Info and help

Hi there people. I´d like to have some info on the project, because I didn´t understand it very well, and didn´t find many info on the net(I recognize I didn´t googled a lot). Can I install openbios on any x86 motherboard ? Or only the ones which implements the open firmware standard ? If so, is there a list of which hardware/mobo are compatible ? My problem is: I have and old computer... an Intel pentium 4 2.6ghz on a Intel D865PERL motherboard. Recently I acquired an used nvidia 6800 GS video card, and I´m experiencing freezes and lockups, and for what I had researched, seems to be a problem with AGP FAST WRITE option turned on. The problem is: I don´t have the option to turn it off on my bios anymore.... My diagnostics (everest) says it´s enabled. When I bought my computer in 2004 I remebered of this option, and at that time my gforce 4400 mx card didn´t support this option so I had to turn it off. Some years later I upgraded my bios, and didn´t miss this option. Now I´m looking for it and it´s not there anymore. I tried flashing 5 older bios to my card, to see if this option would "come back", but no luck. Now I doubt even myself I had ever had this option.... that´s where I got the old bios from intel server: ftp://download.intel.com/design/motherbd/rl/ Then I remebered of this openbios project, and I thought: If I can use this bios, and turn off this option, it´ll solve my problems! So, is there any chance I can do that ? Thanks in advance, and congratulations for the project. -- Filosofia de software livre: Informação é de graça pessoas não são contribuidores não tem preço.
