I seem to recall using the boot options “ide0=noprobe ide1=noprobe” on CentOS 4 and CentOS5 to prevent the SATA controller from being used as a legacy (lower performance) IDE controller.

Subject: Intel Mobile Express Chipset SATA AHCI Controller Hello all,
I'm in the process of trying to setup a Lenovo Ideapad U410 with Fedora 17. The system keeps putting the SATA drive into UDMA/100. Apparently the system has an Intel Mobile Express Chipset SATA AHCI controller. I have found next to nothing detailing Linux support for this controller. Does anyone have experience with this?
I've done the normal steps as far as checking to make sure the BIOS is set to AHCI and has been since I installed. When the system first boots I get messages such as "ata2.00: failed to enable AA(error_mask=0x1)" a couple times as it boots up. Probably going to open a bug report if I can't find anything else, but I'm not sure if this is a bug or just unsupported hardware. Any pointers in the right direction on handling this would be appreciated.
Thanks
Lucas |
