LPC2104: which pin selects bootloader?

LPC2104: which pin selects bootloader?

Leon's schematic shows P0.14/EINT1.

The Olimex '2106 schematic shows P0.14/EINT1.

Page 177 of the Philips LPC2106/205/2104 UM (sep 17 2003) claims that P0.14
determines whether the chip boots to the bootloader or user code.

BUT, page 37 of the very same user's manual gives the boot select function
to pin /EINT0. (Which is shared with P0.16!)

So, what's the real story here?  I didn't notice this mentioned in the FAQ,
so maybe I'm the first to be confused by this.
