How do I set variables in efishell?
Hi all,
I still do not know how to set variables in efishell to switch the console to my serial device.
I actually know that I have to set the variables ConIn and ConOut. But I am prettty confused by any documentation I can find about actually setting these variables.
Any help appreciated
Christoph

Has anybody figured this out yet? Specifically, there is a "set" command in the EFI shell, but the difficulty seems to be figuring out the device path to actually set the variables to. Then of course this early firmware may end up ignoring them anyway. Thoughts?

From what I can glean from the docs and my hacking, a set in the shell sets a shell variable, NOT a root EFI variable. The only way to set the EFI variables is to do so from a C app usinf the EFI toolkit. This is a bit unfortunate as it means one can not add/edit menu items from the shell prompt. Also, typing exit at the prompt puts you into the boot menu, but AFAIK there is no way of getting back to the shell.

Tim Riker - http://rikers.org/ - short SIGs! <g> All I need to know I could have learned in Kindergarten ... if I'd just been paying attention.
Plus the fact I haven't found a single version of the firmware which actually saves these variables. So setting them tends to be useless.
It hasn't been too important so I haven't followed up on it with Intel.

Yes? I've saved variables from one reboot to another. I was using a workstation (bigsur) with 0.29 PAL, but it worked for me.
note also there is a dmpstore command which shows all the variables.
