Sure, this reboots all right, if you put a boot floppy in drive A:.
Don't count on it rebooting from your hard disk.  Int 19h all by itself
doesn't always cut it.  This method also doesn't clean up any BIOS
variables that DOS and/or any BIOS extension ROMs might have diddled with
during the previous reboot.  The surest way to reboot, I think, is still
to set 40:72 to 1234 (warmboot flag, causes some of the power-up
self-test code to be skipped) and do a far jump to FFFF:0000.
