Re: new hdd numeration after mainboard change
Thank you very much, of course it was the AHCI configuration in the BIOS, luckily i can now switch between AHCI and compatibility mode when using Windows(otherwise it will result in a bluescreen) ;-) Best regards, Marco Josh Paetzel wrote: Jeremy Chadwick wrote: On Mon, Oct 13, 2008 at 07:12:20PM +0200, [EMAIL PROTECTED] wrote: i run FreeBSD 7.1-PRERELEASE i had a change of the mainboard of my lenovo notebook t60. after reboot the harddisk which was before recognized as ad0 is now ad4. i cannot find any other devices, no ad0/ad1/ad2 in /dev. even in the dmesg only ad4 The T60 is a laptop.

It's not really an issue. Very likely your computer has toggled some BIOS settings. The T60 series has the ability to run the SATA ports in two modes: AHCI, or Enhanced/Compatible. Chances are before the motherboard swap, yours was running in the opposite mode that it is now. I would highly recommend using the AHCI mode. It works quite well with FreeBSD under Intel controllers. Turn AHCI on (if it's not already), and do not mess with it. I can verify as a T60 owner, if you toggle the BIOS between AHCI and Compatability the hard drive will show up as either ad4 or ad0. It works fine in either mode with FreeBSD. Unless you are running another OS that doesn't have SATA support there's really no reason to use compatibility mode ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
