Tu lascialo sempre attivo che tanto il problema non riguarda le mini-itx

attiva attiva, dvd a udma 4 e hd a 6

OK!
Purtroppo pero`, dopo averlo umpostato [UDMA 133 (70) per l'HDD e UDMA 66 (68) per il DVD], se spengo e riaccendo la SAM, perdo le impostazioni e ritorno al PIO mode.
Non riesco a salvare le impostazioni.
Che dipenda dalla versione di U-BOOT? (Non ho neanch'ora caricato l'ultima).
Parto cosi`:
HARD DISK da SHELL idetool -u sii3114ide.device 0

Imposto cosi':
HARD DISK da SHELL idetool -x sii3114ide.device 0 70
Unit 0 : transfer mode 70 returned 0
DVD RECORDER da SHELL idetool -x sii3114ide.device 3 68
Unit 3 : transfer mode 68 returned 0
Fino a quando la SAM resta accesa le periferiche restano impostate con il DMA scelto:
HARD DISK da SHELL idetool -u sii3114ide.device 0
-------------------Unit 0 information------------------------
Flags : $00000185 - present, supports DMA, ATA, supports cache flush, interrupts used,

Poi pero` spegnendo e riaccendendo, perdo di nuovo tutte le impostazioni.
