Ubuntu won't find cdrom on laptop


Hello,

Here is the problem :

I try to install Ubuntu 6.10 on my girlfriend's laptop (which has no mark : assembled by the store). It's an Intel Pentium M 1.7, with 1.0 Gb RAM.

When inserting CD and rebooting, I get the usual menu. I change language to French and then try to launch liveCD ... Then it crashes, not able to find cdrom drive (but it booted on in ...)
I get the BusyBox stuff, and it says that it can't mount something because device does not exist (and this device is CDrom)

I had the same problem with alternate CD, with SuSE 10.1, with Mandriva One 2007 ... FC5 and Debian Sarge seem to find cd drive properly.

I tried to pass several parameters and combinations to the kernel : pci=nommconf, acpi=off, acpi=ht, pci=routeirq, pcinopoll, pcipoll, pci=bios, pci=nobios, noapic, nolapic, pci=nodma, ... No change at all ...
Tried to change some options in BIOS, no result ...
Others devices are OK : HD, ethernet, screen, ...

The devices that are launched seem to be launched properly and are the same as used in Debian Sarge (which works but is not suitable) : ahci, libata and ata_piix (and several others which I don't think are related)

I'll try to have a more suitable description later, but I'm not next to the laptop and it has no OS installed, so it's a bit tricky ...

If possible, I would like to avoid installing 7.04, because it's for newbie use ...

I found a clue (maybe) on http://www.thinkwiki.org/wiki/Proble...not_recognized ... But I don't know how I can tell kernel the order for loading modules (remember : it's during installation, so it's CD's kernel and I can't modify it)

Any help or suggestion would be greatly appreciated.

Thanks !

one-are you checking the checksums with it?
two-are you sure the HDD is not corrupt,
three-(just throwing this into the wind) are you using a live CD?

1) CD is perfectly fine, as checksums match (and I already installed 1 system with it)
2) I'm sure HDD is not corrupted, as I managed to install a Debian on this laptop ...
3) I used LiveCD, but seeing it wouldn't install, I tried alternate CD with no success ...

I posted a bug report on Ubuntu's Malone, they're investigating ...
