If this Diamond card is a "PC" card (a card with PC VGA BIOS and not "mac" OpenFirmware ROM), then you cannot use this in your Mac. Your firmware will not know how to enable the card so no matter what XFree86 does, it will fail to initialize the card because it was never POST(ed). The Mac does not support ISA memory space so using int10-style soft-booting will not work. The only method I can see to bring up a PC card on a Mac (though I have not yet tried this) is to use a PC and dump a VGA BIOS image and then emulate that image on the Mac (hacking it into int10 perhaps, which will use x86emu).
However, if for some reason your Diamond card does indeed have an OF rom and will powerup, you will just need to add support for your ramdac (which should be trivial as most all of the IBMRGB 52x's are the same except the 528), and then I'll add the proper endian register bits to the driver. ani On Sun, 18 Aug 2002, Thomas Geenen wrote: > hi all > i have a diamond stealth 64 vram with an IBM RGB526CF ramdac chip > i try to run this on an ppc oldworld g3 with xfree4.2.0 > xfree4.2.0 status pages says > > Support (accelerated) for the 964 (revisions 0 and 1), 968, Trio32, Trio64, > Trio64, Trio64V+, Trio64UV+, Aurora64V+, Trio64V2, and PLATO/PX is provided > by the "s3" driver (however, only models using the IBM RGB 524, Texas > Instruments 3025, or an internal TrioDAC RAMDAC chip are supported).
