Sun Hardware disgnostics?

[shn at think.com]

Is there any software which can be booted from tape or disk which will
*really* test a Sun?  I want to include cache, memory, FPU, CPU and
perpheral tests.  Obviously this would run in a stand-alone mode (ie not
under Unix/SunOS) and it would probably be hardware specifiy.  Does Sun or
any other third party vendor supply such a product?  I am sure Sun has one
internally used as a final qualification before shipping.  Do they sell
it?

Thanks
