Great idea - just clip it onto the SPD EEPROM. A PIC and RS232
transceiver are all you need.

I would take this on except I am not sure what the table of contents would
look like.

On the subject dissasembly I would like to point out that (I guess) the DRAM
set-up code is probably within first 512 bytes of the BIOS, so you probably
could even dissasemble it by hand.

Has anyone other than me tried to buy from EksitData?
http://www.eksitdata.com/_uk/index.asp
This is who IOSS referred me to, and they still claim to have stock on
both PMC2 and PMC4.
What, we don't do business with the Swedes now? :)

I can verify that neither PC Extreme nor FrozenCPU have any in stock
at this time. I don't personally know of any other web vendors that
carried this item.

I am have serious issues getting my DDR SDRAM to initialize properly.
Is there any documenation that outlines the basic steps required and
what order to do it.
The memory controller I am using is a intel 855gme. I noticed in other
intel source files lots of comments curse about the lack of
documentation, I have noticed this as well. Does this mean that I
probably won't get this to work?
I am really at a loss of what to do next. I am having a hard time
debugging this, mostly because I don't exactly know what I need to do
in the first place.
Any tips for getting ram to work correctly?
Thanks,
Jon
Well, I think with the couple of tips and extra documentation (I
didn't know about the JEDEC docs) I'll keep chugging away at this
until the boss says to give it up. I would much rather use LinuxBIOS
on our product than a proprietary bios.
I did try using the register values from a known BIOS. However, that
didn't work as it isn't a static configuration. The docs do outline
many registers in the memory controller, but I have notice that when I
manipulate some undocumented ones to the values seen in a working bios
I get further (although not much) in the boot, leaving me to believe
not all the registers are documented :(.
Anyway I haven't given up yet, but at the same time, I won't be too
surprised if this doesn't work out.

We are working on getting LB going on a platform with 2 VGA devices.
One is an "on-board" ATI ES1000, meaning it is soldered down, without
a ROM attached to it (it is usually built into the platform BIOS
image).
The second VGA device is a plug in PCI card (XGI Z9S).
The PCI slot is on the same bus as the "on-board" graphics controller.
We would like to use the plug-in card as the VGA interface.
We tried the "off" option (in Config.lb) for the on-board PCI device,
but it still tries to load it as the VGA console (it does not work,
since there is no ROM).
We want the plugin card's option ROM to be run, and the "on-board"
controller should not be used. What is the correct way to achive what
we want? Basically, a way to hide the ATI controller would be
sufficient.
Thanks
