Excellent work - running the entire install phase on real hw is a great step forward! (Much bigger achievement than running in emulator) I will study your findings!

On a related note, I updated the boot floppy build (powermac-nt-hal) to not include any Microsoft code at all, i.e. everything on that floppy is now built from source:


Next, I'm trying a few things:

A) Try to get NT to boot from "normal" (non-NT) ANS rom

B) Try to boot NT on emulated TNT (9500/8500)

C) Try to boot NT on real TNT (e.g. 8500) hardware.

Thank you! I might just need a small break, you might take a look and see something quickly and then I can pickup again.

TBH again like you said, getting it to a point on real hardware going through the NT setup is pretty cool! Thanks for the note about the floppy part removing Microsoft code, Ill have a look at that.

Also AMAZING work on the OS/2 PPC!!!

Quick update, I'm going to have to pause work right now because I have hit a pretty big roadblock after a successful Windows NT 4.0 on my 700.

The roadblock starts after the first reboot directly after Windows NT is installed on the internal drive. Just the fact that the install process is working is very encouraging.

@ClassicHasClass I posted my update here https://github.com/MrMacintoshBlog/powermac-nt-hal/blob/main/docs/ANS-HANDOFF-2026-11-05.md

@PappaDF Thank you also so much for your help, if you see anything that my AI tool is missing please let me know. We are getting close but also seem far away.

Windows NT bringup will be longer side discussion, and in order to not pollute this thread more than already done, I started a separate side thread about Windows NT specifically: https://tinkerdifferent.com/threads/windows-nt-4-0-on-the-apple-network-server-and-tnt-macs.5724/

Hope that everyone is ok with that.

Thanks for that. I've attached the result of parsing that dump with my parseOFlspci command (included in the "lspci for Open Firmware.zip") which uses lspci.

I welcome dumps from any Power Mac or ANS that has different results.

Does AIX have pciutils with lspci? I suppose someone could port pciutils to Mac OS 9 either as MPW tools or as SIOUX apps.

Using ANS ROM 2.0 to boot Mac OS is discussed at
https://68kmla.org/bb/index.php?threads/mac-os-on-ans-modding-a-rom-dimm.51120
A ROM SIMM from a Power Mac 7100 is used.

According to testing done at #48 , a PCI device at device number 0x11 (usually an 53C825) connected to the first PCI bus (@F2000000) will cause the ANS startup code to perform a Testing Parity DIMMs when the revision is not 2 (pci config space register at offset 0x08).
Since @ClassicHasClass 's ANS has a 53C825 with revision 0x11, he should get the Testing Parity DIMMs message.
(using ROM 1.1.22 - I haven't checked all the other ROMs)

Does anyone have an ANS that doesn't do the Testing Parity DIMMs test?
