It's probably a well known technique when debugging PM programs to use two monitors: one to display the PM app, the other exclusively displaying codeview. This prevents the nasty double page flick between codeview's screen and the desktop when you step, set breaks, etc. Although this environment is easy to set up on a PC, I have so far had zero success setting it up on a PS/2. My config is a PS/2, an 8514/A adapter card, and two monitors - one plugged into the 8514/A and the other into the PS/2's standard onboard VGA connector. IBM claim that using codeview with 2 monitors is impossible. From my foolings around, this may indeed be true (for PS/2's, mind you). Anyone ever had success in this area? nico -- nico@micrognosis.los-gatos.ca.us Vique's Law: "A man without religion is like a fish without a bicycle."

I run this configuration. The 8514/a and display run BGA mode, the 8513 monitor runs full screen. The trick was to get your config.sys and display.dll set up properly. Believe me, it is a nightmare if you don't get it right during OS/2 install. (Unix does much cleaner with good old /etc/ttys thank you). Here is my config.sys REM * 8514/A w/additional VGA display SET VIDEO_DEVICES=VIO_IBMVGA,VIO_IBM8514A SET VIO_IBMVGA=DEVICE(BVHVGA) SET VIO_IBM8514A=DEVICE(BVH8514A) I have in my c:\os2\dll has the following display dlls. I think these are all you need, but be careful, I may not have the complete list... ---A- Dec 3 19:16:48 1990 7898 8192 bvh8514a.dll ---A- Dec 14 12:26:54 1990 32746 32768 bvhvga.dll ---A- Dec 3 18:56:32 1990 283856 284672 display.dll ---A- Dec 3 19:08:28 1990 8116 8192 bvhinit.dll ---A- Nov 3 11:45:40 1990 6553 8192 bvhwndw.dll When I bring up CodeView 3.0, it displays on the VGA monitor. Currently OS/2 PM suffers from the fact that it can't handle multiple displays like X does, so you get the unique *feature* of watching one tube's display Freeze while the other has focus. When the VGA has focus, you have to use CTRL+ESC or terminate the full screen program to switch back to the PM monitor. Hope this helps,
