When you boot OpenBSD/macppc, your screen goes blank here, root on wd0a (e4d1ce90095ba4d8.a) swap on wd0b dump on wd0b radeondrm0: RV280 [drm] *ERROR* Unable to locate a BIOS ROM ---- screen goes blank ---- radeondrm0: 1024x768, 16bpp My PowerBook G4 (1.5 GHz PowerBook5,4) works well, root on wd0a (7f743336b2c4e92e.a) swap on wd0b dump on wd0b radeondrm0: RV350 [drm] *ERROR* Unable to locate a BIOS ROM radeondrm0: 1280x854, 32bpp I suspect that your "1024x768, 16bpp" mode doesn't work with your eMac's internal display. Your "16bpp" looks strange. Until now, I believed that OpenBSD always defaulted to 32bpp. I don't know if we are missing 16bpp support or have a problem detecting modes (EDID), but the fix would require changes to the kernel's radeondrm code. I don't know the fix. Doing "disable radeondrm" in boot_config(8) might work around the problem. > In addition, I noticed that one step mentioned in the installation > instructions did not happen.

A macppc with ATI Rage 128 or Nvidia graphics would need xf86(4). --George
