Pliz Mod This Rom For me

Hi ... i would like to get some help about my old Desktop

I have a ECS mobo comes from a Pbell Unit with an AMI bios, and i can't really change any overclocking options, its really basic when you get into bios.
i have attached 2 snapshot in case someone willing to help might have an idea what they are dealing with.

i did make some research about this particular board and bios ...but there are no manuals or any helpful infos online... not even a bios update.

I would like to be able to overclock my machine a little bit and for that the bios needs to be updated to UNclocked...

there is a snapshot of my system info and the amiflash snapshot

there is no link to my bios online ..
however if someone helps me out, i can backup my current bios and upload it so that someone can work on it
I got the bios file here.....
