I decided to try it myself... Booting the AROS floppy disk in PCTask4... so far so good... though somewhat slow :-)
-Edit- Booting using the VGA, Slow ATA settings... something seems to go wrong when jumping out of supervisor mode though :-/
-Edit2- The problem seems to be with PCTasks lack(?) of FPU emualtion...
-Edit3- PCTask doesn't recognise the 040 FPU... :-(
