash to db and allow to run in secure boot enabled mode. But I must say it's unsure whether those options is common, OEM would custom their bios to offer different options and I think above just possibilities. Thanks, Michael
Beats me! :-[
But you don't know either, right? :-D
And you and I, and Carlos and Per and Jim are all part of "the community" - and we haven't a damn idea of how it is all supposed to work :-) .
