What chipset, particularly the IDE chips, are on that very old network?

You may need to compile the kernel with the appropriate driver rather than the
ide-generic. I had this with a via chipset MB.

Hi David. thanks the reply and sorry for taking so long to answer.
I'm not very sure if I understand what you mean by 'IDE chips' and therefore
I'm not sure how can I find it it my system. Maybe you could explain or
inform me the appropriated command...

Not sure if it s, but my harddisk is a "Toshiba MK4006MAV" and,
according to /proc/ide/ide0/hda/driver, it is using the driver ide-disk.

Does this ?

Cheers,

Rafael
