There should be a copy of zImage in the boot directory of the root
filesystem and you can verify this by manual inspection. Normally you
don't need to put a copy in the dos boot partition.
When you attempt to use the sd-card in the BBB make sure you hold down
the USER/BOOT button for about half a second when applying power to the
board. This will force the processor to load the MLO/u-boot.img files
from the SD-card, which by default will attempt to load zImage from the
root filesystem.
Also make sure the dos boot partition has the boot flag set. gnome disk
utility is a good tool for creating and checking the partitions on the
sd-card.
Older versions of MLO/u-boot.img will attempt to load uImage from the
root filesystem instead of zImage. This can cause problems if you don't
hold the USER/BOOT button down during first power-up boot, as the
processor will then attempt to load MLO/u-boot.img from eMMC (which may
attempt to load uImage).
A number of recent threads in the beagleboard.org/Community/Forums
mailing list discuss the BBB boot process in more detail.

All,
Thanks very much for all the answers to my previous questions. I'm
trying to install the Angstrom image on the BeagleBoard Black. I could
not locate the official instructions, and using instead the instructions
at http://derekmolloy.ie/building-angstrom-for-beaglebone-from-source/
does not work with the latest version of the code.
So first question: where are the official install instructions located?
You may not want to read the rest until I adjust my SD card per official
instructions J. But here is my

I've formatted my 2G SD card with mkcard.txt from
http://downloads.angstrom-distribution.org/demo/beaglebone/, copied
u-boot.img and MLO on the 1st (vfat) partition of the SD card, and
unpacked Cloud9-IDE-beaglebone.tar.gz on the 2nd (linux ext) partition.
Yet I can't figure out where the kernel image zImage is supposed to go.
And without the kernel on the SD card, it won't boot.
Thanks,
Andrei
