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
Please note that the Sarge's d-i still doesn't boot due to "Kernel
panic: Attempted to kill init!"
