Bug Description
Testing:
testing 12.10 beta 2 on spare IBM thinkpad t41 outputs following error on startup:
"
This kernel requires the following features not present on the CPU:
pae
Unable to boot - please use a kernel appropriate for your CPU
"
Proposed problem:
The only LiveCD supporting 32bit processors requires PAE. This makes the LiveCD not work for 32bit processors not supporting PAE, while the benefit is making 32bit processors with PAE support support more RAM. Effectively the LiveCD makes life a little easier for people slightly newer old 32 bit computers if they have alot of RAM for a 32 bit computer or it prevents it from starting if their computer's CPU does not support PAE, physical address extension.
12.10 beta 2 + 32 bit CPU without PAE = not Ubuntu user
12.10 beta 2 + 32 bit CPU with PAE = Ubuntu user with access to 4GB+ RAM out of the box, if they have that much RAM
12.10 beta 2 + 64 bit CPU = Uneffected
Proposed resolution:
Change the kernel package on the LiveCD to the one supporting 32 bit processors but not requiring PAE
New LiveCD beta not requiring PAE + 32 bit CPU without PAE = happy Ubuntu tester
New LiveCD beta not requiring PAE + 32 bit CPU with PAE = happy Ubuntu tester which has to install kernel after install for access to greater then 4GB RAM if they have that much RAM
64 bit CPU = Uneffected
