SPARCstation 20 model HS11: Solaris 1.1.2 and Solaris 2.4 HW 11/94 or
later
SPARCstation 20 model 712: Solaris 2.3 HW 8/94 or later.
SPARCstation 4: Solaris 1.1.2 and Solaris 2.4 HW 11/94 or later
SPARCserver 1000 and SPARCcenter 2000 : Solaris 2.2 or later and
should really use at least 2.3.
Some notes:
Sun4 machines (4/1xx, 4/2xx, 4/3xx, and 4/4xx) will not be supported
after Solaris2.4.
The audio device on the SS5/SS20 has does not work under Solaris 1.1.1b
without installing the ms2 patch found on the 1.1.1B CDROM or get
the current Audio Patch from Sun. You will need patches to get the
Audio to work properly under Solaris2.3 as well.
Also, the SX Graphics card is only supported under Solaris2.3 HW 8/94
or later. The Card will not run work under SunOS 4.1.x and unless
some one other than Sun writes a driver it will never work.
If you are running Solaris 1.x and newer versions of the SuperSPARC CPU
(rev 3.5 and higher) require Solaris 1.1.1B. See question 79 for
the procedure used for determining SuperSPARC revision.
When installing any compatable version of SunOS 4.1.x on any
of the following: SPARCstation 5, LX, Classic, or SPARC 20 you
must buy a RTU because these machines came with RTU's for
Solaris2.x only.
SunOS 4.1.3 has been reported to run on the SPARCstation 10 model
412/512 and the 600 model 412/512, but this configuration is not
supported by Sun. Anyone who tries this is on their own. The
(unofficial) word from inside Sun about whether or not it actually
works is as follows:
Little testing of the SuperSPARC MP configurations under 4.1.3
have been done by Sun. What little was done showed that under
heavy loads the system was prone to crash (What it really did
was hang, so badly that even an L1-A would not work).
...
We suspect, but do not know, that as the SuperSPARC chips get
faster that the problems will manifest themselves more quickly.
Solaris 2.0 runs only on SS1,1+,2,SLC,IPC,ELC,IPX.
Solaris 2.1 and later runs on all Sun4s and SPARCstations, but the
FPU's on the 4/100 and 4/200 series machines are disabled and will
be under all versions of Solaris2.x.
Not all peripherals supported under SunOS 4.x are supported under SunOS
5.x. Check with Sun or the peripheral manufacturer. Most of the
the non-supported cards under SunOS 5.x are VME or Multi Bus based.
Explanatory note:
In general, Solaris = SunOS + OpenWindows.
Solaris 1.0 = SunOS 4.1.1 + OpenWindows 2.0
Solaris 1.0.1 = SunOS 4.1.2 + OpenWindows 2.0
Solaris 1.1 = SunOS 4.1.3 + OpenWindows 3.0
Solaris 1.1.1 = SunOS 4.1.3_U1 + OpenWindows 3.0_U1
Solaris 1.1.2 = SunOS 4.1.4 + OpenWindows 3.414
Solaris 2.0 = SunOS 5.0 + OpenWindows 3.0.1
Solaris 2.1 = SunOS 5.1 + OpenWindows 3.1
Solaris 2.2 = SunOS 5.2 + OpenWindows 3.2
Solaris 2.3 = SunOS 5.3 + OpenWindows 3.3
Solaris 2.4 = SunOS 5.4 + OpenWindows 3.4
Open Windows versions before 3.3 used the X11/NeWS server
all versions since use a MIT style server with Display
Postscript Extensions.
