Date: Tue, 16 Jan 2001 10:49:05 -0500 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2448.0) Content-Type: text/plain Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I have one issue which requires fix from the linux kernel. Initially i put a SCSI controller and install the OS on the drive connected to it. After installing the OS (on sda), the customer puts another SCSI controller. The BIOS for the first controller has BIOS enabled and for the second controller does not have the BIOS enabled. The linux loads the driver for the second controller first and assigns sda to it first , and the actual boot drive gets some sdX device node. >>From the lilo prompt we can override it with root=/dev/sdX to boot to the correct drive and controller, but for a end -user using these cards, this is no fun. Can the linux kernel be changed in such a way that kernel will look for the actual boot drive and re-order the drives so that mounting can go on in the right order. we need some kind of signature being written in the drive, which the kernel will use for determining the boot drive and later re-order drives, if required. Is someone handling this already?
