Hello I have the mainboard G41M-E43 from MSI. The Sata controller comes from the ICH7 chip, with the speed of UDMA 133. Here is identifiers by the Pci bus: "lspci -nn | grep SATA 00:1f.2 IDE interface [0101]: Intel Corporation NM10/ICH7 Family SATA Controller [IDE mode] [8086:27c0] (rev 01)" So, I have connected Sata drives on it and this is no at the full speed. It was fine before, because I don't need speed into this computer. Today, I'm looking for performance, and I can't change the speed to SERIAL ATA II: - I have no option into the latest bios of the motherboard to specify AHCI mode - I have tried "setpci -d 8086:27c0 90.b=40" or "setpci -s 00:1f.2 90.b=40" in the grub configuration with no effect . I'm looking for help. I've find your email because I have read the file linux-source-3.2.0/drivers/ata/ahci.c . Is it a new device for this driver ? Have you a workaround like 'setpci ...' to change the speed of the Sata controller ? Thanks a lot!
