3. Ensure that the SRM console environment sysvar is set to 5 prior to
installing or booting Linux.
P00>>> set sysvar 5
P00>>> init
4. When switching back from Linux to Tru64 UNIX, verify that the SRM
console environment sysvar is equal to 12.
P00>>> set sysvar 12
P00>>> init
5. After installing Linux, set boot environment variables appropriately for
your installation. The typical values indicating booting from dka0 with the
first aboot.conf entry are shown in this example.
P00>>> set bootdef_dev dkb0
P00>>> set boot_file
P00>>> set boot_osflags 0
P00>>> show boot*
boot_dev dkb0.0.0.5.0
boot_file
boot_osflags 0
boot_reset OFF
bootdef_dev
booted_dev
booted_file
booted_osflags
6. From SRM enter the boot command. Example 3–5 shows an abbreviated
boot output. This example shows messages similar to what you will see
when booting Linux. The example is from a RedHat Linux 7.0 boot.
