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. Jon On 11/29/06, Drew Lundsten <[EMAIL PROTECTED]> wrote: > This is depressing, definitely.
