This Shouldn't Be Possible... 

Mjd & Action Retro the same video😂

Heh, well this was quite the coincidence! Cool to see that you got it dual booting

Windows on Mac - it's a Wacintosh

For dualboot, the HFS partitions created aren't formatted at all, you have to boot from an OSX CD (10.1 and above) and use Disk Utility to format the partitions. There's also a "reboot into OS9" option in firmware setup because OS9 refuses to use a hard drive with an MBR on it. (some OSX installers are the same, specifically 10.2 and 10.3 won't even format the HFS partitions if the drive also has an MBR on it) Regarding booting into NT, you should be able to boot from the OF shell by "boot ide0/@1:,\\:tbxi" or something like that, without needing the CD.

It kinda works because these computers were built in a brief period where Macs were semi-compatible with the CHRP specification which NT for PPC was meant to support. It wasn't possible to run NT on Macs before now mostly because there were no drivers for the ASICs Apple used (specifically the super I/O chip), but it looks like someone put in the effort to get it to (mostly) work. Apple's ASICs are always black boxes so writing drivers for them isn't easy. Odd that USB doesn't work though. On the B&W G3 it's provided by an OPTi FireLink chip (not the same as the FW chip which is from TI), which was extremely common on PCs in the era. Maybe it'll show up under Device Manager and you can install the drivers from there.

"alright, i've got my big bin of random IDE hard drives. I'm sure everyone has one of these"..... me furtively looking under the desk in the corner of my room: yup, true.

I remember being like 15 years old, and trying to boot any NT bootloader I could find in OpenFirmware on my Powermac 7600. I had gotten a PPC NT4 disk from my fathers work, and desperately wanted to run it. Obviously that wasn't work, but the information was so scarce that I thought it might. This is amazing.

sponsor on this one is wild. they don’t actually disclose how exactly their business model works. seems like you’re either paying to have your internet connection used for illegal activity without your consent, or paying to use the internet connection of someone who doesn’t know their network connection is being used for illegal activity

I’ve been PRePping for this moment for 30 years!!!

12:05 Windows and Mac used different partition record formats (aka "disklabels") on PowerPC. Windows NT on PowerPC carries forward MBR (Master Boot Record) from x86/IBM while Mac wants APM (Apple Partition Map). You generally can't format a single disk to have multiple disklabels, even if you can fit the partition tables into one another they'll still wind up getting overwritten by partitioning and formatting tools on other OSes. Apple fixed this with the x86 transition by switching OSX over to GPT (GUID Partition Table, not Generative Pre-trained Transformer). This was the new partition format for UEFI, and it ALMOST solved this weird dual-boot incompatibility, except Windows didn't ship GPT support until Vista (AFAIK). Since Boot Camp needed to dual-boot XP, they made it and Disk Utility actually write both MBR and GPT disklabels and keep them in sync. This "Hybrid MBR" setup (as Linux users call it) is really fragile, you basically have to partition the disk from OSX (or maybe gparted?) all the time while anything else will corrupt table or the other. And it's only possible because GPT is already designed to sit inside a "protective MBR" that just has one partition covering the whole disk. AFAIK you can put HFS partitions on an MBR disk, so... maybe try imaging the OS9 partition onto the NT drive? I'm not sure if you need to do something else to get OpenFirmware to boot it, though.

This is like cooking an omelet with mashed potato instead of egg: extremely weird and borderline criminal, but the result could be interesting.

Just need DOOM next, maybe NCommander can give some tips here 😂

Back in the day I had NT4 running on alpha mips and intel boxes but I never got the opportunity to run nt4 on ppc. So this is truly beautiful. Thank you so much for sharing

but does it run Crowdstrike...?

It always keeps coming back to Wack0 :o

Man that NT install disc was filthy. Lmao I can't believe that disc drive read it.😂

MacOS on Mac hardware, Macintosh. MacOS on x86 hardware, Hackintosh. Windows OS on Mac hardware, Backintosh.

Ahhhhh, double nostalgia for me! I had a B&W a while running OS X Tiger, and back in 2000 is when I got my MSCE and MCT (I was teaching the Microsoft tech classes), so I ran NT 4 A LOT! Thanks for this, it's great to see!

I never thought I'd see these two worlds collide.

MJD Dejavu?

I feel so bad, MJD beat you by one hour

WinNT for ARM... Does it run on raspberry pi? Yes, I know that there are modern windows versions for RPI, but is there WinNT?

Many... Many years ago i did the same installation test on a IBM RS/6000 , it was fun except there wasn't software available for Windows NT for PowerPC 😅. Thanks a lot for your video

Dammit Sean! I was trying to be the first one! 🤣 I have like two hours of disaster videos filmed and I still haven’t gotten it to freaking work I’ve been working on it since Monday night 😂

This was really cool project, consider original hardware that can run PowerPC version of Windows NT is an unobtainium these day and the emulator is nonexistence. Now we can also technically use PowerMac emulator to run PowerPC version of Windows NT too.

2:25 yup, I also have one of these... Few months ago checked and wiped all of them (and recovered some things that thought long gone)

Wow, this is crazy! Also, that blue-and-white Power Mac G3 is a work of art. I wanted one of those, back in the day. I had a Power Mac 8500 at the time, which I upgraded the heck out of it for years, but the Power Mac G3 was so pretty and easy to open and work inside it, compared to my 8500.

The first 4 mins of this video is a Edging Nightmare... lol You held C and then went to the Ad and I yelled "STOP BLUE BALLING ME" lol

1:55 wow that's a well designed case

These are the shenanigans i expect from this channel❤

That is dead-on unique & relaxin' i forgot Windows & Apple developed a computer possibly like that :D

This is the stuff I love about (retro/vintage) computing!

You'll probably want to install the latest service pack as well, it fixes a lot of issues. The last one should be SP6 or SP6a. Also, NT4 is free to get from Winworld anyway and basically abandonware at this stage :) (anything pre-XP is considered that).

What in the 90's wizardry! I always dreamed about this!

A "reverse hackintosh"? There never be a nerdier thing to have

Amazing! Now I wish I had kept one of the Power Mac G3s that I have given away over the past year or two.

Man these videos making me question the 90's

Oh wow. I just watched MJD’s video. His struggles were fun to watch. Let’s see how you do with it. :) I remember reading about the Alpha and PowerPC official ports. I think there was another architecture supported (other than x86). I think it was MIPS.

Finally Windows 3D Pinball on the mac... oh wait, it's just a demo of full tilt pinball...

About 25 years ago, I installed the DEC Alpha Windows NT once because that was the only PC available (chucked in an office corner). Unfortunately it wasn't very useful. The IT guy also had the DEC Alpha version of MS Office, but that's it. Are you telling me it had a built-in x86 emulator and I could have tried running whatever I wanted!?!?

Loved NT in the 90s. Super cool PowerPC (my favorite color combo) and neat to see you got NT running on it!

Genuine and authentic content makes these videos so relatable.

Cool hack :-) For the DEC Alpha there was FX32! which provided 32-bit x86 compatibility via a JIT compiler. Maybe something similar existed for PPC?

As soon as I saw this project I was hoping you were going to do it. I've wanted to make this abomination since I found out NT had PPC support.

So many crazy things being developed, and no one ever designed a mainboard that fits a PowerMac G3/G4/G5 "natively" without mods to the chassis... Even if it were with a soldered CPU, like a mobile CPU and a single PCIe Slot, I would buy a couple for sure!

I wish I owned a PowerMac G3 because I would TOTALLY TRY THIS! Awesome video ;)

ah ... the memories... NT was installed on all the PCs when i was in college

You know you HAVE to install Linux on there too so you can have a quad-boot Mac...

I'm thinking OS 9 didn't like the partitions because the disk was not partitioned by Mac OS. Apple had its own partitioning scheme separate from MBR on x86 and whatever scheme NT for PPC would have been using.

Great minds think alike MJD just made a vid on the same topic. Super cool love both vids. 🏆

I would have loved that loader back in the day.

"Software should never be running" Crowdstrike agrees

I have a 233mhz initial release Bondi Blue iMac G3 and I wish this would work on it just for the lols. Wish I still had the keyboard and mouse. It even has its original MacOS installation on it. Works properly too. The USB port actually works OK with older optical keyboard/mouse combos.

There's a fast way to get drives without Apple's firmware formatted on old Macintosh computers. Format them for PC first. If your drive is going to be HFS then format it as FAT16 on a PC. For HFS+ format it as FAT32. Connect up to a Macintosh and boot up with any DOS/PC support *disabled*. The Mac will complain about being unable to read the drive, do you want to initialize it? YES! In a few seconds you'll have the drive in HFS or HFS+ format without any 3rd party software or hacked Apple drive setup. I did this trick a lot in the 1990's.

The error message about "machine type" is interesting since you normally never see that, also poorly formatted with the odd line break. Typing this on my ARM-based Surface tablet which does an incredible job emulating Intel-based executables where needed.

I recall trying to install NT4 on my home machine back in the late 90s (doing a dual boot with 98). It required a lot of swapping out floppies, and just hoping that it would work. Windows 2000 got things right, though that won't run natively on a Macintosh

This video was completely unholy. I like it. But yeah, Windows NT has no business being on such an un-beige machine.

10:40 - I have one of the rare PowerPC IBM ThinkPads, and I use the 16-bit x86 compatibility layer for more software than native PPC. The latest web browser for NT-PPC is IE3, which is _TERRIBLE_ even by the standards of its day. So I run the 16-bit Windows 3.1 version of IE5. Likewise, the Windows 3.1 version of Microsoft Office runs just fine.

Genuinely thought this was a collab with MJD looking at the thumbnails and release time

If you can port Windows NT PPC to PPC mac, you can port it to wii and gamecube

This is a dream come true for me. I even have a Yosemite G3 of my very own to try this on.

All I know.... is that MattKC would be proud....

For running 32bit Windows software on RISC NT, there is a tool from Microsoft called wx86. It only ever got as far as a Technology Preview so its not on the NT4 CD and was only briefly available from Microsoft. They seem to have abandoned it when they dropped support for MIPS and PPC - probably no point keeping it around at that point given Alpha already had something that worked far better (FX!32). You can still find wx86 for PPC/MIPS/Alpha online though, and on PPC and MIPS its perhaps better than nothing.

"And I spelled it wrong" made me think of a Steve Jobs clip I just watched: "slash…F-it's a wonderful user interface"

damned fine, a new "alternate lifestyle" for my 24+ G3! you know, i still like the looks of it...

6:32 video: [PC humming] RU-vid: [Music]

Well that “90’s dream” is 30 years too late i guess🤣

Definitely want to try and get this running on the G4 Cube, despite the fact that it probably won't.

Wel, there is a DOSBox for Win 95, NT 3.51 and NT 4. Command prompt (and it is that, not really a dos prompt) is not suitable for gaming in any version of Windows (unless you boot 3.x/9x versions into DOS mode). Many games for WiN9x will also not work on NT, or contemporary software that deals with 3D graphics.

This is absolutly crazy my brother

And it was just updated for NT 3.51 support!

You and MJD both on the same day with the same idea... :)

im looking to aquier a power mac now to try this. cant wait tell windows 2000/xp gets working on this hardware.

So, what’s the difference between Myst VPN and a TOR Browser? Aren’t they both decentralised?

Could you mount the Hax CD image to a tiny partition on one of the hard drives? That way you can just hold Option and choose Hax partition to boot?

The person who made this hack is one of the greatest humans who ever lived.

If this was achieved back in the 90s then Stee Jobs would have exploded

I'm surprised Dark Forces ran as much as it did. NTVDM's CPU emulation must emulate more than just 16 bit instructions as Dark Forces is a 32 bit DOS game. AFAIK due to rights issues CPU emulation in NTVDM couldn't be included in other versions of NT so Modern 64bit Windows doesn't even include NTVDM. Even if there was a sound driver for the Mac, there wouldn't be any sound in Dark Forces as NTVDM for NT4 does not emulate any sound cards for DOS programs, you'd need a third party addon for that or a newer version of NT like Windows XP) No version of NT4 has official USB support. There are some third party usb drivers for x86 NT4 that add very limited device support. NT only got official USB support starting with WIN2K. NT4 was not plug and play compatible so a plug and play bus like USB is just not going to work.

Always wanted to be able to run Halo CE and Windows on an imac G3. But there isn't enough SDRAM on it. It's GPU can support up to 64MB but only has 16, and people tried upgrading the chips without getting it to boot.

NT Server of the PowerMac, NT Workstation on the iMac. You know you want to.

Pretty cool. Can you add even more OS's - Be/Haiku and Linux, maybe?

Primordial Bootcamp

my first PC was an apple that could boot between mac and DOS. no dual boot that would have been pretty cool for 1992, but yeah it was a pretty cool computer that steve jobs would have never condoned

You should try Soft Windows 32 like MJD did. Although it doesn’t seem great, it can get 32-bit applications to run on this version of NT and you could probably get those programs to run

i'm honestly not sure what's more cursed, the Mac version of Space Cadet pinball, or this. Though, the Mac version also runs on 68k, so there's that.

I really want to try this on one of my slot loading G3's but I feel like its not mature enough yet, But I'd love to see NT boot on one of those nuggets!

NT wasn’t compatible with a lot of 16-bit DOS/Windows software in general, so those programs might not have worked on a x86 install either.

NT4 and USB was "Stinky" at the best of times. 'Microsoft have made the commercial decision not to provide NT4 USB support - but some manufacturers provide support for specific USB devices on NT4.' is about right. Some Manufacturers supported and supplied drivers for specific devices on NT4, but "out the box" - nope. There's no stack available. So getting USB on a power pc mac working under NT is probably extremely difficult at best. My own experience of NT4 as a student, late 90's, was frustrating. 2000 was much nicer and DID have inbuilt USB support. My pc (P2 era) had the capability (1.1 ports) but no drivers and precious few devices. Uni was a bit meh about what you could install since they supplied the machines and controlled what was on the network. Great vid though :-) takes me back a bit. SP2 is installable... apparently.

Still more supported than Mac O.S 😂

USB does not exist in Windows NT4 x86 too, I believe this is the major caveat running it also in a Mac

10:50 - Now I'm going to have to see how many SPF Dark Forces gets on my ThinkPad 820! (With its 100 MHz PowerPC 603e.)

It’s cursed, but it’s beautiful!

IIRC Windows NT 4.0 didn't support USB on Intel either. Not until Windows 2000.

Thank you. I always wanted to to do this.

You could do this on the G4 Yikes too, which has solder points for ADB.

I miss those times, when IT was fun, not stupid things like today!

IIRC Windows NT on PPC is little-endian, while all Apple's PPC operating systems are big-endian, so do Apple's firmware. I remember that changing the endianness in Apple's Open Firmware will brick the hardware. If this ARC bootloader can change the system to little-endian, it could also be used for running Linux compiled as little-endian, which may fix the glitches while using ATI graphics under X and big-endian OS, which plagued the PowerPC Macs.🧐

> Motorola SOFT WINDOWS 32 for PPC < Probably best to install NT4 SP2 for PPC first - sadly no SP3 Now you have a PPC Mac running NT4 that can run everything* x86 NT4 SP2 can run. :-D *Ok, dog slow. Maybe upgrade the CPU - God alone knows what would happen with a dual PPC. ;-) *Ok, ok. 32bit apps with a 16bit installer are going to be a PITA - there are workarounds... ...one being to copy the install folder from a contemporary x86 machine, real or emulated. *ok, ok, ok. There's no SP3 for PPC, but you may be able to spoof it with a RegEdit... ...which may work if the software is being grumpy, or just hard-lock the machine. *Audio, USB? Nope. For now... PS Voodoo 2? Probably not.

Some of the old clickteam game engines were 16bit windows compatible, I'd like to see how they run 😆

this is beatutiful. finally a mac that doesnt suck.
