console in UEFI boot

[karu.pruun]

Hi Bernie

I don't know. Do you mean your machine is 64bit but has a 32bit EFI? This
is a good overview of UEFI

https://www.happyassassin.net/2014/01/25/uefi-boot-how-does-that-actually-work-then/

I think the terminology is that the type of your firmware is either BIOS or
UEFI, and the latter can emulate BIOS boot if needed.

I should also retract my original complaint: booting now works fine on
macbookpro even without interfering, ie setting 'mode 0' at loader prompt.
No idea why the error is gone. All I did is correct the vfs.root.mountfrom
variable so I don't need to enter it by hand in the middle of the boot
sequence; and delete /etc/issue left over from the boot CD. In any case,
the problem now is that i915 does not load; the machine gets stuck.

Cheers

Peeter
