Kernel recompilation question

satimis · 11-22-2004, 02:56 AM

Hi folks,

FedoraCore2

I tried a whole day unable to get my old scanner (SnapScan 310- connected to a ISA SCSI card) to work which has been working on this box while running RH8.0. It is still working on WinME on this box (a removable hard drive).

Now I want to recompile the kernel. Before doing so please advise;

1)
# cat /proc/version

Code:

Linux version 2.6.9-1.3_FC2 (bhcompile@porky.build.redhat.com) (gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)) #1 Mon Nov 15 14:46:43 EST 2004

# rpm -qa | grep kernel

Code:

kernel-2.6.5-1.358
kernel-2.6.8-1.521
kernel-utils-2.4-9.1.131
kernel-2.6.9-1.3_FC2

I suppose to recompile "kernel-2.6.9-1.3_FC2". If I'm wrong please advise.me Tks.

2)
Before recompiling kernel is it possible to check whether ISA support has been enabled.

3)
Re /usr/src/KERNEL/Documentation/scsi/ directories

I could not locate them.

# find / -name KERNEL
find: /proc/2714/task: No such file or directory
# find / -name aha152.x.txt
find: /proc/2714/task: No such file or directory
# find / -name Documentation
find: /proc/2714/task: No such file or directory

4)
I have not recompiled kernel for prolonged time. Can folks please give me some guide lines in brief on following steps;

cd /usr/src/linux
make config
make dep
make clean
make zlilo

whether I have to work on runlevel 3.

I'm running GRUB. Should I change the last step to "make grub" Any precaution to be taken?

TIA

B.R.

I'm not 100% sure but I think you have to install another rpm to get the kernel source. I'm pretty sure Fedora just installs the binary kernel with no source code. If you have apt-get check the repositories to see if the source code rpm is available.

2) in /usr/src/<kernelversion>, there is a hidden text file called .config, which has the current kernel configuration.

3) note that /usr/src/KERNEL should be replaced with /usr/src/<kernelversion>, i.e. the version number of the kernel you're using. In your case, /usr/src/linux-2.6.9-1.3_FC2, or something similar.

4) check the /usr/share/docs area of your system for howto's. You probably have one relating to kernel compilation.
