Have Seen the SPARC machine (Really an Un believable Performance )

SPARC machine which has super concept called Ok Prompt

with out booting to Os we can able to control some of Admin activity…which really admire me……

Ok prompt not available in Intel X86 machine…

while working in SPARC Machine an special type of keyboard with extra 16 keys …Specially designed

Stop + A    ——->which enter into ok prompt with Single User Mode…….

Mostly the key disable while running in SPARC machine For Security reasons ….
