New subject: making a custom boot disk

1 Oct 2003

Well, the PC that had the 2.4.20-20.9 kernel got hosed and I had to
reinstall.  It was a RH 9 install that had been updated.  

I installed this time with a Mandrake 9.1 distro.  I installed the
udpcast rpm and the kernel-udpcast rpm.  I then downloaded the 2.4.21
kernel from ftp.kernel.org and extracted it into /usr/src/linux-2.4.21/.
 Then I copied the udpc-config.txt file into that dir and called it
.config.  Then I edited the the Makefile and put in the -udpcast.  I
then did a "make oldconfig" which ran fine.  I also did the make dep &&
make bzImage && make modules && make modules_install and they all ran
fine.  Then I ran ./makeImage -t net-mod.tar.gz -k
/usr/src/linux-2.4.21/arch/i386/boot/bzImage  -f /dev/fd0 which seemed
to run ok.  I tried to boot off of the floppy and I get:

Could not find ramdisk image: initrd
boot:

I've obviously missed something...what am I forgetting to do?

I have compiled the network card module, but haven't tried to build it
into the kernel yet.  I'd like to get a working boot disk before I try
and make it hit the network.

 I followed the directions here

  custom boot disk by compiling my own kernel.

 Before doing anything I edited the Makefile and changed the
 "extra-version" parameter.  I just deleted what was there and put in
 "-udpcast".  I do a cd /usr/src/linux/2.4.20-20.9.  Then I copy the
 udpc-config.txt file to this dir and name it .config.  Next I do a "make
...
  oldconfig" which runs fine and so does the
"make dep".  However; when I
...
  do a "make bzImage" it runs for a while and
then it stops with errors
 regarding devfs?  What am I doing wrong? 
Could you post the exact error messages?

Also, are you sure that this is an original kernel (as distributed by
ftp.kernel.org). Indeed, the version number (2.4.20-20.9) strikes me
as somewhat odd...

...
  I even tried to download the RPM with a pre-compiled
kernel and its
 modules, but I'm unsure what do with it. 
Just install it with rpm -i , and then run makeImage

Or, alternatively, use the online image generator at
http://www.udpcast.linux.lu/cast-o-matic

...
   Can someone please point me in
 the right direction?  All I need is a boot disk with the Broadcom
 drivers that gets me udpcasting. 
Not sure whether the necessary module is in the pre-compiled kernel.

If not, try getting kernel sources from ftp.kernel.org, and compile
from these
