Копался я вчера часа 3... Много узнал... Но так и не смог существенно поднятьскорость чтения с винтов... Удалось в общем случае на ~5-7 мб/с чтолько поднять для hda и hdc...
Вобщем вот все что догадался притащить с собой...
Помогите...

Мать — tusl-2c. Оперативки 512 метров, камешек — целерон 800...
Драйвер — piix, вкомпиленный в ядро. Копался я в его сорцах — он понимает udma 4.
ps а с CD то как быть?
