Information About The Installed System - IBM 88553RX Installation Manual

3. The startup function is called, enabling stacks, decompressing the kernel, and
identifying the processor type.
4. The start_kernel function is called, starting all memory procedures, and
kernel cache, and executes /sbin/init.
5. The boot procedure continues.
IA-32 applications
SLES 8 provided the IA-32 runtime environment installed by default. This
environment contains glibc, ncurses, C++, and X11 libraries to guarantee
compatibility with IA-32 applications.
If you want to compile any application from code source to IA-32 platform, it is
still possible, and you may also compile it to IA-64. This will offer you the
possibility to still use older IA-32 applications, if you don't have the source code
or you do not want to recompile it to IA-64.

4.4.6 Information about the installed system

Our recently installed Linux system can offer us some information about the
x455, such as CPU details, memory, and some other useful information. The
following sections outline what the Linux kernel found about the CPU used during
our tests. We used the /proc virtual file system to obtain this information.
CPU information
Linux recognizes the x455's processors as an Itanium 2, from the IA-64
architecture. During our tests we had two-node configuration, each server with
four processors and we will find all the information regarding every CPU, the
Example 4-2 shows the two last processors.
