[Mactel-linux-devel] Bulding a live CD

[Thomas G. <sit...@st...>]

Hello,
I build a life CD a long time ago using a shell script to make it 100%
reproducable (I hated to adopt knoppix again and again when a new one
was released). However this morning I tried to adopt this live cd for Mac
Mini and ran into two problems:

        - First the absolut showstopper: Mac Mini doesn't work with the
          cdrom. Has anybody the CDROM under Linux on Mac Mini working?
          hda: ATAPI 24X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache

        Uniform CD-ROM driver Revision: 3.20
        hda: cdrom_pc_intr: The drive appears confused (ireason = 0x01)
        hda: cdrom_pc_intr: The drive appears confused (ireason = 0x01)
        ...

        I don't remeber from memory what that flag in ireason means but
        I look it up later in the ATAPI spec.

        - And the not so hard showstopper was: How do I get a Linux
          kernel/initrd/elilo/refit compilation on a cd so such my apple
          will boot from it when I press c during boot? Are there some
          instructions available or could someone tell me how to get
          there?

Sincerely,
        Thomas

my fault. This is working. I just compiled the IDE driver in and dropped
the libata.enable_atapi=1 from the command line.

The rEFIt ReadMe has instructions how to install rEFIt to a HFS+  
volume and bless it such that the Mac will boot from it. It also has  
a few words how to add elilo to the mix. To get the whole thing on a  
CD you have two options:

1. Make the whole CD HFS+ (like gimli's current Ubuntu Live CD). Make  
a sufficiently large disk image on the Mac, copy everything into it,  
bless the boot loader, unmount it, burn it to CD. Make sure you have  
a kernel with hfsplus compiled in.

2. Use the instructions I posted to mactel-linux-devel two days ago  
to make a CD in ISO9660 format with rEFIt, elilo and the kernel in a  
HFS+ image added as an El Torito boot image.

Hope this helps,
chrisp
