It's all just software of course, but it seems like a lot of work for little reward. Why are you thinking about this? What, in particular, would get "merged"? Do you mean something like shuffling two decks of cards together, or making a marble cake? Justin, while this is only at best marginally related to what I think the OP was saying, I can think of a number of reasons to want to glue Slowlaris and Darwin together: * launchd or asl on Solaris * Solaris TCP/IP for Darwin * massage the solaris LWP API into mach threads on Darwin, or the opposite (perhaps a libslowlaris.dylib to make app porting easier, I don't know, seems like a lot of graft to me [pun intentional]) * Solaris userland for Darwin (although I can only imagine doing that if I were bringing it over to PPC, not Intel because there's already Solaris userland for Solaris on Intel). Of those, none strike me as fantastically interesting. Destroying SysV init and replacing it with launchd is a mildly amusing notion, but I thought (hoped) I'd left the Solaris world behind.

But what are you going to do with this information? Most people who ask this question immediately turn around and ask "How do I do I/O to these blocks?" That's a much harder problem, and I think it would be better if we resolved the hard problems before tackling the easy ones. What I need from you is an overall description of what your product is trying to do. From reading your questions to this list, it seems that you might have taken an early wrong turn (trying to use an I/O Media filter driver as a replacement for a file system filter driver), and are now very much lost. I'd like to take a step back and ensure that you're on the right track before we push deeper into the jungle. I recognise that you might have concerns about discussing your product on a public mailing list. If you'd prefer to handle this in private, you can open a DTS tech support incident and I can help you one-to-one. This email sent to site_archiver(a)lists.apple.com

If you just need one of the Open Firmware variables, then you can look at the properties of the /options node in the device tree (with the standard IORegistryEntry getProperty methods). If you need something else, then the /options node is an IODTNVRAM, so you can look at IONVRAM.h to see how to talk to it. Depending on what you want, you might be interested in readXPRAM or readNVRAMPartition. Actually, it's probably easier to call the related methods in the platform expert (they are basically wrappers around the IODTNVRAM methods) -- see IOPlatformExpert.h. One trick when doing this from a driver is that the nvram driver may not have loaded yet when you are in your start method (the nvram driver is just another driver, so it may load before or after yours). There would be different ways to deal with this, depending on what you're trying to do. _______________________________________________ Do not post admin requests to the list. They will be ignored.
