Re: DMA !NOT ONLY! for triton again...

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?

I'll try... Not sure though...

Thanks
