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.

Newbie question: kernel image a dynamically linked binary?

Hello List,

I'm a newbie and coming from Linux background, and am trying to learn
FreeBSD now. The first thing I find a little confusing is that the
final FreeBSD kernel image is shown as a DYNAMICALLY LINKED binary:

$
$ pwd
/boot/kernel
$
$ file kernel
kernel: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD),
dynamically linked (uses shared libs), not stripped
$

How can the kernel image use shared libraries? And which ones does it
use, if any?

Also, I cannot find out the libraries the image uses using the
traditional ldd command:

$ ldd kernel
kernel:
kernel: signal 6
$

Can some please throw some light?

Thanks,

(Continue reading)

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

Hi,

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

It's a hack that is used so that the kernel linker is able to link in kernel

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