Problem creating an RTAI-enabled kernel

[Raja.Hayek@xxxxxxxxxxxxxx]

I am trying to build an RTAI-enabled
kernel o my linux computer, in preparation for installing an RTAI into
that kernel once ready.

Mainly, I have installed Mandrake 8.1
linux on the computer. Next, I wanted to rebuild the kernel.

After booting into the new kernel and
logging in, I fail to start X Windows. Namely, if I enter the command startx,
this is the message I get back:
        Fatal
server error:
        open_framebuffer:
failed to open /dev/fb0 (no such device)

It seems that other services are working.

My computer is a Pentium-III with an
SBC81613 motherboard, and an S3 ProSavage4 AGP 4x graphics controller.


Thanks in advance.

The build steps were as follows:

1.        I
downloaded the file  linux-2.4.17.tar.bz2.
I followed the steps detailed below to install and rebuild (my setup had
originally taken place in a directory called /home/tools):


2.        decompressed
the tar file
         
      tar --bzip2 -xvf linux-2.4.17.tar.bz2

3.        renamed
the original linux directory to linux-2.4.17
         
      mv linux linux-2.4.17

4.        copied
the patch file patch-2.4.17-rthal5g to my new linux directory, and applied
the patch
         
      patch -p0 -i /home/tools/linux-2.4.17/patch-2.4.17-rthal5g


5.        to
configure the kernel, I copied and "made" the config file, all
inside the my /home/tools/linux-2.4.17 directory. I went through the configuration,
selecting/de-selecting the options as applicable. 
         
      cp /boot/config .
         
      make config

6.        continued
the make process, as follows
         
      make dep
         
      make clean
         
      make bzImage
         
      make modules
         
      make modules_install
         
      
This problem occurs whether I accept
or reject support for frame buffers (the CONFIG_FB option) during the kernel
build process in step 5 above.
