SGI and IRIX German technology website Heise.de reports that SGI will completely abandon its MIPS processor architecture, including its operating system Irix, in favour of Linux-powered Itanium workstations. SGI used MIPS and Irix in its products for almost 20 years, and with this switch to Intel, yet another major (historically speaking, that is) company abandons its architecture for the more common Intel one.

Did they license most of Irix from SCO as a Unix derivative or is it like Solaris and a BSD derivative? If the former, then they can't open source it, if the latter, then they may just have to remove any closed code they don't own.

Solaris isn't a BSD derivative... that's SunOS (4 and earlier). Solaris is based on AT&T SVR4, which SCO now own. Having to rewrite Solaris to remove SVR4 code is why open-sourcing Solaris took so long.

Do you know this as a fact? The story I collected is different.
"We paid a big, big bag of money a decade ago to get IP rights to do what we wanted to do with Solaris", said Scott McNealy. [ http://news.com.com/Sun,+HP+SCO+probably+wont+touch+us/2100-1016_3-... ]

"We have seen what Sun plans to do with OpenSolaris and we have no problem with it," McBride said. "What they're doing protects our Unix intellectual property rights." [ http://www.eweek.com/article2/0,1759,1785664,00.asp ]

Based on those quotes, it's unreasonable to think Sun had to remove SVR4 code, which SCO owns according to you.

it is much more involved than that...

http://www.levenez.com/unix/history.html#07

Solaris 1 is based on SunOS 4.1

SunOS 4.0 has influences from 4.3BSD (Tahoe)
SunOS 3.2 has influences from UNIX System VR3

therefore Solaris 1 has roots on 4.3BSD and is not based on UNIX System VR4, however as you can see Solaris 2.0 got influenced by UNIX System VR4.

it is not a trivial story...

SCO and Novell are currently disputing who owns Unix. SCO doesn't own much of anything it looks like, based on the wording of the contracts.

Meh, Novell can just over-rule what SCO says and give them the right to do it anyways. Novell still has the final say on what licensees are allowed to do with Unix code.

And what they licensed from "SCO" (SCO is nothing more than a rogue glorified licensing agent on behalf of Novell) probably makes up very little of Irix.

Dude! License IRIX from SCO? Drop back a bit and think this through a couple times and see what other impressions you get.

SCO doesn't own IRIX. No matter whether you mean [the] Santa Cruz Operation, now owned by SUN after changing it's name to Tarantella and switching focus from operating systems to interoperability software a la Citrix, nor by The SCO Group, formerly Caldera, a failed Linux vendor that currently gets a 5% commission from Novell on Unix SysV license sales. IRIX is a trademark of SGI and is their product. They may still license some SysV code. It's hard not to do since things like init scripts or printer script "filters" are all unpublished property of $vendor. Or you could replace the init system scripts with a binary a la Solaris.

The only reason they still exist is because about 7 months before bankruptcy they were able to attract investors by suing IBM for $3 beeeeelyon!

They showed Jay Schulist's clean room version of Berkeley Packet Filter code as one example of proof of their infringement claims.

These guys are clowns who have parlayed hundreds of millions of investor dollars into a failure so abject that it attempts to delay the inevitable with any available option.
