does anybody know how 2 use this code?

#single BOOT0x00101420 0x340800FF0x00185E00 0x0E2404FEdoes anybody know how 2 choose who u wanna boot?

if im not mistaken the rightfully code is
#single BOOT
0x00101420 0x340800FF
0x00185E00 0x0E2404FE

But sorry i know nothing about boots, as i dont use them, inless i have two.

It's not a single boot it will still boot everyone.
