'-d1c1U1' should be with the 'U' as a lower case letter (u).
Sorry about that. A huge difference indeed. U unregisters the interface.
As a general rule, don't just run stuff from a mailing list without reading documentation first. :-)
So I am finding out :-) .
However, altering the parameter to '-d1c1u1' produced the right result
and now I have DMA set on the DVD/CD reader. Thanks for that.
If it works, you can put it in /etc/init.d/boot.local(This is where I put the above statement and, as I said, it works.
For those who will try this to get their DMAs set, you have to reboot
for the above parameters to work.)
Not quite proper, but it does the job and you don't have to worry
The proper way would be to put in /etc/sysconfig/ide
but if that doesn't work, the hdparm -c1d1u1 it's even better: enables 32 bit access and unmask irq.
Well, using /etc/sysconfig/ide does NOT work - see my repsonse to Carlos.
Only way it works is to use the /etc/init.d/boot.local way.
But there is a question: the above 'fix' is for /dev/hdb. How does one
go about also doing it for /dev/hdd? Does one simply add another line in
boot.local for hdd?
Add an identical line for hdd.
Thanks for this. I have now did just that in boot.local.
Ignorance can be corrected. Stupidity is permanent.
