     4Usually the easiest way is to check the file size (in kB) then round it down to the next power of 2. Examples are 128, 256, 512, 1024, 2048, 4096. The rounded down number is the destination file size. Then you run (Linux/*BSD/Solaris/...)

     10bs specifies the destination size, bios.wph is the original file and bios.bin is the .bin file you want. The example above is for a .wph file slightly larger than 1024kB. For a .wph file slightly larger than 512kB, you have to use bs=512k instead. You can probably guess how to handle .wph files with a size slightly larger than 2048kB.
