[ubuntu-za] Kernel panic - 12.10 on Dell GX520

[Robin Bownes]

Hi all,

I'm close to my wit's end with this problem, I hope someone can help.

I am trying to install Ubuntu 12.10 (64 bit) on a recently acquired, 
small-form-factor Dell GX520 (Dual-core Intel, 1GB RAM). I have been 
unable to even get the installation to run through completely before 
being kicked out to a screen full of text (looks like considerably more 
than one screen's worth), the last lines of which, mention "kernel panic".

I've Googled this and have seen a few others that have experienced 
similar problems, but have seen no solutions.

Help please - simple as possible please, preferably with explanation. 
(for my learning curve)

Thanks.

Robin
