How do I install the pae kernal?

Here's as far as I got:

1. apt-get update

2. apt-get install linux-image-2.6-686-bigmem


How do I tell my TKLAPP to boot using the correct kernal?

What do I do about the following errors/suggestions?


Suggested packages:               <------what is this?            
 linux-doc-2.6.32 grub lilo                    
Recommended packages:         <------suggested vs recommended?

So I was following this guide

and that's how I got Step 1 and Step 2 in my previous post


I rebooted via shutdown -r now

ran top

and voila! there is now 8gb of RAM (only 3 or is it 4gb available to any 1 process, right?) that it? I would love to know why I didn't have to mess with grub like the softlayer article points out. Just trying to learn as much as I can, since I'm new to this.

Sugessted packages are just that - suggested... Often they include documentation relating to the software you are installing. Recommended packages again are that, often they include tools or utilities which work with whatever you are installing. FYI Ubuntu now defaults to installing Recommends.

I don't think delayed package config is no issue, and your next note referrs to the fact that it is going to select packages for installation that previously weren't (basically it's just doing what you asked).

The casper warnings can be safely ignored. Casper is for the live CD so irrelevant for an installed instance. The rest of it is Grub being auto updated so you don't need to do anything.

So yes you are right . That's it... From a quick glance at your link, it seems that tute was referring to grub (rather than grub 2).

I appreciate you clearing that up!
