Hi there, First of all, thanks for everyone who let me know that I had to assign IRQ11 to ISA in the BIOS to be able to use from an ISA slot. It worked. Now I have a working ISA frame grabber but the frame rate is rather low (~7.5 frames/sec). The DMA takes only 32 ms but it takes ~100 ms to put a frame to the screen in an X window. This seems awfully long. How could I decrease that 100 ms to 15-20 ms?
