So far, only ANS ROM 2.0 can boot Mac OS, therefore only an ANS with that ROM can use the TNT flasher but I don't think anyone has tried it. The ANS is very much like a TNT Mac so it should be possible. You can find schematics for the TNT Macs (e.g. Power Mac 9600) that show the pinout of the...

The TNT flasher only handles two types of flash chips: AMD Am28F020 (01h:2Ah) or Intel 28F020 (89h:BDh). And the flasher has a bug that makes it not work correctly with the Intel 28F020 chips. The flasher utility doesn't detect the flash until you ask it to do the flash. At that point, if the...

Did you try hard-coding a size greater than 64K to see if anything else gets dumped? The current SlotsGrab updated today only uses the smallest power of 2 that fits the DeclROM.

The hard drive should have the Mac OS 9 drivers when it's first formatted so that there's sufficient room to keep them all. I suppose one could try moving partitions to make room for the drivers (just needs 1824 blocks for all of them). Try iPartition.app 3.3.1 in Mac OS X 10.4? Use my...

I said a compressed ROM with the ndrv won't fit but an uncompressed ROM without the ndrv will fit. I posted a ROM for the latter case and the ndrv needs to exist in the OS somewhere. If you can't find the ndrv on the OS, then we can add it.

That makes sense. R133 is connected to PLL_CONFIG1 which is PLL_CFG1 of the 603ev CPU. You can access these bits in the HID1 register of the CPU. hid1@ 8 u.r The most significant bit is PLL_CFG0. DingusPPC hardcodes HID1 to 0x70000000 (225MHz). @powermax mentioned the Gazelle schematics which...

Look at the code that produces /tmp/filelist3.txt The file list includes md5 for comparing data forks, and size of resource fork. 0 = no resource fork. 286 = empty resource fork. I convert all the files to MacBinary to preserve file type/creater, dates, flags. I suppose the files missing...

Does overclocking or under clocking affect any of the bits of f3000034 ?

To make sure the macbinary command always produces the same result file, I use SetFile -a avBStclInmedz to make sure all the files have the same finder flags (bundle, system, inited). Attached the stuff I used to compare ROMs from the three forks.

Which Mac model is that from?

Anyone with a 5500/6500/TAM able to get the value returned by this command in Open Firmware? f3000034 rl@ 8 u.r

If the system doesn't have an ndrv for this device ATY,Piranha then I guess you'll need to add it to /System/Library/Extensions/AppleNDRV perhaps as a new bundle or appended to an existing bundle.

The ROM requires only 24K with the ndrv removed. I remember trying to create a compressed fcode image for this card that includes the ndrv but the original fcode is too large and the compression ratio is between 54% and 65% (using lzss). Maybe there's a better compression algorithm, but the...

You should rebase your fork to the current upstream master before doing a pull request. You should use interactive rebase, then fixup to combine multiple related commits into a single commit to clean things up. You should remove the original .rom files after converting them to .zip. You should...

CODE resources are handled by the Segment Manager. Mac OS X PPC or Rosetta can use PEF apps in user space (Carbon apps). In kernel space, I think only IOGraphicsFamily uses PEFs.

PEF is not a thing in Mac OS X except for the ndrv for a GPU used in a IONDRVFramebuffer (subclass of IOFramebuffer) kernel extension. An IONDRVFramebuffer allows most any GPU that works with OS 9 to be usable in Mac OS X without having to create a new driver. New drivers are required for 2D/3D...

In Mac OS 9, the Code Fragment Manager handles PEFs which are shared libraries. In Mac OS X, there's a PEF loader in IOGraphicsFamily which loads an ndrv into the kernel.

I don't understand this. Power is Voltage x Current. Current is Voltage ÷ Resistance. A power supply controls voltage. The load controls/is resistance. Maybe "Adaptor supplying too much power" means too much voltage? The load controls current. If the load tries to take too much current (a low...
