As I pointed out previously the Sun cards and the Mac cards dot -not- have
the same firmware. This I can confirm 100%

Good luck. See comments above and below.

Most PC edition Radeon 7K boards cannot be flashed with Sun or Mac firmware
without replacing the flash chip with a larger capacity one. The size needed
escapes my tired brane right now.

I personally have successfully flashed a Sun OEM Radeon 7K to Mac. I have
also successfully flashed a PC edition R7K to Mac firmware after the flash
chip was replaced.

Great job for a masochist.

Since PC cards are generally fairly dumb devices they didn't need to spend
the extra money on larger flash. Also I am sure the economies of scale come
into play for pricing here as it is likely ATI made 10 times more PC cards
than Mac cards.

Although I will confess I would not be shocked if it was a profit measure
taken by ATI.

What me a cynic??? ;-)
