# Setting up the Haiku SD card
|
|
|
|
The BeagleBone Black supports booting from an microSD card while the boot switch is pressed at power on. A MBR file system layout is normally used as seen below. Partition 1 is all that is required to boot an OS.
|
|
|
|
* partition 1 -- FAT32, bootable flag, type 'c'
|
|
* partition 2 -- BeFS, Haiku filesystem, type 'eb'
|
|
|
