Creating a customized installation floppy

Applies to

SuSE Linux: Version 6.1

Request:

You want to replace the kernel contained on the installation floppy with a custom kernel.

Please note, that the topic described in this article is not covered by the free of charge installation support.

Procedure:

The following description assumes, that you have access to a running Linux system.

If you have to compile a kernel first, please make sure that especially the following options are activated (see 'make menuconfig'). We assume, that you are using a kernel of the 2.2 series.

In Loadable module support :

  [*] Enable loadable module support
  [*] Kernel module loader support

In General setup :

  <*> Kernel support for a.out binaries
  <*> Kernel support for ELF binaries

In Block devices :

  <*> Loop device support
  <*> RAM disk support
  [*] Initial RAM disk (initrd) support
Initial RAM disk (initrd) is only visible, if RAM disk support was activated (not as a module !).

In Filesystems

  <*> fat fs support                                      
  <*> msdos fs support
  <*> ISO 9660 CDROM filesystem support
  <*> Minix fs support
  [*] /proc filesystem support
  <*> Second extended fs support
  Network File Systems  --->
     <*> NFS filesystem support

NFS and iso9660 are only needed, if you want to use these media during the installation. The other filesystems (especially Minix and DOS) are needed in any case.

A good starting point for the configuration of the kernel are the configuration files of the precompiled kernels. The usage of these files is explained in the article Configuring installable kernels.

Further work :

Write one of the floppy images on CD1:/disks to a formatted floppy, e.g. according to the information in the article The SuSE Linux boot diskette. Compile the kernel and copy it to the newly created installation floppy :

mount /floppy
cp /usr/src/linux/arch/i386/boot/[b]zImage /floppy/linux
If there is not enough space on the floppy, you can erase one of the files net-mod.gz, scsi-mod.gz or other-mod.gz. Make sure in this case, that the compiled kernel contains all necessary functionality.

Unmount the floppy. Now you have a ready to use installation floppy with your custom kernel.
