PXE network boot is available only for devices that implement the Intel Preboot Execution Environment specification. To determine if your system supports PXE network boot, see your hardware manufacturer's documentation.
In the Solaris 10 3/05 and earlier releases, the Solaris boot diskette is still available for systems that do not support PXE. The boot diskette image is available on the Solaris 10 Software for x86 Platforms - 2 CD. The Solaris boot diskette is not available in the Solaris 10 2/06 release.
