on most models), but it can be in other places on systems that don't use a second VIA chip. On the IIfx, NuBus interrupts get routed through OSS to IRQ_AUTO_3. I don't see any cases that use other interrupt levels, but some of the logic is a little harder to follow. It's not an 8390, but it looks like macmace actually uses two levels. The regular interrupt should show up at IRQ_AUTO_3 and the DMA interrupts at IRQ_AUTO_4. Most Macs only use 4 for serial, but this is an exception. Brad Boyer f...@allandria.com

so shouldn't it be possible to only run this code when the appropriate entries are present in the right data structures? I didn't look at a lot of the other serial drivers, but some other mac drivers have recently been updated to no longer have MACH_IS_MAC checks due to being converted to platform drivers.

believe that the user-space programs should need to know as little as possible about the hardware, and it would be nice to abstract that away from the end user as well. We've moved toward commonality and standarization in other areas, and I think we should here as well. Brad Boyer
