Again: Tmp. disable BlkVSC (paravirtual IDE) functional? On ATA Channel N2 -- minimum Re: Disabling ATA driver for IDE devices on Hyper-V Re: ATA controller and Hyper-V synthetic storage driver hand
Hi! This may have been asked before but the solution we have currently is less than ideal. Please bear with me on the repetition and provide any suggestions you may have. One of the issues with Hyper-V is that it does not virtualize the CD device and therefore we rely on the ATA driver in the guest operating system to manage CDROMs. What we would like to do is disable the ATA driver for all device types except the CDROM in the presence of Hyper-V.

That is why you can't replace driver for a single disk in the same way as you replaced driver for the whole controller. The highest level present in NewBus is ATA channel.

Good day! I don't know is it possible to build kernel with CLANG, because now my system builded without clang, so right now I can rebuild world only with gcc (because clang is not present in my system), or maybe I can install clang from ports and rebuild world with clang from ports? 30.09.2013, 02:29, Abhishek Gupta (LIS) abgu...@microsoft.com: Hi, Is it possible for you to compile with the clang compiler instead of gcc?
