Booting from the network requires that you have a network connection and a TFTP network boot server (DHCP, RARP, or BOOTP).
The installation method to support network booting is described in Section 4.4, “Preparing Files for TFTP Net Booting”.
On machines with OpenBoot, simply enter the boot monitor on the
machine which is being installed (see
Section 3.6.1, “Invoking OpenBoot”).
Use the command
boot net to boot from a TFTP
and RARP server, or try
boot net:bootp or
boot net:dhcp to boot from a TFTP and BOOTP
or DHCP server.
The easiest route for most people will be to use a set of Debian CDs. If you have a CD set, and if your machine supports booting directly off the CD, great! Simply insert your CD, reboot, and proceed to the next chapter.
Note that certain CD drives may require special drivers, and thus be inaccessible in the early installation stages. If it turns out the standard way of booting off a CD doesn't work for your hardware, revisit this chapter and read about alternate kernels and installation methods which may work for you.
Even if you cannot boot from CD-ROM, you can probably install the Debian system components and any packages you want from CD-ROM. Simply boot using a different media, such as floppies. When it's time to install the operating system, base system, and any additional packages, point the installation system at the CD-ROM drive.
If you have problems booting, see Section 5.3, “Troubleshooting the Installation Process”.
Most OpenBoot versions support the
command which is simply an alias to boot from the SCSI device on ID 6
(or the secondary master for IDE based systems).
Floppy images are currently only available for sparc32, but, for technical reasons, not for official releases. (The reason is that they can only be built as root, which is not supported by our build daemons.) Look under “daily built images” on the Debian Installer project website for links to floppy images for sparc32.
To boot from floppy on a Sparc, use
Stop-A -> OpenBoot: "boot floppy"
Be warned that the newer Sun4u (ultra) architecture does not support
floppy booting. A typical error message is
number in disk label - Can't open disk label package.
Several Sparcs (e.g. Ultra 10) have an OBP bug that prevents them from booting (instead of not supporting booting at all). The appropriate OBP update can be downloaded as product ID 106121 from http://sunsolve.sun.com.
If you are booting from the floppy, and you see messages such as
Fatal error: Cannot read partition Illegal or malformed device name
then it is possible that floppy booting is simply not supported on your machine.
If you cannot boot because you get messages about a problem with “IDPROM”, then it's possible that your NVRAM battery, which holds configuration information for you firmware, has run out. See the Sun NVRAM FAQ for more information.
