Well the AE cards should be DMA - you are not DMA compatable over 4 meg anyhow, so your card (since you got a rom 03) should probably only be 3 meg. Unless you use 1 meg as a RAM disk - but I don't know if that would work or not - I'm guessing it would as the RAM disk is generated in high memory leaving the lower 4 for DMA. I have no ideas about the Chinook card, but the CV Tech card seems to be a good deal from what I've heard (back cover on your current GS+). Basically get the cheapest since they all work. Just stay away from older brands. All new ones should be just fine. -- ===> Josef W.

Unless you use 1 meg as a RAM disk - but I don't know if that It's my understanding that all motherboard RAM is DMA compatible, and stuff in the memory expansion slot is DMA compat up to 4 megs, so on a ROM 1, you can have a total of 4.25 Megs DMA, and on a Rom 3, you can have 5.125 Megs DMA. >would work or not - I'm guessing it would as the RAM disk is generated >in high memory leaving the lower 4 for DMA.
