I have remote machine with console access almost impossible (very > hard for me). In most cases order of adaX devices should match order of ad devices, so first adX will become ada0, second - ada1, etc. The only exception there should be devices on ATA channels in legacy/ISA emulation mode: ata0 (ad0/ad1) and ata1 (ad2/ad3). Old ATA always allocated these devices first, but new ATA will allocate them as any other in order of their channels registration. That order you can see in dmesg. -- Alexander Motin
