Bootsie, a utility by Stefan Krey that writes a boot sector to a floppy disk to perform many rather nifty system init functions. These will be useful for Atari owners with a hard drive or those fortunate to own a MSTE, TT or Falcon.
By default, my Mega STe boots up in an 8MHz "compatibility mode" which is great for gaming but pretty lame for everything else. After all, the entire boot process from start to end will be a lot slower than it could be at 16MHz. Enter Bootsie that can set the processor speed to steroid mode and it will also do lots more cool stuff, such as CPU caching, activate the Blitter chip, 60Hz display, and much more. What a fantastic utility that helps make a computer as zippy as is possible. Download it right now from Atari ST Essential Software List.
