You actually can build your own modules for the install kernel without
unresolved symbols: you just have to make sure that your kernel source
tree is configured properly.
These instructions are for RH7.2, adjust appropriately for RH7.3:
(a) The install kernel is 2.4.7-10, so install the kernel-source
RPM for that kernel.
(b) /usr/src/linux-2.4.7-10/configs contains all the .config files (the
file that 'make xconfig' or 'make menuconfig' writes at the end)
that RedHat used to build the various kernel RPMS. The one we
want is kernel-2.4.7-i386-BOOT.config.
cp /usr/src/linux-2.4.7-10/configs/kernel-2.4.7-i386-BOOT.config \
/usr/src/linux-2.4.7-10/.config
(c) Configure the kernel source tree:
cd /usr/src/linux-2.4.7-10
make oldconfig
make dep
(d) Now you can go to your e1000 driver source, and configure the
Makefile appropriately. Namely:
Change the KSP define to:
KSP := /usr/src/linux-2.4.7-10
(e) Make the driver, an you've got a module that will work with the
install kernel. Install it into the initrd.img, and make sure you
update modules.info and pcitable.
This only covers the boot kernel -- you'll need to do this again for the
live kernel, and make sure it gets installed onto the machine during the
%post phase, or else your install will go fine but you won't be able to
bring up networking after the reboot.
