+# console
+You can get full console resolution on an Intel 945-series graphics adapter with 915resolution. Find some spare mode like 640x480:
+
+    % sudo ./915resolution -l
+    Intel 800/900 Series VBIOS Hack : version 0.5.3
+
+    Chipset: 915GM
+    BIOS: TYPE 1
+    Mode Table Offset: $C0000 + $269
+    Mode Table Entries: 36
+    ...
+    Mode 41 : 640x480, 16 bits/pixel
+    ...
+ 
+Set it to 1024x600 for example:
+
+    % sudo ./915resolution 41 1024 600
+
+Then load vesa:
+
+    % kldload vesa
+
+And use vidcontrol:
+
+    % vidcontrol -i mode|grep 1024
