There is no longer any format-specific code in the patch: http://people.brandeis.edu/~jcoiner/qemu_idedma/qemu_dma_patch.html You might want this patch if: * you run a multitasking guest OS, * you access a disk sometimes, and * you wouldn't mind if QEMU ran a little faster. Why I have not got feedback in droves I do not understand ;) -John
