Early A3ks came with a 'Superkickstart', that loaded a Kickstart image from HDD prior to booting. You could choose whether you wanted 1.3 or 2.x. The Superkickstart floppy disk held both a 1.3 and a 2.04.
The built-in ROM actually is a 1.4 - you can see it if you hit the (invisible) close gadget of the selection window (accessible when holding both mouse buttons on power up). :-)
