Solaris x86: An free, open source Unix

Since Solaris x86 doesn’t support as much esoteric hardware as the Linux kernel does, and since Solaris’s driver support is nowhere near as comprehensive, begin by checking Sun’s Hardware Compatability List (HCL) to see if your system components are supported. The Solaris 9 HCL can be found at http://www.sun.com/bigadmin/hcl/data/sol/, and the Solaris 10 HCL can be found at http://www.sun.com/bigadmin/hcl/data/sx/. You may need to check both lists, as Solaris 10 pretty much supports everything listed for Solaris 9.
