writing 0xFF with the dd command


I'm trying to write a 100MB file for example all with 0xFF so in the hex editor it should look like "FF FF FF FF FF FF" etc.

I know you can write a 0x00 with this line:
Code:
dd if=/dev/zero of=myfile bs=1M count=100
But how to do 0xFF or another character?

I want to use the 'dd' command because with the 'bs=1M' argument it is 100 times faster than any other shell command I've seen.
