ill probably get solaris too work on the sun microsystems netra 1u sparc im getting tomorrow otherwise i will be poed if solaris doesnt work on sun server
The Sun Netra X1 is almost identical to the Sun Fire v100 I have. In fact, I ordered a Sun Netra X1 on eBay but I received a Sun Fire v100 instead, the only difference was that the Sun Fire v100 has a CD drive. To install Solaris 10 on it, you will need to use the serial port (LOM - Lights Out Management). For this, you need an rj45 to db9 adapter.
A good link you might want to check: HOWTO: Installing Debian Linux on a SUN Netra X1/Fire V100
You can follow the same instructions in order to be able to start your Installation, the only difference being you don't put a Linux CD in your CD-ROM drive.
As said in the article, not a lot of CD-ROM drives work with the Sun Netra X1 if you try to open it and connect one, so you might as well try a network installation. Google "Jumpstart Solaris Installation" for that.
Be reassured, Solaris
does work on Sun Servers, but not OpenSolaris (not yet, but I've heard the support for SPARC would be limited to processors more recent than the UltraSPARC IIe when OpenSolaris for SPARC will come out).
