No, it's using the eval.

With the attitude of many today "I want the best software money can buy, but I do not want to pay for it" Keil had to come up with a scheme to make the free eval version incapable of being used as a free tool for programming limited meomory size derivatives.
One method was to make the eval incapable of locating C code below 400h. To make the eval usable they made the eval linker include a small code that at the interrupt location stored jumps to the location+400h

so in 00bh they store a ljmp 040bh.

So, the hardware is the same, just "invisible to the user" the interrupt locations has changed.
