I have tried this procedure but my Beaglebone Black (BBB) does not boot from the microSD, just from the on-board eMMC. I have limited experience with Linux-based systems and so i am sure I am doing, or not, something simple. I am using a rev A5C BBB with a 4GB FAT32 micrSD. Any pointers will be gratefully received.

I'm having the same issue as jgainsborough.
I formatted a 4GB SDHC as FAT32, extracted the zip to it, inserted into powered-off BBB, held down USER/BOOT applied power, and waited. Never saw any lights other than the power light. Have tried many times, holding down USER/BOOT for as long as 30 seconds.
Have tried with USB and with power supply. Same behavior. Board boots runs fine from internal memory.
The page neglects to mention that the partition on the SD must be marked active in order to be booted from when you hold down the USER/BOOT button.
You can mark an SD partition active by following: http://www.kozio.com/blog/how-do-i-make-an-sd-card-partition-active-under-windows-7
I had to hold down the S2 (USER/BOOT) button near the microSD card, while applying power to the board (by plugging in USB cable) in order to boot this firmware and extract the eMMC image. Pressing RESET while holding the S2 button did not work. After several seconds, I released the S2 button and then the LEDs started blinking. It seems the boot sequence doesn't proceed while S2 is being held down.
Edit: A further test shows that holding the S2 button for too long (15+ seconds) causes the board to turn off.
Note: I just formatted the card with FAT32 and copied the files to it. I did NOT mark the partition as 'active', but DID have to hold down the S2 button when applying power.
