I lowered the monitor depth to black and white in the control panel( Actually went into the options and changed the memory allocation. I think there is a problem with the way the kernel allocates memory for the video. I got the machine too boot after this, but there is still crashes often - vmfaults. I have 8meg also and a similar setup. I think if someone with a more stable setup that could actually compile the whole kernel without crashes( I expect it would take about 15 crashes before I could recompile the whole kernel - if it would even work at all) with the following change at bootup: Video address = 0xfbb08000 Int Video starts at 0xfbb08000 Length = 0x10000 (65536) Bytes I am guessing that if you change the lenght to 128,000 bytes or 0x20000 it might work for us with a mac IIci. All the crashes seem to corrupt the very bottom of the screen like just the first char on the lower left. With black & white 640 x 480 one would figure it would take 38400 bytes of ram. If somehow though twice that was needed for some reason, that would be right over 65k and perhaps then when memory got tight it would collide or something causing the crash???? I'm just speculating as you can tell. Anyway, if someone could go through the bother of makeing a new kernel for the mac IIci that allocats 0x20000 there I'd give it a go. I have set up a directory at freedom.wit.com/unix/mac/netbsd/uploads that anyone that might feel so inclined could put it there and I'll make it available to the other interested parties then. jcarr@wit.org In article <aaronv-1003961259090001@isdn6-205.dnai.com>, aaronv@dnai.com (Aaron Vinson) wrote: > Hi, I've recently been trying to get NetBSD 1.1 to run on a IIci with 8mg > of RAM.
