NetBSD doesn boot on my IIsi with a PDS/NuBus video card; it hangs while setting the video address. Whats wrong?
In the words of Allen Briggs (briggs@macbsd.com): Your problem is that you’re not using internal video. The IIsi only has 1MB soldered on the motherboard in bank A and the memory map looks different depending on whether or not the video is enabled. NetBSD does not correctly handle the case where the kernel does not fit into the first chunk of physical RAM. With internal video enabled, the part of bank A not used for the display is mapped to follow bank B and bank B is mapped to 0x0. With internal video disabled, bank A is at 0x0 and bank B is mapped to follow bank A (at 1MB). The IIci is the same, but most people have more than 1MB in bank A of their IIci so it’s not a problem. You can work around this by either attaching a display to the internal video port, or putting a display adapter (or a paper clip in the right place) that makes the circuitry think that there’s a monitor attached. For more information on this solution, see the Q&A below on booting without a monitor .
