single SATA disk and yet identified as 'ad4'
Hi all: The system has just one SATA disk and yet bootloader process identified it as 'ad4'. Ideally, it should be ad1.

Re: single SATA disk and yet identified as 'ad4'
You may want to become familiar with: # # The following options are valid on the ATA driver: # # ATA_STATIC_ID:controller numbering is static ie depends on location # else the device numbers are dynamically allocated. options ATA_STATIC_ID Long time ago FreeBSD people decided that it's very annoying when you plug ata CD or another HDD and then your ad1 (which is ad4) becomes ad2, and makes your OS un- bootable without manual intervention. Today we have geom labels, but still ATA_STATIC_ID is something I really miss on every linux .. P.S. -current removed.

FreeBSD reserves numbers for devices that aren't currently connected, so that if you connect them later your existing devices don't need to be renumbered. It does this if you have 'options ATA_STATIC_ID' in your kernel config (which is the default.) Otherwise all PATA/SATA disks installed will numbered from ad0 upwards without any gaps. The drawback of that is that without the static numbering the disk devices can (and often will) be renumbered if you add or remove a disk, which often is not desirable. Your BIOS is reporting two IDE interfaces, each of which could have a master and slave disk drive, so ad0-3 are reserved for those four drives, meaning SATA starts at ad4.

Re: single SATA disk and yet identified as 'ad4'
By default, ATA disks are assigned numbers based on the ATA controller they are on, and whether they are primary or secondary on the controller. For example, the primary disk on the first controller would be ad0, the secondary disk on the first controller would be ad1, the primary disk on the second controller would be ad2, etc. This is the ATA_STATIC_ID kernel option. I expect that there are two ATA controllers before the one your disk is on. You may confirm this by running atacontrol list. -Boris Saifi Khan wrote: Hi all: The system has just one SATA disk and yet bootloader process identified it as 'ad4'. Ideally, it should be ad1.
