Thanks Jerry. Yes, it will. Open Firmware is trying to open the file u:\boot\olpc.fth ... which is a file specification without a partition number, therefore it will choose either the first partition with a bootable flag, or if there are no such partitions it will use the first partition. So my earlier advice to remove the bootable flag was incomplete; I should have suggested moving the bootable flag away from the NTFS partition onto the Linux partition. If the XO is secured, it should proceed normally. In the absence of the fix to the bootable flag on the partition, an unsecured XO can use a special configuration setting as a semi-permanent workaround: ok add-tag BD int:\boot\olpc.fth This directs the unsecured boot process to begin with the internal storage, ignoring any external USB device or SD card. It does not affect secured boot, so the four-finger install method will still work. #12678 updated. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] 1TB drive of quality open content on XO/XS--won't boot
Hi James I'm using OpenFirmware Q7B26 EC Firmware 0.4.03 I have tried turning the boot flag off on the NTFS partition, but it still dumps me to the OpenFirmware ok prompt. I can reproduce the problem by formatting a USB stick to NTFS and trying to boot with it plugged in. So it is reacting badly to the mere presence of NTFS on USB media. -braddock On 05/12/2013 03:40 PM, James Cameron wrote: On Sat, May 11, 2013 at 03:44:18PM -0400, Holt wrote: Is there a way to boot a large USB hard drive attached to an XO?

It mounts correctly when the XO is booted, but if it is connected when the XO is powered on or rebooted, the XO drops to a firmware OK prompt.
