Applications installing themselves here should expect parameters to be located on the stack as they would be for the actual function call beginning at 4(sp). If the installed process services the call it should RTS, othemise, leaving the stack intact, should JMP through the old vector value. 0x0000047A LONG RAM hd'y_boot: This vector is JSR'ed through to boot from the hard disk. A value of0 here indicates that no hard disk is attached. If the installed process services the call itshould RTS, otherwise, leaving the stack intact, should JMP through the old vector value. 0x0000047 E LONG RAM hd'y_mediach: This vector is used when Mediach() is called.
