Dell Optiplex 320 : unable to install

[CyrilleMortreux]

Hi.

I try to install Ubuntu on a Dell Optiplex 320.
- PIV 3Ghz
- SATA
- Pci bridge ATI RS480
- IDE interface : ATI SB600 Non Raid 5 SATA
- IDE Interface : ATI SB600 IDE
- USB Controler : ATI SB600 USB

1- Ubuntu 6.10

I have tried first an Ubuntu 6.10 Alternate i386 but the boot from the CD hangs up and shows many BIOS bugs (USB, SATA, ACPI, IRQ...)
I have passed some extra options at boot like :

pci=nomsi noapic nolapic

but no way to get that working.

So I have took the SDA at home to perform an Ubuntu setup on, and that worked... At home... But does not boot here.

2- Linux Rescue CD

This one works fine with a 2.6.18 kernel. I can access my SDA drive and mount my slices, or modidy then with gparted. But this is a rescue CD; not a working Linux box.

3- Ubuntu 7.04

I have download a fresh ISO of Feisty, and passed these extra options at boot :

irqpoll pci=nomsi pci=noacpi nolapic noapic

That boots, I have my ncurses dialog opening, but no way to get the CDrom recognized even if I change my Cdrom :/

4- Debian Etch daily snapshot

I have tried with :

expert irqpoll pci=nomsi pci=noacpi nolapic noapic

But no way too to get the CDrom working

What could I say more ? ... What a mess !!!
I have tried to switch off as many things as possible in the BIOS but this is a very poorly BIOS, and there is not a lot og things to do with (No USB legacy support, no Ide compatibility support...), and I just can't switch off USB support because mouse and keyboard are USB (no PS/2 din. )

Any idea ???
