<p>Ischmave: /* Dev Nodes *subject to change* */ new section</p> <hr /> <div>Um, on any Mac OS block device diskXsY has a character device counterpart called rdiskXsY, so rdisk0* is just a character device for accessing the flash.<br /> <br /> <br /> ! Ahh! Thanks for that correction [[User:MiW|MiW]]<br /> <br /> == lol ==<br /> <br /> on the same topic as above...rdisko is not ramdisk...do you know what ramdisk means? :)<br /> <br /> <br /> <br /> I do know what a ramdisk means yes! Why is it so strange that there would exist a ramdisk device node? The device must read the ramdisk contents <br /> from flash before it copies to ram right?<br /> <br /> Ive had my device for a little under 4 days now, and from a linux background so I am not totally sure how<br /> OSX/BSD handles it all. Im just trying report all the info I find.<br /> [[User:MiW|MiW]]<br /> <br /> <br /> Also, maybe add /dev/kmem and /dev/mem as blocked nodes<br /> <br /> <br /> &quot;blocked nodes&quot;? Does the kernel prevent the user from reading from these nodes?<br /> Oh and i am totally right about the GPS.<br /> <br /> MiWs-IPhone:/usr/libexec root# strings locationd82 | grep dev<br /> /dev/dlci.spi-baseband.9<br /> <br /> [[User:MiW|MiW]]<br /> <br /> == my bad ==<br /> <br /> Sorry about that dude, didn't notice the GPS thing. I'll be sure to use the edit button next time :)<br /> <br /> Now that I think of it, you made a simple mistake that anyone could have made. To clarify:&lt;br<br /> /dev/rdisk0 - Raw Disk&lt;br&gt;<br /> /dev/rd0 - Ramdisk<br /> <br /> Yes, you are correct about the blocking. The only way to get access again is a LOT of kernel patches as well as some userland patches, such as to launchd. The only person who has been able to accomplish this is scotty2, a great hacker, but he seems to have disappeared :( The only other time we had access was in 1.0.2 when they were not blocked nodes<br /> <br /> == Dev Nodes *subject to change* ==<br /> <br /> Hello,<br /> <br /> i think we should cover something about the way Xcode mangles your iPhone when in &quot;developer&quot; mode (which really just means it restricts it even further<br /> <br /> for insance a whole new dev node /dev/disk1 is created which houses the gay developer files/sandbox<br /> <br /> xcode loads a ram disk image every time a dev phone is connected...</div>
