The installation disk is said to require PAE, but I assume I can update safely without a PAE-enabled processor? Has anyone done this for sure?
EDIT: It turns out, after this thread was done, my processor has PAE and I didn't realize it. Some very old processors have pae.
~$ cat /proc/cpuinfo | grep pae
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pse36 mmx fxsr sse up
EDIT AGAIN: It does, however, lack NX-bit capability and has little memory installed, so there's absolutely no reason to use the PAE kernel. It runs with either the pae or non-pae kernel, although theoretically, the non-pae kernel may be faster.
