It was a lot messages with questions about how to use XT-bridge board memory on Amiga side. The answer is very simple: You need to use "addmem" program to add XT-memory. "addmem" takes two parameters: start-address, and end-address, as usual it is: 200000 and 2a0000 addresses, but you can check your XT memory physical adoeresses by using any debugging tools with allows to examine memory. example: addmem 200000 2a0000 If you haven't this program I can send hex dump of this program (it is very small)... About VGA mode: There are DFF1C0 - DFF1FF new FatAgnus registers. I don't have any information about these registers. If some one know pls give me know. But I know exactly that if you put 0 value to register DFF1DC you will turn your Amiga in NTSC mode, if you put 20 value you will get PAL mode... example: move.w.#00,$DFF1DC - NTSC move.l.#$20,DFF1DC - PAL if you have VGA monitor you can try 10,20,30,40 and so on values, one of these turns vga mode. I didn't test it because I haven't VGA monitor. ======================================================================== | Sergei V.
