Have a look at rpi-update too - it has code for switching the start.elf version, and I added the code for detecting the current start.elf split being used :)
No reason you couldn't factor it out into a standalone script.

And going back to the original topic of a boot menu - see viewtopic.php?f=24&t=8059

Has anyone done any testing on memory splits between 128 and 196 ? I can easily create Arm144 start.elf and arm160start.elf, and it looks good on the linux side, but I cannot get any sensible results from "vcdbg malloc" to know how much is free on the gpu side. :ugeek:

EDIT: There is enough info in the vcdbg malloc to tell me that I am not getting any extra VCore Ram, as well as corrupting the linked list. So that looks like a dead end.

This post explains it quite well

In short you boot off start.elf but there are other files in the boot dir to choose a split edit the config file to choose the one you want - the post above does better justice to how it works
