How I cracked the Cr-48 Easter Egg

How I cracked the Cr-48 Easter Egg

I found the easter egg developer Bill Richardson teased. There’s a blue screen of death hidden within the bios!

Here’s how I found it. First, I located Mr. Richardson’s LinkedIn profile. From there, I discovered:
I’m working on Chrome OS, specifically verified boot, BIOS, autoupdate, and other low-level things.
I, also, discovered that Bill Richardson spent a considerable amount of time with Sun Microsystems as a Senior Software Engineer. Among his projects was Integrated Lights Out Management (ILOM). I performed a google search for “ILOM easter eggs” and found this site. The command xyzzy caught my attention.

It was already hinted that this easter egg was specific to the Cr-48 and not Chrome OS in general, so I focused on the differences between the Cr-48 and commercial Chrome OS devices.

The fundamental difference is that the Cr-48 has a developer mode switch. I flipped this switch and typed xyzzy during the boot procedure and up popped the hilarious BSOD with a number of references and a hidden message. Here’s my post on the Chrome Notebook Pilot Google Group revealing my discovery. Hidden message after the jump!

Within the blue screen of death was a hexadecimal message.
Converting this to ASCII characters reveals the following message:
