AHCI Driver on ICH7 (27c08086) Chipset

Hi Everyone,

I have a new motherboard with an ICH7 chipset (G41) and the ata driver
recognizes it as ATA_I82801GB_S1 (PCI ID 27c08086), but this card does
not seem to work with the AHCI. Can anyone point me to why this is the
case? I really need NCQ working for this machine.

Thanks,

Most of ICH7 chipsets (especially on cheap boards) do not support AHCI
mode. Only ICH7R and ICH7M do, if BIOS is so kind to enable it.

In short: ICH7R and ICH7M both have AHCI support but ICH7 does not.

Re: Newbie question: kernel image a dynamically linked binary?

Hi,

Please don't crosspost to many lists.  This topic is probably
suitable for hackers <at>  but not for the other lists.

To clarify, I would hack this into an /etc rc script, not in the script
embedded into the uzip image.

So, how is it going?  Any benchmarks yet?  I'm curious
if the new gcc version will really make a significant
difference.

Best regards
