2.6.0-test11 kernel questions

Pcghost · 12-05-2003, 03:10 PM

I have just completed my first successful (bootable) compile of the 2.6.0-test11 kernel and am about to do it again to include stuff I forgot or was broken (sound) by the new setup. I have just a few questions I haven't found definitive answers for yet. Hopefully someone out there can enlighten me and save me hours of compiling,

#1. Is it true that ide-scsi is no longer used, ie. can I remove the hdc=ide-scsi tag from the boot loader?

#2. For some reason when I boot the 2.6 kernel I see nothing on the screen until the x-server starts and goes to graphical log-in. Is there something I forgot to compile in that deals with that? (possibly just answered)

#3. (related to #2). Is the fact that there is no longer a SuSE picture and the whole F2 for details border around my screen on boot a symptom of the problem in question 2? Or is this lost forever by not using a SuSE tweaked kernel?

#4. Is there anything wrong with recompiling using the same sources over and over again until I get it right, or should I reinstall the sources each time?

Overall I must say I like the new build method way better now that I am figuring out what has changed. Much less room for me to screw it up (except during config

)

As far as I know you use that for writing cd's. You have to have generic scsi-support in the kernel and your boot loader needs to tell the kernel to use that driver for your cdrom(hdc).

#2. For some reason when I boot the 2.6 kernel I see nothing on the screen until the x-server starts and goes to graphical log-in. Is there something I forgot to compile in that deals with that? (possibly just answered)

You have to have the consol drivers installed and Virtual Terminal on under the character devices.

#3. (related to #2). Is the fact that there is no longer a SuSE picture and the whole F2 for details border around my screen on boot a symptom of the problem in question 2? Or is this lost forever by not using a SuSE tweaked kernel?

I think it will come back after you get the terminal back.

#4. Is there anything wrong with recompiling using the same sources over and over again until I get it right, or should I reinstall the sources each time?

Keep your kernel config. You only need to set it up once.

Hopefully someone out there can enlighten me and save me hours of compiling,

You can build the kernel on a faster machine running linux then install it on the machine you would like it to run on...

Hope this helps... Have fun in kernel land..

You no longer need to use ide-scsi in 2.6.0. and in fact it is recommended that you don't because the new ide driver is much improved and is able to write to cd's now.
I agree you need console driver.
The bootsplash is a patch. There is no 2.6.0-test11 patch available yet but you can probably make the 2.6.0-test9 patch work. What I do is if any hunks fail I install them manually with an editor.
All you need to do is a make clean, but the new 2.6.0 might do that automatically because I've noticed it makes all the modules again even if I don't do a make clean.

I was curious if this has changed... Cool.

I've also just compiled a successful copy of 2.6.0-test11 for the first time, and when I select it in LILO I too get no details, but I'm not sure what this means:

Are these Kernel selections which I have missed? Or are they selections I can make elsewhere?

In Device Drivers under

Character Devices
Select Virtual Terminal and
Support for console on virtual terminal

Graphics support
Console display driver support
Select VGA text console and
Video mode selection support

For building the 2.6 kernel

Take and read the following:

http://ftp.kernel.org/pub/linux/kern...loween-2.5.txt

You need to get the module-init-tools from the repository of you distro.

Use lspci -v to help select your hardware. This will be helpful for configuring the 2.6 kernel.

make mrproper
make menuconfig
make
make modules_install
make install

Then modify you lilo.conf or grub.txt

make install installs vmlinuz into the boot directory along with System.map
It creates a symbolic link to you old vmlinuz -> vmlinuz.old and System.old

All you need to do is add entry for the old vmlinuz. I use lilo.conf

This is mine....

image=/boot/vmlinuz
initrd=/boot/initrd-2.6.0-test11
label=Linux2.6
read-only

** This would be you redhat config. **
image=/boot/vmlinuz.old
vga=791 #for 2.4 kernels only
append="hdc=scsi hdd=scsi apm=power-off nomce"
label=Linux2.4
initrd=/boot/initrd.gz
read-only

If you are using lilo, issue lilo -v or modify you menu.lst for grub.

Hope this helps. The more people use 2.6 the better.
