Subject: EFI Boot Stub on Removable Media
Date: Fri, 16 Mar 2012 15:30:24 -0400 [thread overview]
Message-ID: <4F6394D0.3090104@shealevy.com> (raw)
Hello,
I am currently working on making the live CDs for the NixOS distribution
EFI-bootable with the EFI boot stub as the bootloader. Is there a
recommended way to use a boot-stub enabled kernel on a removable device
(where, AFAIK, there is no way to tell the firmware what params to boot
with automatically)? Currently, I'm hacking together a really
quick-and-dirty UEFI application that reads a parameters file at a
pre-defined location and loads the kernel with those parameters, but I'd
love a better alternative. Is it possible to embed an initrd in a
bzImage after the image is built? Or is there some way to have a CD tell
the firmware what arguments to pass to \EFI\BOOT\BOOT{ARCH}.EFI? Or some
easy tweak to the kernel source to have it use a set of default
parameters in absence of explicitly passed ones?
Cheers,
Shea Levy
