Unfortunately not. I tried to add env-arc:mmu-configuration file containing "SetCacheMode from 0x00000000 size 0x01000000 cacheinhibit" which should disable caches from lowest 16M but it still hangs.
I guess this only affects data caching, not instruction caching.

Blizzard 1260 nearly fully working!
Blizzard 1260 nearly fully working!
I found a solution, it is quite ugly hack but it does work, 68060.library works, FPU works. Sysinfo won't crash anymore and results are slightly faster than previously.
Replace your libs:68060.library with this one: http://www.winuae.net/files/b/ACA500_Blizzard1260_Hack.zip
(DO NOT USE if you don't use it with ACA500!)
It is Phase5 68060.library patched to not clear ITT0 and DTT0 registers. (Transparent translation registers that ACA500 uses to mark lower 16M as uncacheable for both data and instruction), these registers have priority over MMU tables.
Note that most likely any debugging program (like enforcer) won't anymore work with chip ram (or any ram inside first 16M), also this hack won't work if any program touches ITT0 or DTT0.

I really didn't except it to work but it did. Even whdload seems to work.
What do you mean? What says it?
It surely disables MMU and TTRs completely while doing system checks.
Too old program that knows nothing about 68060?

i expect its the cpu060 command throwing up the no 68060 found..
workbench 3.1 know nothing of the 68060 anyway , neither does sys info...
all working , even doom zips along at a fair old lick...and in OCS with 512k chip ram...amazing
another vid (shakey) uploading

thanks Steve it works great , stable and very quick ....
I'm amazed!
i wonder if Jens knows yet...
anyway... lets see what OCS stuff i can get running, SCUMMVM is ECS so that doesn't work. lots of demos complain about my cavernous 512k chip not being enough... pah
