Chapter 3. Boot Process, Init, and Shutdown 75

Warning

If your computer does not power itself down, be careful not turn off the computer until you see a

message indicating that the system is halted or ﬁnished shutting down.

Failure to wait for this message will mean that you may be turning off the machine before your hard

drive partitions are unmounted. This can cause ﬁlesystem corruption, even to the point where your

system may not boot the next time it attempts to start up. Be patient when halting your system.

3.7. Differences in the Boot Process of Other Architectures

Each computer architecture supported by Red Hat Linux boots the operating system in a different

way. However, once the Red Hat Linux kernel begins booting and hands off the boot process to init,

the same events happen on each architecture in exactly the same way. The only difference is in the

way Red Hat Linux ﬁnds the kernel to load it in order to start init.

For example, the Alpha architecture uses the aboot boot loader, while the Itanium architecture uses

the ELILO boot loader.

Consult the installation information for each of the architectures for detailed information about the

different boot methods.
