SunOS 5.6 has support for large files but 5.7 is indeed where full 64 bit support starts.
According to Posix standards, with which Sun claims compliance, you run "uname -s" to get to get the name of the OS and you run "uname -r" to get the release.
As near as I can figure, it goes like this: In the beginning there was SunOS and it was based on BSD. But SunOS 5.0 was a major rewrite and at this point SunOS was now based on System VR4. Apparently some marketing droid came along and christened the result "Solaris 2.0". But the kernel programmers ignored him and continue to call the OS "SunOS 5.0".
The kernel programmers continue to use their naming convention and named various releases stuff like "SunOS 5.6" which the marketing droid called "Solaris 2.6".
But with SunOS 5.7, the marketing droid decided to call the OS "Solaris 7". I'm betting that he switches to Roman numerals pretty soon.
So it looks to me like Sun is unable to reach a unified conclusion as to what to call their OS. I wish they would hold a hot dog eating contest or something to settle this. In the meantime you have two choices.

Hi all,
I'm looking to cover a corner case for an upcoming test cycle. Is there a way to boot a RedHat Advanced Server 4 (update 3) installed on a Power PC machine to use a 32 bit kernel? This would be similar to what is done here -> https://www.unix.com/aix/26204-aix-platform.html

arch(1) User Commands arch(1)
NAME
arch - display the architecture of the current host
SYNOPSIS
arch [-k | archname]
DESCRIPTION
The arch utility displays the application architecture of the current host system. Due to extensive historical use of this command without
any options, all SunOS 5.x SPARC based systems will return "sun4" as their application architecture. Use of this command is discouraged.
See NOTES section below.
Systems can be broadly classified by their architectures, which define what executables will run on which machines. A distinction can be
made between kernel architecture and application architecture (or, commonly, just "architecture"). Machines that run different kernels due
to underlying hardware differences may be able to run the same application programs.
OPTIONS
-k Displays the kernel architecture, such as sun4u. This defines which specific SunOS kernel will run on the machine, and has impli-
cations only for programs that depend on the kernel explicitly (for example, ps(1)).
OPERANDS
The following operand is supported:
archname Use archname to determine whether the application binaries for this application architecture can run on the current host
system. The archname must be a valid application architecture, such as sun4, i86pc, and so forth.
If application binaries for archname can run on the current host system, TRUE (0) is returned. Otherwise, FALSE (1) is
returned.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.

NOTES
This command is provided for compatibility with previous releases and its use is discouraged. Instead, the uname command is recommended.
See uname(1) for usage information.
