My ide controller is a CMD Technology 646U2 DMA controller, but menuconfig will only allow me to select 'CMD640' and 'CMD640 Enhanced'. I have read that the CMD646 driver will support "DMA mode" while the CMD640 driver will only support "PIO" mode. So, I would prefer to use the CMD646 driver even though that does not appear in the block-driver list from within menuconfig. However, both the cdm640.c and the cmd646.c source files came with the the current version of my kernel-source (2.2.12).
Should the CMD646 driver be appearing in my menuconfig block drivers? Is there a way to get the CMD646 driver to appear in menuconfig? If not, is it possible to manually compile the cmd646.c source and apply the resulting driver to my system? Is there an easier way to achieve the use of this driver, even at the expense of a total reinstall? Thanks in advance for any help. - gladimir
