Hi Sekher,
we are using Solaris OS on two different Hardware Platforms
1. x86 (Intel Compatible Hardware)
2. x64 (SPARC Hardware (Scalable Processor Architecture), Which is developed SUN (Stanford University Network) team).
for x86 machines we are using GRUB (Grand Unified Boot Loader) Boot loader program. for x64 machines we are using ufsboot program.
Basically we are using GRUB boot loader in Linux OS.
