[Linux-ia64] IA64 Boot/Installer CD

[Nick Pollitt]

Could someone explain what the bare minimum requirements are for a bootable
CD on IA64.  I have a kernel and an initrd ready, but I'm not sure how to 
package them up.

Thanks,
Nick

Hi,

Here is how we do it.

1) Create a directory called cdroot.  Create a subdirectory called boot.

2) Inside the boot directory, place your kernel and your initial ramdisk.  
You will also want to put any efi apps or shell scripts that you might need.

3) From inside the cdroot directory, run the attached "mkboot" script.  This
will create a boot image for your cd.

4) Run the attached "mkiso" script to build the cd image.

5) Run the attached "mkcd" script to burn the image onto the CD.  The "mkcd"
script is used with an IDE CD-ROM burner, so you may need to adjust cdrecord
command for your hardware.
