Hello! I believe I missed something, someplace, during the past time period.
(Long story, probably told the list to stop sending me stuff while I was away and promptly forgot to reset the list sittings.)
So, a question as framed by my subject: What hardware are we using for LinuxBIOS now? Are they specific flash devices that match the original? Or are the older DOC devices still supported also?
You know the drill, I'm planning on a new project, probably over the coming season and I am thinking of implementing LinuxBIOS for it.
And as it happens it just might be wearing a GEODE processor as opposed to the normal ones. Now for the AMD members who're working with the GEODE, any part suggestions? Boards of course I will defer to when I am ready to select one. Essentially the kernel suggests I2C for the GPIO points on the GEODE and gives specific pin-numbers, and this is the 2.4.33.3 member kernel. That's why I asked about the Norwhich board. -- Gregg C Levine hansolofalcon@worldnet.att.net "The Force will be with you. Always." Obi-Wan Kenobi

Better avoid DOC if possible, a "plain" flash chip is much nicer to deal with. Generally it's possible to put at least 512kbyte (4Mbit) on mainboards now, but some boards allow flash chips up to 2Mbyte in size, which easily fits a kernel and a small system.

With AMD's great support I think a Geode LX board is the most modern system you can find with LinuxBIOS that's a good fit for an embedded system.

I second that. The LX port is one of the best LinuxBIOS implementaitons we've ever had. It's a very professional job, and we can learn from it. Also, LX was the EVERYWHERE at the embedded systems conference last month -- it's the cpu du jour. Everyone had them.
So, LX is a great choice from the quality of the LB support, and from the ubiquity of the CPU.
thanks

Hi Gregg,
The Geode southbridge, CS5536, is companion to the Geode GX and LX processors. It supports either FWH or LPC flash parts on the LPC bus. It also supports booting from the flash controller that could have a DOC on it but it is very complicated and you would need to work with the DOC guys to get the SPL/IPL support. It is our experience that the slight cost of a separate ROM for BIOS is worth it.
More informationon the 5536, including the data book, can be found here: http://www.amd.com/us-en/ConnectivitySolutions/ProductInformation/0,,50_2330...
