&boot-installer-intro-net.xml; On machines with OpenBoot, simply enter the boot monitor on the machine which is being installed (see ). 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. &boot-installer-intro-cd.xml; Most OpenBoot versions support the boot cdrom 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 Bad magic 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 . 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.
