Senthuran, I don't believe that is possible.

If there is a way to do that, then I am not aware of it. I've tried to think of how you may do something like that. I've checked a list of BIOS interrupts, but there is no interrupt that you could use to modify boot settings. Your only hope is finding a good documentation of your BIOS and looking through the different interrupts it has for something relating to boot sequence or boot settings. If you can find something, I'll try to help you out.

Good luck.

I will look into it when I will have some time. You're lucky one of my older test machines is using the Award BIOS so I can test on that. For now I have to find some free time to dig up some documentation on it. Let me know if you can find something before I do.

Hey, senthuran, I found something that you may be able to use. I'm not sure if it has the boot sequence changing capability, but it's worth a try. If not, maybe there's something in the source that may help or give you some idea of what you may need to do. Here's the link: http://awdbedit.sourceforge.net/ -- try it out and let me know. If it does have that option and you just want to change it into a small tool then you can use the source -- if you need and help let me know.

Good luck and take care.
