Description |
Examples |
Where:
| -file filename | Specifies the name of a file to load into the system. For booting from Ethernet, this name is limited to 15 characters. Use the set boot_file command to set an environment variable that specifies a default boot file. |
| -flags data | Specifies additional information
for the operating system. Use the set boot_osflags command to set an environment
variable that specifies a default boot flag values. Tru64 UNIX boot flags. |
| -protocols enet_protocol | Specifies an Ethernet protocol(s) that will be used for a network boot. Values may be mop or bootp. |
| -halt | Forces the bootstrap operation to halt and invoke the console program after the image is loaded and the page tables and other data structures are set up. |
| boot_device | Specifies a device path or list of devices that the firmware will attempt to boot. Use the set bootdef_dev command to set an environment variable that specifies a default boot device. |
| >>>boot | Boots the system from the default boot device. |
| >>>boot ewa0 | Boots the system from Ethernet port ewa0. |
| >>>boot -file dec2.sys ewa0 | Boots the file named dec2.sys from Ethernet port ewa0. |
| >>>boot -protocol bootp ewa0 | Boots using TCP/IP BOOTP protocol from Ethernet post ewa0. (Make sure the environment variables ewa0_protocols and ewa0_inet_init are both set to BOOTP before booting.) |
| >>>boot -flags a | Boots the system from the default boot device using flag settings 0,1. |
| >>>boot -halt dka0 | Loads the image from disk dka0, but remains in console mode. |
| >>> boot Trying MOP boot. ... ... ... | Successful boot from a system that is set to secure mode. In this example the boot command is equivalent to:(boot eza0.0.6.0 -file myfile.sys -flags 0) |
Tru64 UNIX boot flags can be stored in the boot_osflags variable or typed in along with the boot command. The possible boot flags for Tru64 UNIX are:
