Modified ROM Updates (Generic & iBook)
« on: March 11, 2015, 08:12:13 AM »
As some may have noticed, I haven't been around in a while. The development of additional ROM and extension modifications has been halted for the time being.

Of course that doesn't mean this project is finished. Should new developments or discoveries come to light, I don't see why we can't continue to experiment with these modifications to the Mac OS as time allows.

This is a rather time consuming project, and recent events have moved this one down the list of priorities somewhat. Between running ThinkClassic, my studies and finding time to spend with my significant other, dedicating several hours or even days to disassembling the Mac OS has become a rather tall order.

That said, another round of updates was made available two months ago in January. These were mostly overlooked however, buried deep within the forum thread over on ThinkClassic, so I'm making them known here officially with this thread.


I have omitted the download links for these packages from the post below. The reason for this is nothing personal - I'm hosting them from my own private account, and I can't guarantee that they will remain there (as a matter of fact, I'm almost certain they will eventually be moved elsewhere). Since I have greater control over that thread and can update it as necessary, I'll direct members from here to that post for up-to-date information on where to find these packages.

Time for another release. I wanted to release these now in their current form since I won't be able to commit to a time-frame for another release. Significant life events and recent difficulties have moved development of these down the list of priorities somewhat.


Macintosh ROM 10.2.1v1 "Generic"

* This release replaces the "Mac OS ROM 10.2.1 (Generic)" ROM.

These enhancements for the Macintosh operating system allow for the installation and use of Mac OS 9 on hardware released after Apple ceased support for Mac OS 9, henceforth referred to as unsupported machines.

Release 10.2.1v1 allows some unsupported Macintosh models to boot into Mac OS 9. This "Generic" release does not have any hardware-specific optimisations, and works best on machines like the Power Macintosh G4. While it can be used across a number of models of Macintosh desktops and notebooks, some features like notebook-specific power management or built-in display backlight control may not function correctly on some systems.


Changes

10.2.1v1 introduces a number of revisions from the standard Macintosh system, including:

   Mac OS ROM

   - Enables OS 9 as a valid boot option on MacRISC3 systems
   - Bypasses supported machine checks to attempt startup on unsupported models
   - Added model identifier names for Apple System Profiler:

         - PowerMac6,1 iMac
         - PowerMac6,3 iMac
         - PowerMac6,4 eMac
         - PowerBook6,3 iBook G4
         - PowerBook6,5 iBook G4
         - PowerBook6,7 iBook G4

   - Updated ROM version in About This Mac to Macintosh ROM 10.2.1v1
         - Previously Mac OS ROM 10.2.1
   - Updated Package Info to Macintosh System Component
         - Previously Mac OS CPU Software 5.9

   Insomnia

   - Prevents computer from automatically entering sleep mode (see Known Issues in included Read Me First)

            
This release is also recommended for users of the Mac OS ROM 10.2.1 (Generic) release as it contains a number of bug fixes:

   - Fixed incorrect string length for PowerBook6,3 iBook G4 in ntbl resource
   - Fixed incorrect number of ntbl entries

(See ThinkClassic thread for information)


Macintosh ROM 10.2.1r1 "iBook"

This release contains the complete set of files from my PowerBook6,3 iBook G4.

These enhancements for the Macintosh operating system allow for the installation and use of Mac OS 9 on hardware released after Apple ceased support for Mac OS 9, henceforth referred to as unsupported machines.

Release 10.2.1r1 is specifically intended for use on the iBook G4. It contains a customised version of the Mac OS ROM with improvements specific to the iBook G4, system extensions to provide limited support for the iBook's built-in video hardware and display, and a ColorSync profile to correct gamma for iBook displays that appear overly bright or "washed out".


Changes

10.2.1r1 introduces a number of revisions from the standard Macintosh system, including:

   Mac OS ROM

   - Enables OS 9 as a valid boot option on MacRISC3 systems
   - Bypasses supported machine checks to attempt startup on unsupported models
   - Patched backlight NDRV to enable brightness control with mnca backlights
   - Added model identifier names for Apple System Profiler:

         - PowerBook6,3 iBook G4
         - PowerBook6,5 iBook G4
         - PowerBook6,7 iBook G4

   - Updated ROM version in About This Mac to Macintosh ROM 10.2.1r1
         - Previously Mac OS ROM 10.2.1
   - Updated Package Info to Macintosh System Component
         - Previously Mac OS CPU Software 5.9

   ATI Via Driver

   - Custom NDRV extracted from OS X Panther enables basic framebuffer support
   - Resolution Switching Enabled (640x480, 800x600, 1024x768 on iBook)
   - Color Mode Switching Enabled (256 Grays, 256 Colors, Thousands and Millions on iBook)
   - Hardware Scaler (Lower Resolutions scale up to fit the entire LCD)
   - Backlight Control (when used in conjunction with 10.2.1r1 ROM on iBook)
   - Display Sleep and Backlight Dimming Enabled
   - VRAM amount detected correctly

   ATI Resource Manager

   - v3.1.6, Mac OS CPU Software 5.9 included (unmodified)

   Insomnia

   - Prevents computer from automatically entering sleep mode (see Known Issues in included Read Me First)


This release is also recommended for users of the Mac OS ROM 10.2.1 (Generic) release as it contains a number of bug fixes:

   - Fixed incorrect string length for PowerBook6,3 iBook G4 in ntbl resource
   - Fixed incorrect number of ntbl entries

Your contributions are greatly appreciated :)

Take all the time off you need; your previous work has helped (and will help) many others in the future. We can mirror any files you wish here. Your studies are very important (and so is keeping your girl happy), so we all understand... at least until the new improved Hologram Slut Systems come out in 2020, then we will not be as dependent on the ladies.

To understand what machines are OS9'able with this updates:

Previous MDD FW800

PowerBook6,3 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerBook6,3
ATI Mobility Radeon 9200

PowerBook6,5 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerBook6,5
ATI Mobility Radeon 9200

PowerBook6,7 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerBook6,7
ATI Mobility Radeon 9550


So, All iBooks G4?

eMacs PowerMac6,4 eMac are 2 models http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerMac6,4

Apple eMac G4/1.25 (USB 2.0) http://www.everymac.com/systems/apple/emac/specs/emac_1.25.html This model has ATI Radeon 9200 graphics with 32 MB of dedicated DDR SDRAM. There were OS9 drivers for 9200 not mobility. It could be the best supported unsupported machine (aside the first iMac G4 "X-only"). It has PowerPC 7447a and 512k on-chip level 2 cache runs at processor speed. Stronger than a cube, for example. Probably slower than a 1GHz Ti Powerbook (?). But this thing supports 3.5'' IDE with 7200rpm

Apple eMac G4/1.42 has ATI Radeon 9600 graphics with 64 MB.

Looking for MacOS 9.2.4

It has been a difficult time since my last round of updates here, especially the last few weeks in particular. She's been keeping me going through all of it though. (Cue Awwwwww.)

I'm not opposed to the idea of having these files mirrored here. They're self contained archives containing the necessary extensions and some documentation about what they do, how to use them and how to install them, so they should already contain everything most users would need.


To understand what machines are OS9'able with this updates:

From what I can tell:

Previous MDD FW800 - Confirmed Working.

PowerBook6,3 iBook G4   [ http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerBook6,3 ]
Mostly Working. ATI Mobility Radeon 9200 framebuffer is usable but lacks hardware 2D/3D acceleration. Sleep Mode is not supported, the system will sleep but be unable to wake, requiring a hard reboot. AirPort Extreme does not work. All other functions of the machine work correctly.

PowerBook6,5 iBook G4 (Early/Late 2004)   [ http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerBook6,5 ]
Mostly Working. PowerPC 7447A processor requires OF commands to identify to Mac OS 9 as an older G4 CPU. Multiprocessing folder must be removed from Extensions folder prior to first boot. ATI Mobility Radeon 9200 framebuffer is usable but lacks hardware 2D/3D acceleration. Sleep Mode is not supported, the system will sleep but be unable to wake, requiring a hard reboot. AirPort Extreme does not work. All other functions of the machine work correctly.

PowerBook6,7 iBook G4 (Mid 2005)   [  http://www.everymac.com/ultimate-mac-lookup/?search_keywords=PowerBook6,7 ]
Unlikely to work. Initial testing shows the machine hangs during startup. Possibly requires further investigation to determine if this machine is capable of booting into Mac OS 9. ATI Mobility Radeon 9200 extensions are unlikely to work with the Mobility Radeon 9550 without further modification.


I haven't tested the eMac models personally, but I'm hearing some success with earlier OS X-only models. The ATI Radeon 9200 extensions still need to be patched to determine whether they can be made to work with the onboard graphics in these models.

Some PowerBook G4 models, including the earlier 12", 15" and 17" models, also appear to work in a limited capacity. The main issue there seems to be the graphics hardware, and while I've looked into nVidia's extensions to see if they could be tweaked to work, they're a completely different beast to ATI's extensions and somewhat harder to understand and work with.

Fairly new here. Is there any harm in upgrading the graphics card on my FW 800 1.25 G4? I currently have the standard Radeon 9000 Pro but I know that Radeon makes better cards and so does NVIDEA. I have it booting 9.2.2 using the 10.2.1 ROM supplied here.  I don't know if that would throw off anything?  Thanks!

Bu, I'm not sure if that's a compliment because you think I can help you or an insult because I'm your last resort…

Buy the machine. Use the OS9 on file here specifically for it. The FW800 ports will operate as FW400 so all you need there is a couple of 3-dollar adapters. English, Swedish, whatever will work if you have the language pack installed. Boot it and enjoy your 1.42gHz OS9 computer.

i wonder if anyone sgot successful doin this unsupported journey on a non-english OS. my cloudy brain realized "language pack" is not the same thing as the language specific Mac OS ROM. i did try cheating (putting the updated ROM in the swedish system) but for one thing the sound panel settings locked as if occupied by an application. for some reason i find the swedish OS cute compared.
 
else i have to start learning some english...

whatever a "language pack" for OS9 is, but the ROM contains close to nothing in a specific language.

You are wrong. There are ALRT, DLOG, STR, STR# etc... resources in localized languages.
Please don't PM about things that are not private.
