I have a Beaglebone Black industrial(BBBI), which I assume is very similar to the Beaglebone Black.

I wish to make the BBBI boot to microSD card by default, and I found this [guide](http://elinux.org/Beagleboard:Updating_The_Software#Image_For_Booting_From_microSD), which suggested to delete the `MLO` file from the boot partition. This has been mentioned in a few places based on Google, so I assume it is worth trying

With the intention of renaming the `MLO` file, I tried to locate the file using `$locate`, after booting without a microSD card, which presumably boots into Debain on the eMMC. This produces the following:

```
/opt/backup/uboot/MLO
/opt/source/pru-software-support-package/pru_cape/bin/MLO
/opt/source/pru-software-support-package/pru_cape/bin/MLO/beaglebone
/opt/source/pru-software-support-package/pru_cape/bin/MLO/beaglebone_black
/opt/source/pru-software-support-package/pru_cape/bin/MLO/beaglebone_black/MLO
/opt/source/pru-software-support-package/pru_cape/bin/MLO/beaglebone/MLO

```

I have double checked that `/boot` does not have `MLO`. Is anybody able to share where the MLO is, or did I missed something very obvious? 

Alternatively, is there an easier way to boot from the microSD card without pressing the S2 button?
