Attached is a screenshot of the crash I obtain when booting with "Second limit-breaking ROM".

Damn ! We were going so quick thought we would have the full extra 512MB by midnight

All joking aside, this is absolutely amazing, even stealing 64MB is like XMas considering Apple never intended to throw us even that small bone.

That's a pretty miserable crash, but very fixable. My PageMap patching code is very hacky, and made some clearly incorrect assumptions about the state of the map on other people's machines. I should have a fix in a day or two.

So thanks for testing, guys. I'll have another image for you in a couple of days. If you're willing to believe that the second image does work, then we're up to 1.625 GB.

If this is of any use or you need the log for the original ROM, let me know. Oh, and the archives seem to be working correctly now with Classilla and Stuffit Expander in OS 9.

ELN · « **Reply #105 on:** June 04, 2017, 02:00:42 AM »

Hi everyone,

I have added a new component to the Mac OS ROM: the "Wedge". The Wedge is a chunk of C code inserted into the ROM that runs between the Trampoline and the NanoKernel. It takes the structures prepared by the Trampoline, carefully patches them, spits out some textual debug output, and then hands control to the NanoKernel. The debug output remains hidden in memory while the machine boots up. Once (and if) the machine is booted, it can be read by a small app, WedgeLogReader.

At present the only task of the Wedge is to expand the main segment of Mac OS memory. This allows an extra 128MB of RAM to be used, on top of the 1.5GB limit.

Why go to the trouble of bootstrapping a C runtime? Two reasons:

Ease. Patching the PageMap is too complex to accomplish reliably in RISC assembly (see the crash reports above).
Portability. The code can be tested on your machine in userspace before risking a crash on boot.

And what cool stuff is in the attached archive?

PowerMacInfo, in case you didn't already have a copy. This will crash on a Wedge ROM, because it hardcodes the InfoRecord Page address.
WedgeDryRun, a text app to test the Wedge code on your machine. If this crashes, let me know.
Mac OS ROM, with all the trimmings. Besides bumping the RAM limit slightly, this should work on all unsupported G4 desktops (including the 9serve, MacOS Plus!). The annoying NanoKernel log window is off by default. If you find it stable and you want the extra RAM, then this is ready for production use!
WedgeLogReader, a text app to dump the Wedge log left over from boot. Naturally, it only shows useful information if you booted with the Wedge.
NKLogReader, again in case you didn't have a copy.

Those testers who had trouble with the previous patched ROMs, would you please try this out? The best information to post would be: WedgeDryRun output, WedgeLogReader output, NKLogReader output, and before/after screenshots of About This Computer. Please post text inline! That way I can read it on my phone, and it gets indexed by Google.

For the morbidly curious, here is the Wedge C code. The same code runs in both the attached ROM and the WedgeLogReader. I don't suppose that one of the admins feels like changing the tab size to 4?

Handing over to the NanoKernel.

Out of curiosity, technically speaking, what stops you to extend the usable RAM space beyond the 128mb you already extended onto?

Very good question.

Note the "nontrivial PME" lines in the output above. These list the areas that the Trampoline instructs the NanoKernel to locate in logical memory, in addition to the MacOS logical area starting at address zero. The Wedge is moving two of them to a location much higher in memory.

The first one is the InfoRecord Page (IRP). With that at 5fffe000, the main area can only expand to a whisker under 1.5GB. By moving the IRP and another small area at 64000000, we can expand up to the next obstacle at 68000000 (which is actually a mapping of the upper megabyte of the ROM, and is not listed in the PageMap above). This gives us 1.625GB. With luck, we will get the full 2GB soon.

The data and code in these hardcoded areas mostly concern the interface between the low-level PowerPC system and the high-level 68k system. There is rarely a need for application code to access them directly, and there are (usually) ways of querying their addresses at runtime, but some software still hardcodes them. Moving them therefore presents a small problem for application compatibility. For example, moving the IRP seems to crash PowerMacInfo and Apple System Profiler (and the 68k DR Emulator, but that's fixed). A similar problem arose when the first PCI Power Macs moved the ROM image from 40000000 (1GB) to FFC00000 (just below the 4GB mark). I suspect that this is the cause of the instability reported on Macs with more than 1GB of RAM.

Great explanation! Hoping for the best so I can make use of all the memory in my MDD. Not that I ever used the full 1.5GB usable right now, but anyway

Daniel · « **Reply #109 on:** June 04, 2017, 06:14:30 AM »

I just tested it out. It works! I don't have any 2 GB macs, but it works just fine on at least one system. Here are the Wedge and NK logs if they are useful.

It Works!

AWESOME !

Handing over to the NanoKernel.

Before/After RAM stats same as the results with the MDD (as expected), so I won't bother with additional screenshots. BTW, posting this from the 9serve!

I just added 256 MB or RAM to my main working computer (a G4 MDD) and I started to do real life test, In this picture we can see Cubase using 1.54 Gb or RAM, (mainly loaded by Kompakt sampler instruments). No problems by now ...

I figured you would be the first to max it out with synths! When we eventually get the full two gigs, please give us a report on latency.

We should inform the other forums about this ! This is pretty crazy... 15 years after the OS 9 funeral it is getting a genetic overhaul,
128MB might not seem like much until you consider that 128MB is what many users had in the Classic Mac OS era to run OS 9 and all their applications.

In the big scheme of things, this is quite remarkable

Remember a time when a 128MB DIMM stick wasn't just a leftover at the bottom of your spare pile? Nostalgic...

This is good to see! We are considering some other ways of pushing the limit even further. It might require us to patch the Process Manager to divide up its heap. It would be very useful for me to know the memory layout on your machine running Cubase.

Would you mind collecting some data for me? A screenshot of this app while Cubase is running, and the details in the Memory panel of the Get Info window for Cubase.

And by the way, is it possible to enable VM on a machine with 2GB of RAM? Would someone mind checking?

If I recall, there is a point where you can no longer turn on virtual memory because you have enough RAM. I don't recall off the top of my head though.
