Mark, Please post the file: SYS$SPECIFIC:[SYSEXE]MODPARAMS.DAT Then $ DEFINE/USER SYS$OUTPUT MEMORY.TMP $ SHOW MEM/FILE/FULL/ALL/PAGE Then $ DEFINE/USER/SYS$OUTPUT DECW.TMP $ SHOW LOG DECW$* Post the files MEMORY.TMP and DECW.TMP or send the whole thing to me directly and I'll see what I can come up with. If you have IP or DECnet running I can come in and look directly.

Sorry about the slow response, I have been doing a lot of RTFM and trying to get used to the system. I also bought a HP zx6000 Itanium workstation, but that's an aside for later ;) The contents of the DECW$PRIVATE_SERVER-SETUP.COM file: $ set verify $ decw$server_page_file== 160000 $ decw$xsize_in_pixels == 1280 $ decw$ysize_in_pixels == 1024 $ define/exec/system/nolog decw$server_pixel_depth 24 $ define/exec/system/nolog decw$server_refresh_rate 75 $ set noverify I got back to this eventually today. Still no luck. If I use your config as you printed it it still crashes the whole machine dead at boot and I have to enter a minimal boot and pull the file out to get any luck booting again. Same as before. I don't get what's goin on. :( -- Mark Benson My Blog: <http://markbenson.org/blog> Follow me on Twitter: http://twitter.com/mdbenson "Never send a human to do a machine's job..."
