I wrote code for testing the MMU setup under TOS back in April 1999 but didn't get to including it into bootstrap up until today. My main problem was that I was absolutely sure the mapping of FastRAM on AfterBurner040 was 1:1. My fault! In fact, there is a small area reserved at the beginning of FastRAM for TOS ROM copy so there is a small offset between the physical and virtual addresses. As soon as I discovered this it was easy to modify the memptr of bootstrap and so now I am happy to tell you that even with 4 MB of ST-RAM it is possible to boot Woody's 7 MB ramdisk! There is another small issue with the bootstrap but I feel like opening new thread with correct subject would be better. Tired of crossposting I am wondering what list is more appropriate - whether linux-m68k (they have CVS m68kboot) or debian-m68k (they have a separate package atari-bootstrap). Please note that the Sarge's d-i still doesn't boot due to "Kernel panic: Attempted to kill init!" Petr
