All the following commands are to be run from the OBP and not the OS. They are only valid on Sparc hardware that uses the openboot rmware. The eeprom command can be used from the OS to view or set openboot rmware variables.Show the value of the auto-boot? variableprintenv auto-boot?Set the system to not auto bootsetenv auto-boot? falseRestore the system default for auto bootset-default auto-boot?Show the default boot deviceprintenv boot-deviceList the actual device path for the disk device aliasdevalias diskList all openboot variables, current, and default valuesprintenvShow devices seen by openbootshow-devsShow help on all OBP commandshelpBoot the system into single user mode from the CD ROMboot cdrom -sBoot the system into single user mode using the default deviceboot -sReset the systemreset-all Check to see if gcc is installed on systempkginfo SMCgcc /or/ pkginfo | grep gccRemove the gcc packagepkgrm SMCgccCheck the installation of the gcc (SMCgcc) packagepkgchk SMCgccShow revisions of packages on systemshowrev -pGet expected le info and source package for a lepkgchk -l -p /usr/sfw/bin/gccVerify all packages (and les) on the systempkgchkDisplay information about a packagepkgchk -l SMCgccDisplay version information about an installed packagepkginfo -x SMCgccList all patches on the systemshowrev -p /or/ patchadd -pList patches applied to the SUNWckr packagepkgparam SUNWckr PATCHLIST smpatch and updatemanager can be used to manage system patches.
