Your comments sound correct to me. I will not be installing modules that do
not come from CentOS, so I should not have a problem.
Here is a recap of what happened:
I followed the steps from an earlier posting from Akemi:
(1) prepare .spec by removing lines from %prep
(2) rpmbuild -bp kernel-2.6.spec
(3) go to BUILD (where .config is)
(4) make xconfig, as well as, adding the settings that I needed.
I my case it was support for ISA, ISAPNP and NE2000.
(5) edited the .config file in the BUILD dir: made '# i386' the first line in
the .config file.
(6) copy this .config back to SOURCES (using the original name
xxx.config)
7) rpmbuild -ba kernel-2.6.spec
I had a problem with a segfault during the 'rpmbuild -ba' process.
I changed the setting from 1 to 0 for the lines(multiple) that had:
'#define signmodules 1'.
However, after the 'rpmbuild -ba' finished, I used 'find /home/cs/redhat -name
ne.ko -print' and it did not find the module. I did a rpm --list of the
kernel rpm and it was there however. (Sorry about the redhat -- it should
have been centos.)
One other thing that caused me problems is that I did not know that rpmbuild
would not create all the needed directories. ie. BUILD RPMS are 2 that I know
of for sure.
I copied the kernel rpm to the gateway computer, did a 'rpm -ivh' for the new
kernel and rebooted.
I then ran system-config-network and was able to setup the ne2000 card in less
time than I takes to write about it.
Thanks for all your help, especially Akemi for staying with me during all
this.
