Is there a way for linuxbios to initialize the graphics hardware directly? besides making linux use the framebuffer directly on bootup. and maybe making filo use the framebuffer too. -- things i hate about my linux pc: 1. it takes more than a second to boot up 2. keeps asking about filenames and directories 3. does not remember what i was working on yesterday 4. does not remember all the changes i have ever made 5.cannot figure out necessary settings by itself

If the hardware was standard then yes but each graphics mfg does it differently and its hidden by the VGA bios. Think of each graphics card as a graphics northbridge. You have to eanble all the right bits, turn on the video ram, etc. On 99% of graphics cards the info on how to do this is not known. So you have to run the vga bios to do it. -- Richard A. Smith

ugh!!! and the vga bios is running at 16 bit mode? and its slow with all its timing loops and other stuff. which graphic cards are in the other 1%? hah! this is another argument for ogp. i have to start studying fpgas now. i need an open graphics card that boots at a fraction of the speed of current cards and boots straight into framebuffer mode. -- things i hate about my linux pc: 1. it takes more than a second to boot up 2. keeps asking about filenames and directories 3. does not remember what i was working on yesterday 4. does not remember all the changes i have ever made 5.cannot figure out necessary settings by itself

this is part of a bigger issue. I am thinking of starting a project called System Libre (a take on software libre) which would be open from the ground up. This is a response to many bad trends in our business, where the systems are gradually getting locked up (xbox, EFI, etc.) and we can't do much with them. So I like your idea. ron

Count me in, I'll help where I can. This is one of the main reasons why I got interested in LinuxBIOS - to have a 100% Free Software system, from the ground up.

For video, check out: http://wiki.duskglow.com/tiki-index.php?page=Open-Graphics I think It's been going on for a couple of years now. As for FPGA's, a high end Virtex+ builtin Dual PPC cores gets you there pretty fast. Only problem is the price (for the chips and the software). Not sure how well a spartan-level fpga would work out as SOC or chipset. But the price is right (free software, relatively cheap chip). Check out: http://www.fpga4fun.com

I would like to help with that too. The open graphics project is doing the same thing for graphics cards. -- things i hate about my linux pc: 1. it takes more than a second to boot up 2. keeps asking about filenames and directories 3. does not remember what i was working on yesterday 4. does not remember all the changes i have ever made 5.cannot figure out necessary settings by itself
