Yes, Thank you. I had seen that before, but couldn't remember where.

Update on my MMC cards. I was able to get them to show back up with a remove the battery reset. For some reason shutting down with the button didn't get the cards to re-mount, and when I tried to remount them manually I got an error about some file not being found.

So I continued with the dual boot process, and finished the HowTo. I can get Marvin to boot from flash just fine, but when I boot from the MMC, he will get as far as the gas gauge going across the screen and hang there. In order to get him to reboot so I can select flash again, I have to take out his battery. I ran a chkdisk on the MMC like the Blog says, and it reported and corrected some errors, but still no joy in Muddville.
