Here's the easy way to get 458K archive memory.  For real!  (I tested it
personally)

Download the included test.9xz to a freshly reset TI-89 or TI-92+.
Run the program by typing test() and press enter.

Thats it!

For those of you who want to know how it's done, take a look at this source
code:

    include "tios.h"

    xdef _main
    xdef _nostub

_main:
    move.l #$590000,-(a7)
    ROM_CALL $16b ;Call to erase ROM sector
    add.l #4,a7
    move.l #2,-(a7)
    move.l #$590000,-(a7)
    pea.l buf(pc)
    ROM_CALL $171 ;Call to write to ROM
    add.l #12,a7
    rts

buf dc.b $ff,$fe

    end

test.9xz
