This makes sense.
The ROM read physically limited to 3.5 MB/sec on classic
To fastmem on a CPU card the read speed would be over a magnitude faster.
This means for performance reasons we want to put the Kick in fastmem anyway.

So A1000 design to have a small bootrom and the KICK then placed into WOM-Ram is ideally for this.

Good sense or bad sense? The ROM speed is only limited to 3.5MB/sec on 68000 base machines. The 68020+ base machines can manage 12-20 MB/sec ROM speeds. This is much faster than most IDE or SCSI controllers could seek and load a 512KB (or even a 1MB Kickstart). Loading individual libraries and modules is even slower.

The amount of extra code and data files in OS3.9 BB1-4 already adds a significant boot delay without including any 3rd party stuff. If you want a faster Kickstart for 68000 base machines than why not remap it in to 32 bit Fast RAM?
