Kickstart in fast using BlizKick with the usual patches to get exec in fast etc

8GB SanDisk Ultra SD on the older type of SD-adapter (which doesn't have to be fixed to avoid HD-led constant on issues)

Notes: It seems the DiskSpeed usage pattern causes the SD card performance to detoriate completely - see the create and write speed.
       A completely sequential write, like an 10MB copy from ram: to the drive completes in less than 7 seconds - over 1.4MB/Sec. Very
       slow by A1200 IDE standards, but nevertheless not abysmal like these results.
       Perhaps the hammering of small accesses by diskspeed in the beginning of the test causes some sort of garbage collection issues
       for the SD card.
