Having received a shiny new Sun x4150 to be used as an exchange server, I came across a few interesting details about it.
1. It comes in lots and lots of boxes and must be assembled.
2. It's nice and easy to work in as its so tidy and well organised.
3. It doesn't come with a CD/DVD Drive by default so pull out your USB drives or just order one from the factory.
As it doesn't have a floppy drive it's a bit problematic installing the drivers for the LSI Logic RAID Card, I had to remaster the windows 2003 64bit CD in order to slipstream the drivers onto it for textmode setup.
Firstly download nLite, its a great tool for doing unattended installations as well as integrating stuff into a new windows install CD
Tell it to rip the windows install from the CD Drive or do it yourself and tell it where the folders are.
On the next screen, pick the drivers button and the bootable ISO option. You can have a play about with the rest but its up to yourself.
Change out your Windows CD for the "SunFire Tools and Drivers CD" that came with your server or download it from sun.com.
On the drivers screen, tell it to import the Multiple Driver select, then pick the cd:/drivers/windows directory (or similar). Then select the drivers that have 64 bit in them, but don't bother with the drivers with RIS in their path.
Hit next and then on the last screen hit Make ISO.
And thats you, burn it out and you are laughing
Apparently there is a tool on the sun disk that does this (or similar) but I didn't have access to a Solaris or Red Hat box to do it.
This worked for me but as always YMMV
