- I can't help you on this one. The NetBSD generic kernel
- recognized and used my Picasso II without problems.
- Is it possible your monitor does not support the display
- rate the NetBSD kernel sets the monitor at? It is a
- pretty low frequency, so I'd hope that's not the case.

- I had quite a bit of difficulty setting the modes also,
- took quite a bit of experimenting. I now have the
- following modes defined for my Picasso (grfconfig /dev/grf3
- can be used to display this information):
- 1: 1024x800x8 52.1kHz @ 60Hz NI
- 2: 800x600x8 62.9kHz @ 96Hz NI
- 3: 640x480x8 42.8kHz @ 82Hz NI
- 4: 320x320x8 39.8kHz @ 117Hz NI
- 5: 1152x900x8 55.9kHz @ 58Hz NI
- 6: 1024x600x8 32.1kHz @ 49Hz NI
- 7: 1024x800x8 60.7kHz @ 70Hz NI
- 8: 1024x800x8 61.0kHz @ 71Hz NI
- Console: 640x480 (80x60) 42.8kHz @ 82Hz NI
-
- I've set up a file /etc/grf.conf which is grfconfig'd
- from the rc file at bootup (I added this). It contains
- the following lines (no preceeding tab on each line):
- c 35000000 640 480 8 640 686 740 770 820 481 490 498 522 522

- I think your main problem is that your X direction is a bit hosed
- up in the config line you gave. Also, your console is configured
- with the 'c' mode, instead of number '1'.
-
- p.s. This is a crappy monitor I have, but it seems to handle
- a very fast refresh rate. Please do not just try all the
- modes above unless you are sure your monitor can handle
- them. I'm sure you've seen the warnings - a non-syncable
- frequency can destroy your monitor.
-
- p.p.s. While testing, it may be best to place a working mode
- immediately following the one you are testing - in case
- you hit something unsyncable, it will only then be there
- for a second or two. ie (if testing 35Mhz pixel clock):
- c 35000000 640 480 8 640 686 740 770 820 481 490 498 522 522
- c 25200000 640 480 8 640 686 740 770 820 481 490 498 522 522
