Hardware needed to Program Atmel AT89C51 using Flip

Does this chip come pre-programmed with a bootloader?  It seems from
the datasheet that all thats needed to program it (in-system) is the
use of Atmel's FLIP software, and no mention of any hardware
requirements (PSEN, etc).

Is it that easy?

Which specific Atmel AT89C51 variant ?

The AT89C51ED2 is quite clear in the data, on the Loader options, and
Fuse/Pin force options ?

At least some have a bootloader. Then you only need FLIP and and RS232 to
TTL interface (maybe already on your board). To enter the bootloader, you
need to pull PSEN to the right level when reset is deactivated, so a switch
controlling PSEN and a reset button are nice to have. And make sure you set
the BLJB to the correct value in FLIP or your application won't start.
