It's not really greater than normal bit capabilities... The processor supports it in hardware, and individual processes still run in a 32-bit address space, just mapped in from a larger pool of pages.

I wish to install Red Hat linux 7.1 on a machine with 16mb of EDO Ram. When I enter the instalation process I am told 'You do not have enough memory'. Is there a way to install RHL with only the 16? Or will I have to upgrade and buy some very expensive EDO.

Where can I get a list that maps the each Linux version to corresponding 32/64 bits model?
e.g.
OS -> Model (ILP32, LP64, ...)
RHLE3 -> ?
RHLE4 -> ?
RHLE5 -> ?
...
It would be better if there is such a list that contains most of current UNIX OS versions.

openssl_ia32cap
OPENSSL_ia32cap(3SSL) OpenSSL OPENSSL_ia32cap(3SSL)
NAME
OPENSSL_ia32cap - finding the IA-32 processor capabilities
SYNOPSIS
unsigned long *OPENSSL_ia32cap_loc(void);
#define OPENSSL_ia32cap (*(OPENSSL_ia32cap_loc()))
DESCRIPTION
Value returned by OPENSSL_ia32cap_loc() is address of a variable containing IA-32 processor capabilities bit vector as it appears in EDX
register after executing CPUID instruction with EAX=1 input value (see Intel Application Note #241618). Naturally it's meaningful on
IA-32[E] platforms only. The variable is normally set up automatically upon toolkit initialization, but can be manipulated afterwards to
modify crypto library behaviour. For the moment of this writing six bits are significant, namely:
1. bit #28 denoting Hyperthreading, which is used to distiguish
cores with shared cache; 2. bit #26 denoting SSE2 support; 3. bit #25 denoting SSE support; 4. bit #23 denoting MMX support; 5. bit #20,
reserved by Intel, is used to choose between RC4 code
pathes; 6. bit #4 denoting presence of Time-Stamp Counter.
For example, clearing bit #26 at run-time disables high-performance SSE2 code present in the crypto library. You might have to do this if
target OpenSSL application is executed on SSE2 capable CPU, but under control of OS which does not support SSE2 extentions. Even though you
can manipulate the value programmatically, you most likely will find it more appropriate to set up an environment variable with the same
name prior starting target application, e.g. on Intel P4 processor 'env OPENSSL_ia32cap=0x12900010 apps/openssl', to achieve same effect
without modifying the application source code. Alternatively you can reconfigure the toolkit with no-sse2 option and recompile.
