What I have it set for is burst on and maprom **. Any other setting that work well for a1200 with 3.1rom aca1233?
Use this line for ACA1232/1233 cards:
C:ACATune -cache on -burst on -vbrmove -maprom * >ram:acaoutput.txt
If you want to you can open the subsequent acaoutput.txt file with multiview to check that everything has gone okay with your acatune command. I believe after the first reboot it will change to "Kickstart already re-mapped" or something like that, which of course is perfectly normal.

It's my preference to create that little text file in ram: , but if you don't want any feedback on how the acatune command runs then use this line instead:
C:ACATune -cache on -burst on -vbrmove -maprom * >NIL:
