Re: [gentoo-dev] Install on a compaq proliant / howto make own boot-cd?

[Sylvain]

Hello !

I already posted a very short answer dealing with that :
the subject was "building a stage 1 iso".
Anyway, you needs very few things :
1) A booting kernel for your hardware
2) a ramdisk similar to the one included in the 'normal' gentoo cd
  (maybe you will have to include right kernel modules in it to support your hardware)
3) the isolinux.bin file which allow to boot from a cd without limitations
    inherited from the floppy emulation (the limitation is the size of the ramdisk)
4) the stages archives you want on this cd (you can also add prebuild packages for example,
   or some documentation, for example)

To generate the iso image, you will have to mkisofs the directorie isolinux and your
other files (stage archive, ...) with at least those params :
-R -b isolinux/isolinux.bin -c isolinux/isolinux.cat -no-emul-boot -boot-load-size 4 -boot-info-table
(You really should have a look at the mkisofs man page)

The isolinux must contain
- the kernel (don't name it somathing like foo.img)
- the ramdisk : a small filesystem (probably ext2) containing basics tools, required library for those
  tools, kernel modules, and anything else you want. The ramdisk is very often named someting like 'initrd'
  or 'initrd.gz'
- the isolinux.bin file (a kind of boot sector)
- the isolinux.cfg, in which you configure wich kernel and wich ramdisk you may want to use

the other directory of the CD are free, for what you want

You should have a look at the existing ramdisk :
gunzip initrd.gz
mount -o loop initrd /mnt/initrd

Documentation for isolinux : http://syslinux.zytor.com/
Ramdisk documentation : (from "The Linux Bootdisk HOWTO"
http://www.tldp.org/HOWTO/Bootdisk-HOWTO/buildroot.html
/usr/src/linux/Documentation/ramdisk.txt
/usr/src/linux/Documentation/initrd.txt

Now, i am sure it will help (if read ...)

Regards
