The saga of my Abit AB9 Pro motherboard continues.
The Ubuntu 6.10 server beta installation CD recognises the CD drive on the JMicron SATA/PATA interface - hurrah!
However it didn't initially recognise the hard disks on the Intel ICH8R SATA interface, turning on AHCI in the BIOS fixed this though. (Strangely the Suse installation recognised the hard disks without AHCI turned on).
So now I'm installing Ubuntu 6.10 beta, I'll probably upgrade to the proper 6.10 when it arrives but the beta will allow me to play for a while at least.
A couple of questions:-
Is there any peformance penalty using the AHCI BIOS?
Why doesn't Ubuntu Desktop 6.10 beta work in the same system?

AHCI is a VERY well published standard by INtel, and from what I've read, AHCI is the preferred mode if you're rtunning in native SATA mode.
I've beren running a MythTV box with software raid 1 using AHCI mode with no problems at all for the past year.

OK, thanks, so that's a non-issue at least.
I *think* the Ubuntu Desktop version not booting may be because it needs some disk space to unpack the CD contents and I was trying it before I switched on AHCI mode. The Ubuntu Server version doesn't have the CD contents compressed into an archive format so it got a bit further and then told me it couldn't access the hard disk which made it clear what was wrong.

Just a comment (perhaps for future reference). I've found the Ubuntu Live CD very useful when there are "kit problems", since the CD has a good spectrum of driver modules from which it can select, according to what it detects while booting.
Best wishes, Ted.

Ditto the Gentoo CDs.
Cheers, Laurie.

...and Knoppix, which I've had boot up some very strange setups that were troublesome in everything else I could lay my hands on.
