In-Reply-To: <3A2BF6A2.1BD792BA@windsormachine.com> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi everybody Tried turning PIO and/or PCI burst in BIOS off - no use:-( The former one only slows the disk a lot. Andre, I've sent you an email with the entire story, forgot to mention there - a few people did draw my attention to 'PIIX: neither IDE port enabled (BIOS)' and neighbouring messages in dmesg, but nobody was able to explain what particularly is going on (BIOS does recognise HD and CD-ROM fine) and how to fix it. Re: PCI clock... Something somewhere (can't find now) made me think that my MB is setting the PCI clock synchronously with the CPU clock, i.e. it is 25MHz in my case... Any ideas where I could see it?:-) In BIOS 'Latency Timer (PCI Clocks)' is shown as 66MHz, does it mean that my PCI bus clock IS @ 66/2=33MHz? > Guennadi: I don't suppose you can get your hands on a different size/brand drive > long enough to plug it in, and see if it allows DMA? I'll try... Not sure though... Thanks Guennadi ___ Dr. Guennadi V.
