Аппаратный RAID HPT370

Здравствуйте.

Помогите поднять аппаратный raid массив работающий на двух IDE-винтах по 80 гигов каждый. Режим должен быть mirror (raid1).

Итак, я включил поддержку raidа в BIOS, и собрал его как raid-1.
Далее загрузился, и собрал ядро с поддержкой драйвера (HPT370) в виде модуля (CONFIG_PATA_HPT37X=m), при загрузке он его распознает:

Насколько видно они определились как /dev/sdb и /dev/sdc диски. Теперь я хочу работать с ними как с одним диском. К сожалению, документации в google я не нашел, везде только software raid.

Об аппаратном я не нашел документации. Подскажите пожалуйста, что делать дальше, или хотя бы киньте ссылочку, где я могу посмотреть инфу.

В FreeBSD все решается обычным добавлением драйвера в ядро и получается что система видит два винта по отдельности, скажем da0 и da1 и появляется новое устройство ar0 которое и работает как аппаратный raid. Я так подозреваю, что в Gentoo должно быть что-то похожее.
