Need AHCI for Dell Dimension 8300 BIOS A07

[Arno500]

Hi,
I'm new on this forum and I want to use AHCI. But I have a little problem. My BIOS doesn't have AHCI. - LOL - . So can anyone patch my bios to have AHCI option ?
And if you can ( if you have time to waste ), can you add USB boot too ?
Thanks a lot,
Arno

I used to have one of those. It has the ICH5 which doesn't support AHCI. It supports USB booting already, though.

I also have the model that replaced it, the Dimension 8400, which has AHCI and lets you use it right away.
