Re: ide controller recommendation



Chris -
Thank you for your advice. I should ve mentioned that the original IDE
controllers(Intel 82371AB IDE) which have failed where built into
motherboard. Do you think there is something else worth trying before
submitting a report and buying  ide controller card?

Thanks,
Mikhail.
