Bug#785241: i386 installer works, but amd64 did not

[Andrew Buckeridge - Private <andrewb@zagam.net>]

I have an Acer C720P.

When I tried the amd64 installer via USB and it just rebooted the BIOS.
I was able to run the i386 installer, pull amd64 kernel image and boot
it from the built in flash drive. The johnlewis.ie FAQs say try another
distro or mem=some_value. The i386 Debian userland is now running fine.

I had installed John Lewis' option:

> 1. Modify my Chromebook's ROM to run SeaBIOS exclusively
>    (and get rid of the scary screen).

I used debian-8.1.0-amd64-i386-netinst.iso installer from HD media.
The mbr-syslinux HD media image I made had both the amd64 and i386
versions of vmlinuz and initrd.gz in an MeS-DoS volume. I renamed the
i386 versions vmlinuz32 initrd32.gz. I booted those looked for the ISO
and it worked.

Had SeaBIOS-mbr-syslinux and something went wrong with amd64 USB boot.

I also tried flashing the amd64 boot.img.gz to whole USB device and it
also did not work.
