Hi guys

for me this is the second time that I try to compile the linux kernel. The reason is that I have to change a IDE class driver so that my 3 SATA2 HDD will run with DMA support. Currently they don't do.
I got the description from nVidias nForce problem web site what to change.
The first time I followed their description but :

I overwrote my original kernel
-- but I want it to be offered as an alternative in the GRUB boot menu

The newly build kernel told me that there are no matching modules

The X-Server didn't start. Before I had successfully installed the original nVidia driver for my Model: "ASUSTeK GeForce 6600". But now after compiling X doesn't start.

Here is what HW I have and what I did to get a new kernel. I hope someone can guide me to a better new kernel ;-)

CPU : Arch: X86-64
Vendor: "AuthenticAMD"
Model: 15.47.2 "AMD Athlon(tm) 64 Processor 3200+"

Motherboard : ASUS A8N-E

3xSATA2 Model: "WDC WD1600JS-00M"

Memory : 1GB

Grafikkard : Model: "ASUSTeK GeForce 6600"

SuSE 10.0

linux 2.6.13-15.8-default #1 Tue Feb 7 11:07:24 UTC 2006 x86_64 x86_64 x86_64 GNU/Linux

1. kopie original kernel to now directory
2. Change amd74xx.c according to nVidias notes.
3. get original configuration
----zcat /proc/config.gz > .config
----make oldconfig
4. compile
----make bzImage
----make modules
5. install new kernel
----INSTALL_PATH=/boot make install
6. install new compiled modules
----make modules_install

REBOOT.

So, if someone can tell me what it needs to get an additional kernel BESIDE the original one ?

Thanks

that is a standard feature of grub. And the reason why you should use it.

First of all you have to configure and then compile the new kernel:
make menuconfig
make && make modules_install

Then you copy the bzImage file to your /boot (usually from /usr/src/linux/arch/x86_64/bzImage):
cp /full_path_to_file/bzImage /boot

Then you have to edit the menu.lst file in /boot/grub/menu.lst so it looks like mine:
timeout 3
default 0
fallback 1

#For booting GNU/Gentoo Linux current
title Gentoo 2.6.15-current
root (hd0,0)
kernel /boot/2.6.15-gentoo-r5-current root=/dev/hda3

#For booting GNU/Gentoo Linux test kernel
title Gentoo 2.6.15- new test kernel
root (hd0,0)
kernel /boot/2.6.15-gentoo-r5-test root=/dev/hda3

Dont forget to set the correct parameters for your root partition (it means you will probably have to change the root=/dev/hda3 to your partition location!)

Good luck.

Thanks to all your help.

I found out myself that I have to change the version number in the Makefile. It just wasn't enough to copy the original sources into a new directory.
I don't need to do the make menuconfig thing. The first thing I whanted to do was to use the current configuration. And to get this configuratin I followed the steps in my SuSE 9.3 book.

> zcat /proc/config.gz > .config
> make oldconfig

I didn't start compiling my kernel again. But I found a very nice document in that I found everything I need to know about compiling kernels from scratch, from PRM, for SUSE , with explanation of possible pitfalls and many interesting things.

I'm not allowet to post URLS since I have to post at least 3 times in this forum. So I will replace the / -> _ and the . -> : and hope you find this document as informative as I do.
