Welcome! The dual 867 MDD is a nice machine - have fun with it and let us know what you intend to do with it! (Mac OS computers want to be used; not dust on shelves ;-) )

Did you say why you wanted to use a version other than f63 with OS 9?

In the hope that it will correctly enable graphic acceleration on "silent upgrade" G4 Minis (1,33 and 1,5 GHz models) and permit using larger displays with them.
Since ELN and darthNvader haven't been seen here for about a year, someone has to pick up the torch

If you haven't followed this topic, which is scattered across several threads, here are a couple of links to get you up to date:

What does "v9 ROM file for Mini" mean?

Is there an ndrv in Open Firmware? If so, what if you remove it before booting OS 9? Or replace it with a newer version before booting OS 9?

This post by ELN explains everything:

What disassembler did you use? IDA? Which version?

The assembly listings show the imported libraries and functions as expected:
VideoServicesLib, NameRegistryLib, PCILib, DriverServicesLib

No unsupported libraries appear to be included. version f100 adds AbsoluteDeltaToDuration but that's not a problem since CIncludes shows that API as going back to Mac OS 8.6.

I don't see a device description, just "TheDriverDescription" as expected. The only difference in TheDriverDescription is the version number changed from 63 to 100.

Comparing the assembly listings would require renaming all the unnamed labels since they have different offsets or positions between version f63 and f100. In MPW you could create scripted menu items with command key short cuts to do the renaming of each label for you. It would work like this: select the label on the left and the label on the right. Choose a new common name for the labels. Have it verify that the new name is unused in both files, then have it rename all occurrences in the old version and the new version and re-compare. I did that with Open Firmware drivers. Open Firmware is different since the labels are order based (1,2,3,4...), rather than offset based, so that when renaming a label in Open Firmware, you could have it automatically rename all labels after that by incrementing there order number that is included in the label name thus greatly reducing the number of renames required.

Is there a modern utility to do a similar compare/rename? Does IDA have a compare binaries option? Can you change the assembly format to use order based names instead of offset based names? I suppose one could easily create a script to rename offset based labels as order based labels.

Welcome! I agree, the MDD is definitely the Mac OS sweetspot... Definitely my favorite machine in general. Then again, all of those machines are just really great... there is no going wrong with them.

Hopefully you enjoy your stay here!

Hello from the Boston area (35 miles north) I have been to the site a few times while rebuilding my dual 867 MDD. Finally registered to finally contribute to the site. I have not only been rebuilding the MDD, I also dusted off my 400 MHz Blue and White G3 and my PowerBook G4 (which I am trying this from). Been using Macs since 1994 starting with a PowerBook 180. Owned many but the sweet spot is the MDD.
