Glad I looked at this old thread and great to see more BIOS updates. Since my M9A is modded (Post #1 ones) was very easy Flash. Just rename as "creative.rom" and use USB with BIOS FlashBack. Seems the "key" is using a 4GB (or less) USB 2.0.
Fun Fact was that 2301 dsanke modded BIOS did not work with a 9100F but 2603 worked just fine haha
