32-bit mode works ok in snow leopard, but 64-bit mode can not load 32-bit kexts so devices are not detected. a new kext would need to be created to be 64-bit compatible...
note: 64-bit mode seems to load only with the 6-4 key combination at boot...
Hi, just curious if there are plans to do a 64-bit kext and if so when? Thanks.
I attempted to compile the source against the 10.6 SDK in xcode to no success. It looks like not only the source for the kext uses UInt32 extensively, the IOSerialDriverSync class in the SDK does as well.
One of the things that is needed is either my patch (2897585) or Ryan's (2202541). GCC 4.2 is needed to compile 64-bit kexts, and gcc 4.2 seems to have found a bug in the code.
As for 64-bit Kernel mode: some Mac Pros and Xserves boot in 64-bit mode by default.
