The B1 prototypes are complete systems, externally appearing very similar to production XO-1s ([[XO_CL1A|CL1A]]). OLPC should receive a couple hundred of these in August, 2009.
The B1 prototypes are just motherboards. OLPC received twenty of these on August 18, 2009, direct from the assembly line.

===Firmware===

XO-1.5 use Q3xxx firmware releases. These will not work on an XO-1.

B1 motherboards require a release equal to or later than Q3A08f. Download it from Mitch's home directory on dev.

Check the [[XO 1.5 EC dev changelog]] for information about the latest EC firmware (integrated into the above OFW releases).

This may be installed by downloading and placing on a USB stick, then:
# Ensure that you have both a somewhat charged battery and a DC power source
# Boot the laptop, pressing the escape key ('X' in upper left hand corner of keyboard) within a few seconds after boot to enter [[Open Firmware]].
# Insert the USB stick containing the new firmware
# Type:
flash u:\q3a08f.rom
