Comment 3 for bug 577120

I am experiencing the same problems with Zotac ION F.
When I boot XBMC Live which uses GRUB2 from USB-Stick it takes roughly 1 min after the GRUB Menu to get to the XBMC logo, where the "real" boot is happening.
With "set debug=all" in grub.cfg you can clearly see that nothing happens within this 1 min blank screen.
I already unplugged my hard drive and optical drive but unfortunately with the same result.

There is no issue when I use legacy GRUB instead.

The Zotac also uses AMI BIOS.

This delay is really annoying and decreases the WAF of my HTPC tremendously.
I would highly welcome any fix for it!
