Greetings Mark!

I put linux-kernel back, in case someone else has ideas.

I will check it (the card is at home and I am in the office) and let you know.

Well, if it, as you say, works in "ata compatibility mode"
and there is no specific driver (in Linux) then it is not
broken but (currently, under Linux) just _very_ slow,
until someone writes a specific driver for that chipset.

But I am not interested in subtle semantics of "slow" vs "broken".
All I want is for my data to arrive at the disk (and come back, sometimes)
a bit faster! :)

Kind regards

drivers/ide/pci/siimage.c
Did you forget to compile it? :-)

Yes, you are right! :)

Thank you! If I am silent that means I went home, compiled the driver
and my card now works fine at 20M/s. Otherwise I will let you (and everyone)
know.

Kind regards

Just to confirm:

a) the reason I didn't notice siimage native driver is because I was using 
2.4.20 and it's not there.

b) with 2.4.22 it works! And I get 54M/s on one drive and 38M/s on 
another, which is a lot faster than my onboard IDE controller.

Now, let's hope that ide-scsi subsystem (and thus my DVD writer) still 
work with 2.4.22. I heard some problems about ide-scsi on 2.4.22...

Kind regards
