Ce qui est bizarre c'est qu'au boot il positionne mon disque (hda) en
mode PIO alors que mon lecteur de dvd et mon graveur sont bien en DMA:
VP_IDE: IDE controller at PCI slot 00:07.1
VP_IDE: chipset revision 6
VP_IDE: not 100%% native mode: will probe irqs later
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1
ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0xd008-0xd00f, BIOS settings: hdc:DMA, hdd:DMA
hda: Maxtor 6Y120P0, ATA DISK drive
blk: queue e8825500, I/O limit 4095Mb (mask 0xffffffff)
hdc: PLEXTOR DVDR PX-708A, ATAPI CD/DVD-ROM drive
hdd: HITACHI DVD-ROM GD-7500, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
[...]
hda: attached ide-disk driver.
