Boot your system e.g. with SystemRescueCD then do lspci -k this shows you which module is in use. Then build your own kernel with this module. Helmut.

I'm surprised that the newer mobo (G41) dropped support for AHCI which the older mobo (G33) had, but it shouldn't make much difference I'm planning to build an upto-date machine later in the year. So I'm now able to operate normally in the 2007 machine, but it still has a problem with Eth0, which hopefully wb easier to fix: this is being sent from the 2003 machine, which chugs along adequately. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

That's Intel for you. Similar situation with their CPUs. I always feel depressed if I have to purchase an Intel CPU. Feature support (e.g. VT-x) are not guaranteed to exist, even when the CPU is a new one. Rgds,
[gentoo-user] changed motherboard, no AHCI
My motherboard went on the blink earlier this week. I've now successfully installed a new one, but now can't get the kernel to find the SATA hard disk (803 etc). The problem seems to be that the kernel has AHCI enabled, which was necessary for the old mobo, but the new one's BIOS doesn't have an option to select AHCI. The Ubuntu + Mandriva partitions start properly, as does System Rescue, so the problem has to be in the Gentoo kernel configuration. (1) Can I simply drop AHCI from the kernel or do I need to do something else ? (2) Can I recompile the kernel without going thro' a partial re-install or do I need to do a change-root etc to get it to work ? Can anyone advise ? -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

Boot into you other distro, Mandrive or Ubuntu should work fine. You just need the chroot command. Mount the Gentoo partitions just like you would during the install. Just mount them tho, NO file system or disk formatting stuff. ;-) Once mounted, just follow the chroot instructions just like in the install. These are the current ones: cd / mount -t proc proc /mnt/gentoo/proc mount --rbind /dev /mnt/gentoo/dev cp -L /etc/resolv.conf /mnt/gentoo/etc/ chroot /mnt/gentoo /bin/bash env-update source /etc/profile Once you are in there, cd to /usr/src/linux and make the needed changes, recompile, copy the new kernel over, edit grub.conf if needed and then reverse things so you can reboot. Don't forget to run env-update just before exiting. Also, I sometimes have trouble unmounting some partitions. Just unmount all you can before you reboot. I usually can't get the dev and root ones unmounted. It appears that something gets busy and can't be stopped. Your mileage may vary tho. You should be able to reboot Gentoo and hopefully the new kernel will work. Also, check into options you can add to the grub line when booting. Remember, you can edit grub and change the boot process. I'm assuming you are using grub instead of lilo. Hope that helps. Dale :-) :-) -- I am only responsible for what I said ...

If your mobo has vista/win7 certification, it does support AHCI. Or is so horribly broken you should RMA ASAP. It's an Asus P5G41T-M LX the manual says : This motherboard supports Windows Vista/XP/7 OS. The previous mobo (Asus P5K-VM) has a menu Main - IDE Configuration - Configure SATA as [IDE] with an option 'AHCI', which was enabled the kernel booted properly; its manual says If you want to use the SATA drives as parallel ATA physical storage, keep the default setting [IDE], but that caused the same problem that the kernel couldn't find the drive; when I configured it as [AHCI], everything worked (since 2007). The new manual has a menu Main - Storage Configuration - ATA/IDE configuration [Enhanced] which corresponds to a menu 'SATA configuration' in the old manual [Enhanced] opens another item 'Enhanced mode support on S-ATA', which allows you to set Serial/Parallel/Both for ATA. Since Ubuntu, Mandriva System Rescue boot without any problem SR does find my LVM partitions can mount them properly, there must be settings which allow the kernel to find the HD with this mobo. I will look them up compare them all later today, but any further advice is very welcome.
