Interrupt 19h	Bootstrap Loader

(0:0064h) Reads track 0, sector 1 into address 0000h:7C00h, then

transfers control to that address. If no diskette drive

available, transfers to ROM-BASIC Int\18 or displays loader

error message. Causes reboot of disk system if invoked while

running. (no memory test performed).

note 1) This doesn't work on many machines, use

MOV BX,1234 ;No memory test


MOV BX,0 ;Test memory

MOV AX,0040


MOV [0072],BX


2) If location 0040:0072 does not contain the value 1234h, a memory test

will be performed before reading the boot sector
