I plan on taking a look at the compiler warnings here shortly. But I have not tested out how much works on the C200+ with a 64-bit kernel ... I have no idea if scsi works, etc. I will play with it more and see what is br0k3n.... I was just happy to see the login prompt. > btw, does a 64-bit kernel with the 32-bit wrapper options enabled boot > on a PAT PDC box like A500? I'm not sure if I understand the question, so let me try to restate the question I think you are asking. If you compile in 32-bit wrapper support into a 64-bit kernel ... can the same kernel be used on a PAT PDC box like the A500? No. When I first started down the 32-bit wrapper support, I was going to make the wrappers smart and use the 32-bit wrappers when needed. I was talked out of the idea, because on all the boxes that need the 32-bit wrappers do not support > 4G ram, thus there is no advantage (yes Grant, I know ... some application do benefit from 64-bit kernels) for running a 64-bit kernel on them. The PDC wrappers are designed to be used for developement/testing purposes for people with these systems. (By Making the wrappers a compile time option, it saves an additional level of indirection for every pdc call). That help? If not, I'll try again. - Ryan
