Thanks for all the help.
I tried removing the picasso monitor and boot to standard ecs. It now behaves differently, after the whdload splash screen it goes to a gray screen and not back to workbench. Unfortunately it doesn't go further...
Now I know it works on a 3000D, so there is hope. Will try a different version of WHDLoad, the same one that Lost had success and see what happens.
Paul, for me the green screen is because of the NOVBRMOVE command. Do you have that tooltype?
Will try 17.0 and let you know...
Lost do you know you MB rev? Mine are 9-03, with the WD Proto -08 SCSI. The one I'm hoping to install this on has a Sprectrum, Ariandne, 16megs of 60NS ZIPS (turned ramsey wrap, burst, and page off), Buster 11, DMAC 04, RAMSEY 07, 3.1 ROMS and Workbench 3.9 with BB4.
