Mac OS 8.6 edit Released May 10, 1999, Mac OS 8.6 added support to the Mac OS nanokernel to handle preemptive tasks via the Multiprocessing Services 2.x and later developer API.
#Mac os 8.6 rom update#
PowerMacInfo, distributed in the Multiprocessing SDK, is an application that displays statistics about the nanokernel's operation. Mac OS 8.5.1, released December 7, 1998, was a minor update to Mac OS 8.5 that fixes several bugs that caused crashes and data corruption. Vega to add Multiprocessing Services 2.0 support. Mac OS 8.6's nanokernel was rewritten by René A. This evolution would later affect the overhaul to the nanokernel in Mac OS 8.6.

The DayStar Digital Genesis MP Macintosh clone requires kernel extensions to support multiprocessing. The Open Transport networking architecture introduced standardized PowerPC synchronization primitives.

A forward-looking architecture was introduced for PCI card drivers in anticipation of the Copland microkernel called NuKernel, which supports memory protection. Progress after 1994 demanded additional functionality. This nanokernel is stored on the Mac OS ROM chip integrated into Old World ROM computers, or inside the Mac OS ROM file on disk on the New World ROM computers, rather than being installed in the familiar sense.

However, as the software is little documented, these might instead be handled by the emulator running in user mode. Other tasks may include switching back to PowerPC mode, if necessary, upon completion of the interrupt handler, and mapping the Macintosh virtual memory system to the PowerPC hardware.

The operating system does little until activated by an interrupt, which is quickly mapped to its 68K equivalent within the virtual machine. Bad character height: In Mac OS 8.6, the height of characters in Apples Japanese and Traditional Chinese fonts is one pixel. As such, the normal state of the system is to be running 68K code. Its main purpose is to allow the existing Motorola 68K version of the operating system to run on new hardware. The original nanokernel, and the tightly integrated Mac 68k emulator, were written by emulation consultant Gary Davidian. The nanokernel is very different from the Copland OS microkernel, although they were created in succession with similar goals. Unlike the 68K-derived Mac OS kernel running within it, the PowerPC kernel exists in a protected memory space and executes device drivers in user mode. The second major revision supports multitasking, multiprocessing, and message passing, and would be more properly called a microkernel. The initial revision of this software is a single tasking system which delegates most tasks to an emulator running the Motorola 68000 series (68K) version of the operating system. Mac OS 8.6 needed other comments Regarding the Mac OS ROM 1.0 Update (mentioned here last time), Apple TIL article 60408 notes that the updater requires Mac OS 8.6. The Mac OS nanokernel is an operating system kernel serving as the basis of most PowerPC based system software versions 7 through 9 of the classic Mac OS, predating Mac OS X. Nevermind that there is also an iMac Firmware Update 1.2. | | | TheReaderWeb | Wikipedia Mac OS nanokernel There is no separate update for that version. Of course, you'll need Mac OS 8.6 to get Mac OS ROM 1.4. What's the instant clue that Mac OS ROM 1.0 Update is newer that the iMac Update 1.1? Making life more interesting, iMac Update 1.1 updates the Mac OS ROM to, not v. They have to contend with iMac Updates 1.0 and 1.1, both of which also update the Mac OS ROM file. How is it that an update that updates a ROM from version 1.4 to 1.6 is labeled as 1.0? iMac users may be especially confused. What's in a name? Several readers (and you can add me to the list) query about Apple's recent strategy for version numbering and naming. Since applying this update, I've been using my machine in avariety of programs for at least eight hours with not a single freeze or need to re-boot." On the other hand, James Reid speculates that the Update may fix more than Apple is saying: "I've been experiencing frequent freezes in almost every program on my G3/BW Mac. Based on the info in Apple System Profiler, he suspects that the Update may not have actually updated his ROM.
