Thx.

Also, remember one of the problem I have, with ata2 going to timeout
because this port of the ICH7 is connected to a PMT ?
You suggested me to connect a disk to one of the SATA port of the PMT,
and reboot the machine to see if the timeout would vanish... I've just
done it, and here is the relevant part of the boot log :

The good news is that there is no more timeout, which is excellent !
The bad news is that the disk is not detected... but maybe I should do
something in the BIOS configuration. I'll try to have a look at this,
because connecting a disk to avoid TO without being able to use it is not
that good ;)
