It seems to work well -- I haven't done any benchmarking, but subjectively it seems to make a difference. However, I tried enabling DMA in the Windows 98 system settings for the C: drive, and that doesn't work -- when I reboot the emulator, it stalls fairly early in the boot process. Have others been able to get DMA working (with the patch) with Windows 98? Is there something I could to try to track down the problem (assuming it is supposed to work).
