My Dell Dimension, with a Pentium II and purchased in
January of 1999, has a BIOS that allows setting the
boot sequence.

My Dell's BIOS will boot from the partition designated
in the boot.ini file in the Active partition of the 1st drive
in the BIOS' boot sequence. I think in the vanilla case,
that boils down to what you said, but what you said
does not include the case involving drives on different
IDE channels - where the drive jumpered Slave may
be the "boot" drive if its channel happens to be higher
in the BIOS' boot sequence.

The thread of this discussion implied much more importance
to the jumper settings or cable positions than is the case.
Any functional result from "Master" or "Slave" designation is
totally overridden by the boot sequence in the BIOS - which
has been accessible AFAIK in all Dell PCs for at least 5 years.

But let us be clear that "correctly" means merely
"to differentiate them for the channel" as that is all
that the Master/Slave roles imply to the user. Which
partition on which hard drive gets loaded is determined
by the boot.ini file on the Active partition of the 1st device
in the BIOS' boot sequence. All those parameters are
available to the user to set. For example, the 3rd partition
on a drive jumpered "Slave" on another channel can
provide the booted system if the settings so indicate.
After reading "the drive that is Master is booted" so often,
too many people start to believe it. In reality, that is true
only in the very very vanilla case.
