Linux not adhering to BIOS Drive boot 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?
It should be possible to read the BIOS setting for this option and behave accordingly. Please give full details of how to read and interpret the information stored in the CMOS for all versions of AMI BIOS, and I'll take a look at this.
To mount the right partitions , refer to the by the volume label or UUID.
( read the mount and fstab man pages for more info )
This work after the root-fs is already mounted.
Currently ( AFAIK ) the root-fs can be specified only as a major:minor pair ( and maybe also as a "/dev/hdxx" string )
Once I wrote a patch that allows specifying the root-fs by UUID or volume label. It is available at
http://linux-patches.rock-projects.com/v2.2-f/uuid.html
It is for 2.2.x kernel , since nobody seems to be interested in it.
As for the "device nodes are assigned to disk devices almost randomly" problem : I complained about this years ago , but nothing happened.
If someone knows a way to reliably find a certain partition , regardless of the (non)existence and position of other partitions and disks in the system , short of scanning the contents of all available
partitions , please tell me.
Party on !
