Mac OS from scratch, on MAME 0.232+ (or a recent Git pull). (post 1/2)

Prereqs: the Apple Legacy Recovery CD-ROM, which you can get from Macintosh Garden. WARNING: Internet Archive has a version of the CD which does not work properly - it boots, but the file association with the .scr scripts doesn't work.

First, create a hard disk image. I'll give instructions for one that's around 500 MB, but you can go up to at least 1 GB without MacOS getting upset.
For an uncompressed CHD, enter chdman createhd -c none -chs 1023,63,16 -o myhdd.chd. If you're on Linux, BSD, or modern macOS, you can easily create a non-CHD raw image with dd if=/dev/zero of=myhdd.hdv bs=1000000 count=500.

Second, start MAME with the hard disk image you just created and the Legacy Recovery CD-ROM mounted on the Mac IIci driver: mame maciici -ramsize 8M -hard1 myhdd.chd -cdrom "Apple Legacy Recovery Oct 1999.iso" (use myhdd.hdv instead if you chose that route to create the image).

The first time you boot the CD on most machines, you will get the smiley Mac and possibly even Welcome to Macintosh and then it will reboot. Unfortunately the CD also ejects itself at this time so the system will reboot and you'll get the disk with the flashing ? symbol. When that happens, just quit MAME and restart with the same options (up-arrow command line history is your friend here).

The system will start up and you'll see a Finder desktop like this:


Double-click the "Legacy Recovery" icon:


And then double-click "Disk Utilities" and then "Formatting Software":


Next double-click "Drive Setup 1.5":


Click your hard disk image, which will show as "<not initialized>" and then click the "Initialize.." button:


When this warning comes up, you can pick "Custom Setup..." if you know what you're doing and want to partition the hard disk in some special way, or just click "Initialize" to get a single partition the full size of the disk:


You should get this success:

MacOS from scratch (post 2/2)

Select File -> Quit to exit Drive Setup, and close the "Formatting Software" and "Disk Utilities" windows.


Double-click the "Mac OS" folder and then the folder for the System version you wish to install. I chose System 7.1.1 here as a good choice - it's reasonably up-to-date, but doesn't use a ton of RAM like 7.5, and runs all the way back to the Macintosh Plus. (If you are unsure what versions will work on a particular model, double-click the "System Software by CPU" folder and then navigate to the model you'd like to run).


Double-click the "Net Install.scr" file to launch Disk Copy and mount all of the installation disk images.


Click "Agree". After a few moments the installer will launch. This will look different depending on the version you pick, my screenshots here are for System 7.1.1.


Click Ok to get to the main installer screen (for some versions you may go directly here):


The defaults are usually OK. Make sure it's "Macintosh Family system software" or "System Software for all Macs" or something like that (the phrasing differs per System version) to ensure the resulting hard disk can boot on any supported Mac.


Once the installer is done, you should see this success:


Choose "Quit", and then choose "Shut Down" from the "Special" menu to cleanly shut down the system:


Quit MAME and then restart it without the Legacy Recovery CD-ROM mounted. It should boot up into your installed System version:

Installing OS/2 Warp 3 in pc9821ap2

Notes at the time of writing:
- Bleeding edge or upcoming MAME 0.272.
- Doesn't work in plain pc9821 (kernel panic during install), do not bother in anything beyond pc9821ce2 (will make use of PCI features, assuming you even get there)

1. Enable IDE BIOS in Machine Configuration thru TAB menu (step eventually to be removed)

2. Create a chdman HDD,
3. Startup the machine

4. You will be greeted with an █ █ OS/2 prompt then this, which just means to swap os/2 warp 3 with Disk 1 in Drive A then strike enter key


5. Loading from floppy drive, with an extra more laconical "loading" screen afterwards


6. Once done, OS/2 will ask to insert installation floppy again, and CD-Rom if it isn't already


7. Ask for user to select between Basic or Advanced configuration. The HDD partition is currently unformatted so need to choose Advanced here


8. Select 1 for formatting the HDD with one contiguous partition.


9. Partitioning complete, remove and reinsert the Install Disk media (?), then at "SYSTEM SHUTDOWN" soft reset the machine


10. Now redo step 4, until you reach this, select 1 if one partition is used


11. Asks you if you want the normal PC-98 letter scheme (1, A: will be HDD) or the more canonical DOS/V schema (where A: is floppy and C: is HDD)


12. install phase 1


13. At the end of it, will ask for removing floppy drive then strike enter -> "SYSTEM SHUTDOWN" -> soft reset


At this point once rebooted OS/2 will ask for the usual device select and what OS parts to install, at the time of this writing those screens are broken so delaying this (trivial) part for later.

Installing OS/2 Warp 3 in pc9821ap2 (part 2).
Press ESC to return back to a previous step.

14. Device select.
The ones on top row are Code Page and JIS arrangement
middle row is serial support (yes), keyboard (98 keys), graphic adapter (PEGC at 256 colors)
Bottom row is APM (none), PCMCIA (no), CD-ROM, Printer (do not install default printer), Music adapter (PC-9821 A Mate), SCSI (no).
ETA: at current time there's a bug that will list CD-ROM as その他 (others), eventually leading to the media missing when installed. Going in CD select and select PC CD-101 should fix this inconvenient.



Most of the stuff not automatically detected isn't supported at the time of this writing, so just click on bottom left button to go on.

15. OS component select. Bottom right box is available space (top) vs. required (bottom).
Pressing (R) button will go "Recommended", which gets rid of most fonts packages and マルチメディアのソフトウェアのサポート (Multimedia Software Support), (A) button will install everything. Going R then re-enabling the extra Multimedia pack will trim down installation to 38-ish MB.
Press (I) button to install.


16. "Expansion Options". Not sure what this setting does, the other two are always greyed out (open preference then modem service options?). Press left button to continue.


17. Ready to be greeted with the OS/2 install progress bar.


18. Once done, it will prompt to this screen, that suggests to change system defaults. Press left button to go "End" and soft reset.




19. Finally ready to use the OS

Power Macintosh setup in MAME git master as of this posting. NOTE: the driver's not yet promoted to working for several good reasons, so while this procedure works, running other software and System versions on the driver may not have great results. Also, this assumes you have the mac_cd software list items.

To start, create a blank hard disk file with your favorite method. On Linux, FreeBSD, or macOS, this command will make a blank ~500 megabyte image named "powermac.hdv":
dd if=/dev/zero of=powermac.hdv bs=1024 count=524288

Start MAME like this:
./mame pmac6100 -hard1 powermac.hdv pwrmaccd

After boot up it should look like this:


Double click the Utilities folder and then double click HD SC Setup.


Click Initialize and then "Init" when the warning comes up. You'll get the spinning beachball cursor for several minutes so now's a good time to turn throttle off in MAME (switch to MAME keyboard mode and F10) and go watch a YouTube video or something.

When it beeps that it's done, name the hard disk. I used "Power Mac HD", but the name doesn't matter.


After that, click the Partition button and then click the Custom button in the window that appears.


Click the small partition you just created (here called "Power Mac HD") and then click the Remove button and accept the warning.

Next click immediately below the "Mac Driver" partition and drag down to the bottom so you get a partition that takes up the entire disk.


In the window that comes up, select "Macintosh Volume", and if the size displayed in the edit box isn't the full amount shown for "Maximum", feel free to change it to use the whole disk. Click Ok when you're done, then Done, and then Quit.


Close the Utilities window and double-click "Install System Software" and click OK in the introduction window that appears.

Click "Install" to get the Easy Install option, which will do what you need. The installation will begin.


When the installation is done, click "Quit".


Drag the "Utilities" folder to the icon for the hard disk you partitioned and it will copy those utilities to the drive image. Do the same with the "Apple Extras" folder.


Click the "Special" menu and select "Restart", which will automatically eject the install CD and start up from your newly installed hard disk image. That's it.

Installing Workbench 1.3 to HDD using the A590 HDD controller

1. Create CHD

Right now only XT-IDE type drives work, and the jumper that selects between 20 and 40 MB drives isn't implemented, so we create a 20 MB drive (template 6 works fine):


2. Attach A590 with drive and boot from the A590 installation disk

Any A590 disk will work, they only differ in the supported drives for low level format (and we don't need any low level format).


3. Start HDToolBox and configure drive

After a while, you should see the Workbench screen and the disk icons. Double click the A590 setup disk icon and start HDToolBox. You should get this screen:



Select "Change Drive Type" and "Define New Type". Adjust the values to the drive. For template 6 we can use those values:



Click Okay, then Okay again to return to the main menu.

4. Partition drive

Click "Partition Drive" and change the partition device name to "DH0". The rest of the values should be fine.



5. Save changes

Click on "Save Changes to Drive" then "Exit". Reboot with Ctrl-Amiga-Amiga so that the Amiga will detect your new partition.

6. Format drive and install Workbench to HDD

After Workbench has booted from floppy again, open the A590 setup disk and start "FormatHD". Answer "y" and the format should start:



After a while, it asks you to insert your Workbench 1.3 disk. You can use "wb133_uk:workbench" from the softlist for example. It should start copying the files to HDD and also ask you for the Extras disk (you can use "wb133_uk:extras" here).

7. Boot from HDD

Once everything has been copied you can remove all floppy disks and reboot with Ctrl-Amiga-Amiga. The Amiga should boot from HDD:



Note: Copying data from floppies is unstable under Kickstart 1.3 and earlier. This is because it uses the blitter to decode MFM data and there is a bug somewhere that causes it to sometimes return incorrect data. If that happens, you can try to remove the floppy and then insert it again. Usually it should start working. This isn't an issue under Kickstart 2.0 and better because they switched to decoding MFM data using the CPU.

Installing Apple Rhapsody DR1 on pcipc (Part 1/2)

1. Prepare an HDD with chdman. Using 1 GB template here, note it definitely won't work with some threshold (i.e. 8 GB will detect 16 MB on partition disk manager), needs a minimum of 270 MB.

2. Run pcipc with rhapboot.img in -flop1, the DR1.iso in -cdrom and the newly created -hard

3. boot disk by just return key, Type 1 for the English (disk shouldn't support anything else), Type 1 to prepare to install Rhapsody


4. Asks for Rhapsody Device Drivers, swap -flop1 with rhapdev.img, once another loading it will ask to install SCSI/IDE controller, cycle with 7 until you reach "Primary/Secondary(Dual) EIDE and ATAPI Device Controllers" then type 5


5. Will ask for another SCSI adapter to use for the HDD, select again Dual EIDE by cycling with 7 and 5. Type 1 afterwards for not loading any other driver.


6. We are now in Rhapsody Mach OS. If all of above is done correctly it should show the option for installing Rhapsody on an HDD.




7. Type 1, 4 times overall, to install to the whole disk. Optionally user can partition the disk for multiboot from here by following prompts, afterwards it will start copy the files on disk.


8. Once done remove rhapdev.img from flop1 and press Return, pcipc will reboot after a bit.


9. Once back we are greeted with the Rhapsody splash screen, note that this phase will take a bit to complete (eventually indicated by a progress bar).


10. Final touches: we need at least a PCI video card driver. Click on the monitor icon ...


11. ... , select either of the detected drivers ...

Apple Rhapsody DR1 Part 2/2

12. ... and select a suitable video mode. Warning: selecting 640x480x8 will crash later with a Workspace Manager Error, choosing 1024x768x15 to stay safe here:


13. Click done then Save, after a while will prompt for selecting components to install, click on Install afterwards. Wait it copies then reboot when prompted.




14. After it loads again, just select English and USA keyboard (afaik the only thing this supports), confirm with Ok at the Alert:


15. at this point the OS should be ready to go, if you choose a wrong color depth then it will crash at this point with a Workspace Manager Error, rinse and repeat the whole installation if that happens
