 Low priority, this only hinders a demo by limiting laptops available, and
 only affects B1.

 Diagnosis: game-key-mask is set wrongly on B1 Q2C26 or B1 is no longer
 supported.

 Problem: activation fails, lock icon appears.  Documented workaround did
 not work, apparently because X and O keys not recognised by Q2C26 on B1,
 the message "Release the game key to continue" does not appear.

 The possibility of electrostatic discharge lockup was tested for by
 repeating the problem on another B1, and by leaving a unit unpowered for
 several minutes per the usual process.

 Template questions per http://wiki.laptop.org/go/Autoreinstallation_image

 What version of the software you were upgrading from; 406.15 Q2C18

 What version you were upgrading to; 573 Q2C26 olpc-auto.zip 2007-09-13
 21:09Z

 What type of machine you have (b1, b2-1, b2-2, b3, b4, etc); problem
 happened on two B1 units, but not on the B2 or B4 units.

 What type of installation media you were using (USB flash key, SD
 card, something else?); 1Gb USB 2.0 flash key 1015808 blocks.

 How your installation media was formatted (FAT16, FAT32, ext2/3, etc) and
 partitioned (no partition, one partition, etc); FAT16, one partition,
 using the sequence included below.

 Did you follow the instructions in Step K (above) carefully for an
 unactivated machine?  Yes.

 Did you see the following text under "possible problems": "If the USB disk
 is not partitioned, builds before 552 will fail to activate."?  Yes.

 {{{
 # erase partition table
 dd if=/dev/zero bs=512 count=1000 of=/dev/sdc
 partprobe /dev/sdc

 # create partition table
 parted /dev/sdc mklabel msdos
 parted -- /dev/sdc mkpart primary fat16 0 -1s
 parted /dev/sdc print

 # create filesystem
 mkdosfs /dev/sdc1

 # create files
 mount /dev/sdc1 /mnt
 cd /mnt
 unzip /olpc/olpc-auto.zip
 cp /olpc/os573.{img,crc} boot/
 cd
 sync
 umount /mnt
 }}}

 Additional information: the OFW ok prompt can be obtained by pressing Esc
 key during startup.  The version string shows Q2C26.  watch-battery shows
 "AC:on  PCB: 30C No battery" no matter what battery is inserted.  The
 battery charge LED remains orange while a battery is in place, until the
 battery charges.

 On B1, when powered up with or without the X and O keys on the game keypad
 depressed, game-key-mask is 100.  Yet with the same keys down, game-key@
 yields 102.

 On B2 and B4, when powered up with X and O keys down, game-key-mask is
 102.  game-key@ matches.
