Dual boot on iMac 8,1

Update: #18174 (MacBook Late 2007, Intel GMA X3100 not working) – Haiku (haiku-os.org)
See: Boot Loader (haiku-os.org)

Usually for custom boots:

Provide/edit:

  • ~/config/settings/kernel/drivers/kernel
    • fail_safe_video_mode true (remove #)

Everything else relies on what you’ll see in on-screen debugging.

Check with core devs on IRC and Haiku on Mac support.
