Option Parameters for Linuxbios.
by sivakumar 11 Jan '03

Hi all, Can any one help me in understanding the following parameter used for the configuration of the LinuxBIOS. biosbase 0xffff0000 rambase 0x00000800 option XIP_ROM_BASE=0xffff0000 option XIP_ROM_SIZE=0x10000 option STACK_SIZE=0x2000 option ZKERNEL_START=0xfff40000 option ZKERNEL_MASK=0x3ed Also I have one more query, When executing the linuxbios, it is executing the instrcution twice (i.e., I am getting output twice). I have attached the serial console output below. How to get rid of this? LinuxBIOS-1.0.0 Sat Jan 11 18:18:32 IST 2003 Revision - 4 (four)starting...

Geode sc2200 vga
by John Allen 11 Jan '03

11 Jan '03

I have successfully built LinuxBIOS to load a kernel from my IDE drive and boot using a serial console. Now I would like to test the VGA funtionality of my board. Has anyone had any experience getting the VGA to turn on and work within LinuxBIOS and/or Linux? John

Greetings, I have made the initial commit for this board/chipset Currently, I have it booting into Linux with everything appearing to work. Early next week will be testing, getting primary/fallback builds working and general cleanup.

missing _estack
by gnat＠gnat.ca 11 Jan '03

11 Jan '03

Hello, I've been trying to figure out how these things are setup. If I use one of the sis5xx mainboard configs, I get an error stating that _estack is undefined. Where is it supposed to be? Obviously, it has something to do with setting up a stack. I just don't understand where it is supposed to come from. Since I'm patterning my mainboard (sis530 based) on those as examples. This causes a small problem. Can anyone help me? -- Nathanael Noblet ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/

via epia 800
by Jarmo Torvinen 11 Jan '03

11 Jan '03

Hi all, I'm building a (multimedia) set-top-box using Via epia 800-mainboard. The system works fine with linux except the bios boot-delay is too long. I was hoping if someone could point me to a simple documentation howto setup linuxbios for this board for reduced boot time? I have downloaded the rom-image from http://www.cwlinux.com/downloads/linuxbios-sdk/images/romimages/epia.rom but I'm still wondering if it is good for booting from hda1? Does the kernel installed in hda1 have to be the cwlinux-patched version or may I use my own vanilla-kernel? I think there will be lot of questions regarding this matter in the future because of the numerous people building around this mobo, so maybe someone who got it working could write a simple HowTo or FAQ of this "issue".

Geode debugging
by Adam Bezanson 11 Jan '03

11 Jan '03

Anyone know what is typically used for debugging a Geode x200 based design? By this I mean a JTAG/BDM or ICE for debugging say, LinuxBIOS and the Linux Kernel/Linux device drivers. I think this would be needed to support audio (VSA/SMM support) since getting it working without an ICE of some kind would be next to impossible. I can't really find any info on the web about it other then here: http://www.fs2.com they make an ISA-GEODE but it only seems to support GX2 based processors. Any suggestions? Thanks, Adam

AMD 760MPX
by Jarmo Tulonen 10 Jan '03

10 Jan '03

Hi, What is the present status of LinuxBIOS for this chip set ? I think someone was working on it. We should make an implementation for Tyan Tiger MPX (S2466), so we are interested in what already exists (especially for the southbridge). And also if there is something we can help with. Regards Jarmo

Re: Booting from floppy
by Big Pilot 10 Jan '03

10 Jan '03

So there are two issues: a) DOS isn't supported and b) the floppy as a boot device isn't supported. That will make it a very difficult sell for mobo manufacturers. Can you imagine me buying a Linux PC with LinuxBIOS and it crashing. How am I going to repair it then? ----- Original Message ----- From: Adam Sulmicki <adam(a)cfar.umd.edu> Date: Fri, 6 Dec 2002 12:50:07 -0500 (EST) To: "Ronald G.

Terry, If you could get a chance to review the document below or pass it on to the appropriate party that would be great.
