Momentan ist das Problem die neuen Revisionen der jetzt käuflichen PC-Karten. Wenn jemand ein fertiges ROM für eine spezielle Revision der Karte ins Netz stellen will, muss er die Karte besitzen, das PC-Rom auslesen, mit den Shell-befehlen mit dem EFI-Teil zusammenfügen und dann kann man dieses Rom zurückflashen. Es wird dann mit der Kartenrevision funktionieren. Ich habe eine Sapphire, mit der Limitation auf einen DFI-Port und eine XFX bei der beide funtionieren. Da der Hype jetzt etwas abgeflacht ist und fast jeder so eine laufende Karte hat und die alten Revisionen schwer zu kriegen sind, bleibt nur trial und error.
Ich hätte auch keinen Bock fünf Karten zu kaufen um dann zu sehen, dass die oder die geht oder nicht.
Der Thread im Appleinsiderforum eklärt es anhand der XFX so:
Basically we got 4870 late in game. While it was new to us, the board manufacturers were already playing musical components as they tried to find ways to cut retail cost without hurting bottom line. They finally have changed the XFX boards enough that we need to re-write the official XFX 4870 1 Gig ROM with a "ZWXX" version.
I am NOT going to write it for you, but I will tell you how...and this will apply to any card that comes in future.
Get the XFX Rihldinger ROM. Creat an XFX ROM using the Pipolomo42 method. Use the compare function of a hexedittor to see where rihldinger had to make adjustments to the ROM to get everything to fit in proper place.
Now follow his lead and do same thing with whatever ROM came on your ZWXX card and the Mac EFI ROM. You will likely have to think about what you are doing.
Or beg Rihldinger to work his magic again on the new cheaper 4870 ZWXX boards. Somewhere he explained what he did...maybe search his posts.
Be aware that the new board uses a simpler 2 wire fan. It may not cool properly as the Mac drivers may still be looking for the bigger, different 4 wire unit on OEM and the previously flashed cards. We have same problem flashing a 9800GT with an 8800GT ROM...the fans either run 100% or 0% in many cases due to changes in heat sensor/fan control circuits.
If there is any possible way to find a ZHXX series XFX 4870, I would do that. They are nearly gone from retail channels but some still lurk in corners.
Ansonsten eine 4890 mit Injektor (reine Software) benutzen....
