FreeBFreeBSD-12.3-RELEASE-amd64 Auto ZFS MBR BIOS Encrypt Disks and changing provider nodes

freebsd-questions:

I recently installed FreeBSD-12.3-RELEASE-amd64 onto a desktop x86 PC 
(Intel DQ67SW motherboard; UEFI disabled in the firmware):

When I boot, I see the prompt:

GELI Passphrase:

When I enter the GELI passphrase and press <Enter>, boot continues and 
the computer works.


When I add two SATA Host Bus Adapters (StarTech PEXSAT32) and four SATA 
drives (Seagate ST3000DM001), boot, enter the GELI passphrase and press 
<Enter>, boot continues and then displays another prompt:

Enter passphrase for ada4s1d


It appears that FreeBSD has assigned a different device node to the OS 
drive -- it was ada0 at installation, now it is ada4.


When I enter the passphrase and press <Enter>:

GEOM_ELI: Wrong key for ada4s1d.  Tries left: 2.
Enter passphrase for ada4s1d


The passphrase no longer works.  After two more failed attempts:

Mounting from zfs:f4_zroot/ROOT/default failed with error 2; retrying 
for 3 more seconds
Mounting from zfs:f4_zroot/ROOT/default failed with error 2.

Loader variables:
   vfs.root.mountfrom=zfs:f4_zroot/ROOT/default

Manual root filesystem specification:
   <fstype>:<device> [options]
       Mount <device> using filesystem <fstype>
       and with the specified (optional) option list.

     eg. ufs:/dev/da0s1a
         zfs:zroot/ROOT/default
         cd9660:/dev/cd0 ro
           (which is equivalent to: mount -t cd9660 -o ro /dev/cd0 /)
