Hola a todos. Les pido una mano con el disco duro, no sé por qué me dice |
| 2 |
que no tiene el DMA habilitado, sin embargo si hago "hdparm -I /dev/hda", |
| 3 |
parece que estuviera habilitado. |
| 4 |
Preguntas: |
| 5 |
-- Está realmente habilitado? |
| 6 |
-- Cuál es la correcta configuración? me refiero a los múltiples DMAs y |
| 7 |
PIOs... |
| 8 |
-- Cómo hago para que cuando resetee no se pierda la configuración? |
| 9 |

Les mando los datos que me da la PC. Tiene un kernel 2.6.5-gentoo-r1 sobre |
| 11 |
una AMD Athlon XP 2000+. Les agradezco la ayuda, mucha idea de esto no tengo! |

Gracias!!! Facundo |
