[LinuxBIOS] resizing a stock bios
by Adam Talbot 13 Feb '06

13 Feb '06

How do I resize a stock bios? The current rom is 512kb and so is the flash chip. I have a smaller flash chip that I would like to use to free up the big chip. This means i need to make a 512kb rom file fit on a 256kb rom :-). Is this even possible? -Adam

[LinuxBIOS] Gigabyte GA-8I848P-G support ?
by Simon Kellett 11 Feb '06

11 Feb '06

Hi, I am interested in this project as a home user who does leave his computer running, and would like a fast startup time !! (And a nicer splash then the BIOS screen would be nice to !!). >From what I can see the project is mainly orientated to servers or embedded systems, but I wonder if my board may work ? The website is a little vague on supported boards (out of date ?) so I have answered the questions from one of the FAQ entries below. Thanks for any pointers, Simon ============ If the above sources don't help, please send the following to the Mailinglist: * Step 1: A very brief description of your system: CPU and mainboard and optionally other important details.

[LinuxBIOS] what is the fastest speed of BIOS socket?
by Miernik 07 Feb '06

07 Feb '06

What is the transfer rate and latency of the interface between the CPU and the BIOS socket in motherboards like Via Epia or Tyan Opteron boards? What I am thinking to do is to put very fast SRAM there (it should work, shouldn't it?), battery backed up of course, and run the LinuxBIOS and kernel XiP eXecute in Place (without copying to RAM). Would that work? Imagine I could put 8 MB of fast SRAM there. Now, would that make sense, is the interface as fast as the FSB if I have a 200 MHz FSB for example? If I put some SRAM with random access time below 5 ns in there would it communicate with the CPU faster than DRAM in hte DIMM sockets is? Or at least as fast? With the intention of running it XiP. --

Ward, I am booting with Etherboot v5.4.1. LinuxBIOS is from November sometime. I think this version is from Yh Lu. He helped with getting it to work. I just tried to build it from the current (r2169) svn, and it doesn't boot: LinuxBIOS-1.1.8_s2891_Normal Thu Feb 2 22:15:06 UTC 2006 starting...

[LinuxBIOS] Fun easy question. 512Kb or 256Kb
by Adam Talbot 07 Feb '06

07 Feb '06

Fun easy question. Messing about with my new board, and have an easy question. So I have both the SST 39SF020 and the 39SF040 flash chip. My payload is just filo; so I can fit Linuxbios on the 256Kb or the 512Kb flash chip. Is there any reason to use the 512Kb? Faster, slower, any thing else like that? -Adam
