The initial reading is done by the bios, a small program that lies in the permanent memory of the computer. It knows where to look for the bootloader in the CD, but this gives full control to the initramfs kernel, which needs to load nodules to be able to access the hardware parts (something like this, I'm not such an expert on these issues so I may be wrong in the details...).
Sometimes the same issue can happen in hard disks as well, the bootloader will load but then the actual kernel does not know how to access a particular kind of hard drive. -- intrepid daily alternate cd fails to find cd-rom on powerbook G4 https://bugs.launchpad.net/bugs/260608 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
