Not necessarily. I have a test box that just crashes if the graphics card is
not posted.

You may try to use 's2ram --force --vbe_post --vbe_mode', if you haven't tried
that already.

Still, if the card is a 7300 or higher, that need not work (at present we don't
know what magic is required to make these cards work).

Greetings,
Rafael
