Próbuję zoptymalizować dysk twardy poprzez włączenie DMA, jednak nie mogę tego zrobić:
Kod: Zaznacz cały
hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 2112 MB in 2.00 seconds = 1056.13 MB/sec
Timing buffered disk reads: 192 MB in 3.00 seconds = 64.00 MB/sec
Kod: Zaznacz cały
hdparm -d1 -c1 /dev/sda
/dev/sda:
setting 32-bit IO_support flag to 1
HDIO_SET_32BIT [B]failed:[/B] Invalid argument
setting using_dma to 1 (on)

IO_support = 0 (default)

Próbowałem także na:
2.4.21 i z live cd Knoppiksa 2.6.36.1
Na wszystkich dzieje się to samo. Oczywiście w biosie mam ustawione:
