It's _not_ in-band, though.  It's in this thing called the "partition

In the case of the i386 port, though, since by convention, b, c, and d
are reserved partitions, this leaves only five partitions available.

...speaking of which, I remember distinctly something really nice
about OSx on the Pyramid 9800 series:  the partition tables, though
still hardwired, had 16, rather than 8 partitions per disk.  I know
various PROMware, whose manufacturers (like Sun) shall go nameless, make
various assumptions along the lines that "All disks have 8 partitions",
but this is a topic that has been discussed but not fully addressed.
