I want to apply a patch to enable AHCI on my Dell inspiron.
I apply quirk-ich-force-ahci.patch patch to /usr/src/linux-source-184.108.40.206/drivers/pci/quirks.c
But now what to do next?
Well, do as you want... But why the hell do you want to patch the kernel to add something which is already included ? As far as I know, AHCI is supported out of the box since kernel 2.6.19...
Sorry for not explain in details.
It was not about AHCI support in kernel.
Some Dell notebooks have ICH7-M chipset and SATA HDD but is working on compatible (emulated) mode and there is no option in bios to switch to real sata.
Since I can't post links outside I can't point you to patch without breaking forum rules,I only talk about this and my mistake I didn't provide detailed info.
This patch will force enable sata on some chipsets,including ICH7-M
Anyway I already did it,I recompiled kernel and is working.
Since I don't know much maybe was working just if I recompile some modules,that was I asking,recompile full or just some patched modules?
If someone else is interested about this patch search on google for "Intel SATA chipsets and AHCI"
