Hi,

I hoped that you had a USB attachable optical drive in reach for development.

After copying the ISO image to the base device (/dev/da0 rather than
/dev/da0s1), it now carries the isohybrid MBR which marks a single DOS
partition and leaves the rest of the disk unclaimed. A partition editor
should be able to push the end of the partition to the next 1 MiB boundary,
without altering the partition content.

But as said, it is unlikely that this misalignement of the partition end
is the cause. The observable state of ISOLINUX rather points to a problem
between hardware, firmware, and the SYSLINUX programs. 


Have a nice day :)

Thomas
