This file contains instructions for the SiS 630 based mainboards.
|

WARNING: we assume you've built kernels, know how to open up your PC, and how
|
||||
to yank the flash part out and put in a different part. There is NO WARRANTY,
|
||||
express or implied, with this software. In fact, if you don't know what you're
|
||||
doing, and you get careless, you're going to end up with a nice paperweight
|
||||
instead of a motherboard. YOU HAVE BEEN WARNED.
|
||||
|
||||
That said, this process is pretty hard to screw up.
|
||||
|
||||
The mainboards that are "known good" are:
|
||||
Matsonic MS7308E
|
||||
Winfast 6300MAX
|
||||
|
||||
Mainboards with SiS630 that we KNOW will not work are:
|
||||
Any ASUS (uses the wrong kind of flash part)
|
||||
Matsonic MS7308D (no Ethernet connector)
|
||||
|
||||
Vendors we have experience with that work:

The steps for loading linuxbios are simple:
|
||||
1) get a kernel, patch it, then build it
|
||||
2) config and build linuxbios
|
||||
3) get linux installed on your machine
|
||||
4) put a Disk On Chip into the flash socket
|
||||
5) Burn the chip
|
||||
6) hit reset. You're up.
|
||||
|
||||
---
|
||||
Step 1:
|
||||
o to www.kernel.org and get linux-2.4.0-test11
|
||||
|
||||
o Once you have pulled this file down and untar'ed it,
|
||||
apply the proper patch from the freebios/src/kernel_patches
|
||||
directory. Here's the current favorite for test11:
|
||||
linux-2.4.0-test11-sis630-fat-sisfb.patch
|
||||
|
||||
o Now copy config-2.4.0-test11.sis to .config, then
|
||||
make oldconfig
|
||||
make clean
|
||||
make dep
|
||||
make vmlinux
|
||||
|
||||
You now have a kernel for linuxbios.
|
||||
|
||||
Step 2:
|
||||
|
||||
o You need to get linuxbios source.
|
||||
cvs -d:pserver:anonymous@cvs.freebios.sourceforge.net:/cvsroot/freebios login
|
||||
|
||||
cvs -z3 -d:pserver:anonymous@cvs.freebios.sourceforge.net:/cvsroot/freebios co freebios
|
||||
|
||||
|
||||
o You now need to figure out where you want to put your build images.
|
||||
DO NOT PUT THESE IN THE LINUXBIOS SOURCE TREE.
|
||||
You want to put them OUTSIDE THE TREE, so you can always
|
||||
cvs update
|
||||
and not lose any of your build directory.
|
||||
Linuxbios does all the builds in a single directory, outside the
|
||||
source tree, much as BSD does. To build the initial Makefile,
|
||||
assembly stub, and ld script, we have a config tool.
|
||||
You need to build a config file (simple), run the config tool,
|
||||
cd to the build directory, and type 'make'.
|
||||
Here is a config file for the winfast 6300
|
||||
|
||||
# This will make a target directory of ./winfast
|
||||
# Note that this is RELATIVE TO WHERE YOU ARE WHEN YOU RUN THE
|
||||
# CONFIG TOOL. Make it absolute if you like
|
||||
target winfast
|
||||
|
||||
# WinFast 6300 MAX mainboard
|
||||
mainboard leadtek/winfast6300
|
||||
|
||||
# Enable Serial Console for debugging
|
||||
# It will come up at 115200,8n1
|
||||
option SERIAL_CONSOLE
|
||||
|
||||
# Enable MicroCode update and L2 Cache init for PII and PIII
|
||||
option UPDATE_MICROCODE
|
||||
option CONFIGURE_L2_CACHE
|
||||
|
||||
# Use the internal VGA frame buffer device
|
||||
option HAVE_FRAMEBUFFER
|
||||
|
||||
# Path to your kernel (vmlinux)
|
||||
linux /usr/src/linux
|
||||
|
||||
# Kernel command line parameters
|
||||
commandline root=/dev/hda1
|
||||
|
||||
|
||||
The target command names the build directory. The mainboard command
|
||||
names the mainboard. We have set options for a serial console which
|
||||
will get you linuxbios debug output via the serial port; updating
|
||||
microcode on the PIII (mandatory for coppermine!); configuring the
|
||||
L2 cache (harmless, leave it in); framebuffer init (leave it in
|
||||
if you want a console). You have to tell it where to find the vmlinux
|
||||
you build (the 'linux' command); and finally you need a commandline
|
||||
for now.
|
||||
|
||||
That's the file. Here's what it looks like when you run it.
|
||||
python LBConfig.py winfast.config ~/src/bios/freebios
|
||||
winfast is not a directory.
|
||||
I know I should make this, but I'm too paranoid
|
||||
To fix this, type
|
||||
mkdir -p winfast
|
||||
then run this program again
|
||||
|
||||
Note this first time, we got an error, since I forgot to make
|
||||
the 'target' directory.
|
||||
mkdir -p winfast
|
||||
|
||||
python LBConfig.py winfast.config ~/src/bios/freebios
|
||||
Will place Makefile, crt0.S, ldscript.ld in winfast
|
||||
Process config file: /users/rminnich/src/bios/freebios/src/mainboard/leadtek/winfast6300/Config
|
||||
Process config file: /users/rminnich/src/bios/freebios/src/northsouthbridge/sis/630/Config
|
||||
Added ram init file: northsouthbridge/sis/630/raminit.inc
|
||||
Process config file: /users/rminnich/src/bios/freebios/src/cpu/p5/Config
|
||||
Process config file: /users/rminnich/src/bios/freebios/src/cpu/p6/Config
|
||||
Process config file: /users/rminnich/src/bios/freebios/src/lib/Config
|
||||
Trying to create winfast/Makefile
|
||||
Trying to create winfast/ldscript.ld
|
||||
Trying to create winfast/crt0.S
|
||||
Check for crt0.S param file: /users/rminnich/src/bios/freebios/src/include/northsouthbridge/sis/630/param.h
|
||||
Adding include to crt0.S for this parameter file
|
||||
|
||||
OK, all those messages are normal. Now we do a make:
|
||||
|
||||
(for a full transcript, see later in the file)
|
||||
|
||||
We now have three files to be loaded into the Disk On Chip. The first
|
||||
is called docipl. It is 512 bytes. The second is called linuxbios.strip,
|
||||
and is the binary image of the linuxbios that gets loaded into Doc.
|
||||
The third file is you kernel, and is stripped and compressed,
|
||||
vmlinux.bin.gz
|
||||
|
||||
-rw------- 1 rminnich CIC-ACL 512 Dec 20 08:41 docipl
|
||||
-rwx------ 1 rminnich CIC-ACL 33494 Dec 20 08:41 linuxbios.strip*
|
||||
-rwx------ 1 rminnich CIC-ACL 756069 Dec 20 08:41 vmlinux.bin.gz*
|
||||
|
||||
|
||||
You're now ready to burn the Disk On Chip, but first ....
|
||||
|
||||
Step 3)
|
||||
Get Linux installed on your machine. You still have to do this first.
|
||||
We can't yet boot alternate media such as cdroms.
|
||||
Be sure and get a kernel running which has MTD on as MODULES.
|
||||
|
||||
Step 4) open the machine (LEAVE THE POWER ON), yank the flash, and
|
||||
plug in the DoC. We recommend you practice this first with the
|
||||
power off. Make sure that whatever you do, you are not shorting
|
||||
things out.
|
||||
|
||||
NOTE: YOU CAN HURT YOURSELF AT THIS STEP. We can't take any
|
||||
responsibility for what happens to you here. If you haven't
|
||||
done this, or are not trained, or have a history of getting
|
||||
hurt by hardware, DON'T DO IT.
|
||||
|
||||
Step 5) Run the following script:
|
||||
|
||||
Step 6) Hit reset. Linuxbios should come up in a few seconds.
