I've tried that, but it doesn't make any difference.
I've been able to do ficticious tweaks on /dev/hdc and hdd like, for
example, activating dma mode 5 -which is virually impossible for a
cdrom drive. Actually, as I'd disabled ide/atapi-cdrom support in the
kernel I guess that /dev/hdc & hdd point to 'nowhere'. Anyway, with
hdparm optimizations or without them processor time consumption remains
at a 70 - 90 % so, clearly, I haven't made any progress.
The only interface for cdrom drives that i've enabled in the kernel is
scsi (to be able to record and rip w/ cdrdao). I guess that the
inability to use dma is related to that because my ide hard disks seem
to be using it w/o problems (and obviously I'm not using scsi with
them). Nevertheless, I can't set up a multcount higher than 8, which is
really surprising because the ide chipset and the drives are quite new.
So I repeat my enquiry, Is all this a question configuration or of a
kernel upgrade? I've already tried the latter, but, as far as I could
appreciate, the current nvidia 'accelerated' drivers (1.0-4363) for my
geforce2 didn't work with the 2.5 kernel (more precisely 2.5.69) I'd
compiled. Once more, is this incompatibility a current issue of these
kernels? In case it were an configuration error I would certainly do
the upgrade because 2.5 kernel series seem to have many advantages, as
for example, the inclusion of the alsa sound drivers.
