W jaki sposób można wyłączyć w kontrolerze SATA obsługiwanie UDMA na
jednym z kanałów ?
Mam podłączoną kartę CF PQI x120 na takim kontrolerze
http://allegro.pl/item993329556_ssd_na_sata_cf_microdysk.html
Karta zgłasza się jako obsługująca UDMA

W rzeczywistości jest to tania karta nie posiadająca kontrolera UDMA.
Wyłączenie w BIOS-ie trybu UDMA (zostawianie tylko MWDMA2) niczego nie
zmieniło, krenel pewnie ignoruje ustawienia w BIOSIE.

Pamiętam, że kiedyś trzeba było wygenerować initrd z modułem kontrolera IDE
(PATA)
ładowanym z odpowiednim parametrem wymuszającym wyłączenie UDMA.
Jak to wygląda teraz ?
Korzystam ze sterownika ata_piix ponieważ w trybie ahci nie udało mi się
podnieć systemu na karcie CF z
używanym adapterem.
Czy poleceniem sdparm można wyłączyć tryb UDMA na danym kanale ?
Z góry dziękuję za pomoc.
Krzysztof
