Solution

.model small
.stack 100h
.code
main proc
MVI BH,3 // Moves data into bh register
MVI BL,0 // Moves data into bl register
MVI AH,2 // Moves data into AH register
loop1:
CMP BH,0
JE END1
MVI BL,0
loop2:
CMP BL,BH // Compare BL register and BH register
JAE END2
MOV DL, \'*\' // Moves * into DL register
INT 21H
INC BL // Increment BL register
JMP loop2 // jump to loop2
End2:
MVI DL,10 //Move 10 into register DL
INT 21H
MVI DL,13 // Move 13 into DL register
INT 21H
DEC BH
JMP loop1
End1:
MOV AH,4CH
INT 21H
