Hi all, I've set auto boot time on my G 100 to 3 seconds, and now I got problem to change it. I'm wondering if anybody could help me with this problem.

Thanks

Does that mean you can't get back into the loader program ?
If so, start the GRexLoader program. Unplug the G100, plug it back in, and click on the Find Gecko a couple of times until you get an IP address then click on the launch Firmware Loader button immediately (you only have 3 seconds).
