LinuxQuestions.org - Linux (CRUX 2.1) won't recognize/load my Network device on eth0

Hi, I've just installed CRUX 2.1, following the exact instructions in the CRUX Handbook 2.1 found on crux.nu, step by step.
when I got to the Kernel compilation (which is a thing I never did before). I did what I've been told here:

Quote:

Go to /usr/src/linux-2.6.11.7, configure and compile a new kernel.

$ cd /usr/src/linux-2.6.11.7
$ make menuconfig
$ make all
$ make modules_install
$ cp arch/i386/boot/bzImage /vmlinuz
$ cp System.map /

Remember to enable the following kernel options:

Code maturity level options --->[*] Prompt for development and/or incomplete code/drivers

File systems --->
Pseudo filesystems --->[*] /dev file system support[*] Automatically mount at boot

and when `make menuconfig` I was making sure those kernel options were enabled. I made no other changes in the kernel options except enabling ALSA. then when I loaded up CRUX, running `ifconfig` showed only 'lo'. then I tried to compile the kernel again, this time enabling PPP and making sure that Realtek PCI Ethernet Adapter is included there (as a module). again ifconfig only shows lo.
I have no clew what to do, maybe it's because I never compiled a kernel before, maybe because the kernel won't recognize my Ethernet network card, Maybe because I'm doing what I need to do with the module (but what DO I need to do??... :newbie: )... I don't know...

anyway, my Network card is "Realtek RTL8139 PCI Fast Ethernet Adapter", kernel version is 2.6.11.7, and Modem is ECI ADSL B-FOCuS 312+ .

any help?
