-Unnamed Mindlapse DOS demo for Pentium 133
-------------------------------------------
-The demo requires VESA Bios Extensions (VBE) 2.0. If your graphics card doesn't
-support VBE 2.0 or greater, then make sure to load the `univbe` TSR first.
+Unnamed Mindlapse DOS demo for Pentium-era PCs
+----------------------------------------------
+The demo uses VBE 320x240 16bpp. Some VBE implementations do not expose
+double-scan video modes (240 lines), but can be made to work with a third-party
+VBE TSR like `univbe` or `s3vbe`. Linear framebuffer (VBE 2.0) support is
+recommended, but not necessary. The demo will fallback to VBE 1.2 banked modes
+if LFB modes are not available.

 Building on DOS with Watcom
 ---------------------------
-NOTE: Don't. Watcom produces significantly worse code than GCC, and at the
-moment watcom-compiled version of the demo crashes on 3D scenes for some reason
-which I need to investigate at some point. Suspect either inline assembly with
-missing "modify" part, or more likely some FPU optimization which fucks up the
-clipper.
-
 Make sure you have Watcom or OpenWatcom installed, and the appropriate env-vars
 set (the watcom installer automatically adds them to autoexec.bat by default).
