Cc: mrao.cam.ac.uk!mjo AT cs DOT unm DOT edu, vuse.vanderbilt.edu!csaba AT cs DOT unm DOT edu, Cotton Seed , Mat Hostetter One more update on my driver problem. It turns out that the problem goes away if I restart my machine with the restart button. NEXTSTEP must be doing something to the card that prevents it from going into 640 x 480 ; 8 bits per-pixel mode, at least with the initialization in the built-in VESA driver, the vesa_s3 driver, and a couple of VESA testers I tried from the net. So as long as I do a hard-restart, or never start NEXTSTEP, the demo version of Executor with color mods in it starts OK with the built in VESA driver. It does have a few glitches, and is still in the embryonic stage w.r.t. color, but it's cool to see Lemmings for the Mac start up in color. However, if I try to use the vesa_s3 driver that Csaba and Matin Oldfield suggested, Executor dies with an illegal instruction error down in a memory location that the go32 debugger reveals to be the legitimate starting address of one of our routines, so there's some sort of smashage. The smashage is quite possibly due to our funky memory layout, since we start our text segment at location 0. This hasn't hurt us so far, but we're looking into it. The quick response that I've gotten to this question has been very handy. Thanks. --Cliff ctm AT ardi DOT com Begin forwarded message: Date: Sat, 18 Jun 1994 14:54:41 +0600 From: mimbres!vuse.vanderbilt.edu!csaba (Csaba A.

Also, the GO32 1.11 built-in driver may support it using 256 colors and non-accelerated VGA-style memory access. Csaba Biegl csaba AT vuse DOT vanderbilt DOT edu
