kernel config for linuxbios

[Alessio Sangalli]

Hi. I've examined kernel patches freebios/src/kernel_patches and the 
patched kernel 2.4.20 avaiable at cwlinux.com.

I've noticed that there is a way to configure linuxbios support and 
linuxbios power management if I apply linux-2.4.19-sis.patch to a 
vanilla 2.4.19.

On the other hand, cwlinux's kernel has some great patches (like 
preemptive kernel) and a 2.4.20 version, but no "linuxbios support".

Which one should I use? perhaps it's only a matter to apply 
linux-2.4.19-sis.patch to a 2.4.20 kernel (some work is needed) to have 
the best kernel for linuxbios.

thank you

a deeper analisys showed me that both vanilla 2.4.19 and 2.4.20 don't 
have a well supported sis framebuffer; however, 2.4.19 with sis patch 
and 2.4.20-cwlinux have all the files to support it.

However I can't find a configuration key for the linuxbios 
powermanagement on 2.4.20-cwlinux. Is it enabled by default?

we need to get our minor patches into the cwlinux tree. These minor 
patches support power off etc. for sis chips.

kernel-source-linuxbios-2.4.20-CWLINUX_1.i386.rpm should contain sis patch
already.

Yes I have that exact file; I've compared the directory entries for the 
sis video framebuffer and I saw it was patched; however, in 
linux-2.4.19-linuxbios there is a specific menu' entry for linuxbios 
support:

Sound  --->
USB support  --->
Bluetooth support  --->
Kernel hacking  --->
LinuxBIOS  --->
---
Load an Alternate Configuration File
Save Configuration to an Alternate File

while in 2.4.20-cwlinux I can't find it. I was wondering if it was 
enabled by default. That menu, in 2.4.19-linuxbios contains:

<*> LinuxBIOS Support (NEW)
Linuxbios Options  --->

and Linuxbios options is:

[*] Linuxbios Power Management support? (NEW)
[*]  S    SIS 503 support? (NEW)
[ ]  P    PIIX4E support? (NEW)
