diff --git a/init/send-boot-mode.conf b/init/send-boot-mode.conf
new file mode 100644
(snip)

So, I remove send-boot-mode.conf from USB Stick and retried, then it worked.

I do not know why problems will arise if this file is present.

The same problem is occurring in NEC PC-BL300TA6B.
Both CPUs are Atom N280 and the chipset is 945GSE.

Please try x86-generic with Atom N280.
