Here is the VGA resolution and colour dept chart , this may help you.
256 colours is 8 bits , the vga= can accept parameters in either hexadecimal 
or decimal , 0f00 = 3840 in decimal , 0f07 = 3847.

From memory , colour charts and possibly vga charts cycle through the 
colour/resolution table in multiples of set values and 0f00/0f07 are one of 
the resolutions that is acceptable to the system because it has a value 
somewhere when cycling through the 800x600 colour /resolution table.
