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 4.3, “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. You can pass extra boot parameters to
debian-installer at the end
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 5.4, “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).
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.
