UDMA 66 не работает-help

а по какой технологии - CMD или PROMISE ....?

www.via.com.tw -> в поиске Linux -> там есть описание решения проблемы с ДМА больше 33-х
А у меня проблема другая - ДМА вообще не работает :(
У меня: ═AMD AthlonXP 1600+, m/b EPOX 8KHA+ (VIA KT266A), HDD@Primary Master IBM IC35L040AVER07-0 (40 Gb, 7200), CD@Primary Slave MATSHITA CR-585, ATAPI CD/DVD-ROM drive,
Red Hat 7.2 (Russian) (first installation)
The problem is: UDMA/DMA does not working at all.
Can you say anything about it?
