 This fb driver is only activated at boot time and the settings cannot be 
 changed using fbset.
 
+The graphic modes are NOT in the list which you get if you boot with
+vga=ask and hit return. The mode you wish to use is derived from the
+VESA mode number. Here are those VESA mode numbers:
+
+    | 640x480  800x600  1024x768 1280x1024
+----+-------------------------------------
+256 |  0x101    0x103    0x105    0x107   
+32k |  0x110    0x113    0x116    0x119   
+64k |  0x111    0x114    0x117    0x11A   
+16M |  0x112    0x115    0x118    0x11B   
+
+The video mode number of the Linux kernel is the VESA mode number plus
+0x200.
+ 
+ Linux_kernel_mode_number = VESA_mode_number + 0x200
+
+So the table for the Kernel mode numbers are:
+
+    | 640x480  800x600  1024x768 1280x1024
+----+-------------------------------------
+256 |  0x301    0x303    0x305    0x307   
+32k |  0x310    0x313    0x316    0x319   
+64k |  0x311    0x314    0x317    0x31A   
+16M |  0x312    0x315    0x318    0x31B   
+
+To enable one of those modes you have to specify "vga=ask" in the
+lilo.conf file and rerun LILO. Then you can type in the desired
+mode at the "vga=ask" prompt. For example if you like to use 
+1024x768x256 colors you have to say "305" at this prompt.
+
+For this code use mode 312 so the vga number will be 312.

 You can also try loading a card-specific module as root
 if you know your card's maker.
