Well, here [PDF FILE] is a nice installation guide and it says that Solaris 10 can be installed with just 256 MB of RAM. I can say that too because I've installed it myself. But it will really test your patience.
Buddy it's impossible for the latest version
coz i have tried it when i used to have 256 Mb
and the minimum requirements is 512 MB +
U must have used old version
and Solaris is NOT a good OS for workstation too..
I have seen and heard that several data center's and workstations use UBUNTU,Slackware etc., and very less people use this OS..
This OS is very resource hog and servers,datacenter's and workstations require light and less resource hog OS
@Gautham:Where did u saw Solaris in action..?
