address space.
PAE allows a 32-bit kernel to access more than 4GB of RAM by paging
small amounts of the RAM above 4GB into the memory area below 4GB. It
does not use any 64-bit technology, features or anything. It is
analagous to LIM-spec expanded RAM in MS-DOS.

Linux uses a whole different system for 32-bit or 64-bit operation.
The 64-bit version is a different download and all the programs are
compiled for 64-bit operation. If you're booting off a 32-bit CD, then
all the available kernels and all the binaries on that CD are compiled
for 32-bit.
The only way to change between 64-bit and 32-bit on any Linux distroI assume that the wipe does not have to include the home directory.
is to wipe and reinstall - or dual-boot between the two.

on the machine. I now have the choice or installing natty or oneiric. My
son's Aspire One is running very happily on natty, with none of the
stability issues I'm finding with oneiric. I'll post my experience with
natty here.
throttling works differently on Windows and Linux, so it's not
/entirely/ out of the question.
Definitely might be worth trying a few variants, then.
bit more searching, I found a true solution to the instability problem.
1. Create the file /etc/modprobe.d/ath9k.conf
Insert a single line:
options ath9k nohwcrypt=1
2. Specifically for the Aspire One 722, in the BIOS, you have to promote
the Network boot to the top of the boot priority list.
These two steps came from

Thanks to both! My netbook is now fully functional.
