This kernel does not seem to support either of my monitors, so I'm a bit
stuck here. The boot loader works fine, but when the kernel starts
everything goes fuzzy, and the monitor looses sync.

I have set up my NetBSD/sparc 1.5 as a DHCP and boot server for the Risc
PC, and modified the BtNetBSD application as outlined in one of the
earlier mails in this thread, and the kernel boots, but then the screen
just will not synchronize.

I have changed the config to:
Run <BtNetBSD$Dir>.BtNetBSD <BtNetBSD$Dir>.^.kernels.netbsd maxproc=64 nofpa  

And, set the:
*WimpMode X640 Y480 C256

Or:
*WimpMode X1280 Y1024 C256

As my monitors support these, but to no avail.

I have attached my two special monitor files in case that can help you
figure out why it doesn't work on my monitors.

CTRL-T seems to drop me into the debugger, and running reboot from there
does indeed do a reboot.

I can, of course, hook up a third monitor, but that should not be
necessary, if you ask me.

I have been trying to boot from the network, and it is able to get a
lease from the DHCP server after I enter ne0 blindly and press enter
three times, but something does not work correctly, and it dies.

Since I am unable to see what happens it is very difficult for me to
track this down.

Could someone please help me out here?

TIA!
