I'm trying to install FreeBSD as part of a dual boot config on a hard

FreeBSD. My problem comes once I "commit" to the installation of
FreeBSD. I get the following message, after which installation aborts:
"Unable to find device node for /dev/ad4s2b in /dev! The creation of
filesystems will be aborted." What am I doing wrong?

Are you trying to install FreeBSD in an extended partition? The
/dev/ad*4*s2b makes me think so ...

/dev/ad4 is probably his first SATA drive, the integer
following "s" is the slice number (partition in the magical
windows world) and if greater than 4 indicates an extended
slice.

I thought /dev/ad4s2b meant the 5th disk (since its ad4; ad0-ad3 being 1st to 4th disks), 2nd slice (s2), and second partition in that slice (b). Do SATA drives too come up as "ad" devices? I don't have experience with SATA drives, so don't know ... I know my IDE drives come up as "ad" and so would assume SATA will come up with a different name.

Rakhesh is correct.

SATA / PATA drives show up under ad[m]s[n][l], where m is the disk number (zero based), n is the slice, aka partition number in the non-BSD (/Solaris?) world, number (zero based), and l is the respective letter for the partition (it can vary depending on the purpose, a being root, b slice, c all of the disk, [d-j?], other values / relevances. SCSI / SAS is almost exactly the same. The only difference is 'ad' is replace with 'da'.
