Syslinux - Aug 2010 - gpt and extlinux how to get it bootable?

Hi
I just tried to implement gpt extlinux booting in my archboot project.
extlinux installs fine but i'm not able to boot the hd afterwards.
Setting partition to boot on in parted doesn't seem to have an effect in GPT
mode.
Is there any way to get it booting, i haven't found any docu about it.

Thanks in advance
greetings

Hi Tobias,

Bit 2 of the attributes for the parition in question need to be set.

I made patches to sgisk (part of sgisk) and submitted them to the
author about a month ago, but I've gotten no response.

Here is my latest patch.
http://bogen.teegra.net/gdisk-0.6.9-sgdisk-attributes.das-r0.patch

# make hda1 gpt partition 1 legacy bios bootable
sgdisk /dev/hda --attributes=1:set:2

# show attribute bits that are enabled for hda1 gpt partition 1
sgdisk /dev/hda --attributes=1:show

# disable gpt partition 1 legacy bios booting
sgdisk /dev/hda --attributes=1:clear:2

Sincerely,
Dwight Schauer

I posted a message on parted's mailing list about this item... Still no
answer from them.
