Hello,

I'm using an Asus P5W DH motherboard, with an Intel ICH7 controler, and a Jmicron JMB363.

On the Intel, I've connected an IDE HDD and a CD-RW, no problem.
On the SATA side, i've connected 3 SATA disks, but at boot time, the kernel
detects 4 ports, and goes on timeout on ata2 :

..

Is there a way to exclude ata2 from probing ? Nothing is connected, and there
is no associated port on the motherboard...

There is something connected, I believe what's actually there on this board on that port is the SiI4723 chip which is connected to two other SATA ports. For whatever reason it gets detected as a drive, and it also seems to be not responding until we do a few resets..

The second problem is the Jmicron controler. It can act as IDE, SATA, ...
but I've configured it as IDE in the BIOS, and connected a DRD-RW on.
Problem is that IDE driver detects it, as containing ide2 and ide3, and
when probing for the DVD, I've got a lot of timeout on the command.
.. But, I'm lost in all the JMICRON configuration possibilities in the kernel :
 - it is detected by the IDE driver,
 - it can be activated in ATA/ATAPI/MFM/RLL
 - it can be activated in Serial ATA (prod) and Parallel ATA (experimental)

What should I select ?

My advice on recent kernels is just set CONFIG_IDE=n and enable PATA_JMICRON if you want JMicron support, unless you really want to use the crusty old IDE layer..
