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
-or-
MOV BX,0 ;Test memory
MOV AX,0040
MOV DS,AX
MOV [0072],BX
JMP FFFF:0000
2) If location 0040:0072 does not contain the value 1234h, a memory test
will be performed before reading the boot sector
