I would love to. Sadly though, my DSL internet is crap. Upload speeds means it would be impractical to attempt uploading large things like this. However I am willing help you through setting it up on your end if you have your own VMWare image of Tiger? I use VMWare mostly because it's what I happen to already have installed. I don't know what other things can do this. I suppose anything that is able to expose network access to the guest OS like VMWare can would do.
The serial key I found that worked came from the Macintosh repository version of MacOS X Tiger 10.4.7 (server edition). Found here:
https://www.macintoshrepository.org/13602-mac-os-x-server-10-4-7-tiger-That version is a universal binary so it can run on PPC and Intel machines. (Really the only version of Tiger still easily accessible today that can run on Intel machines) Somehow didn't notice the serial key tucked just above the download link and tried to use the keys provided over at the Macintosh Garden copy which were time limited codes which wouldn't work after install.
As for virtualizing this on PCs, VMWare doesn't normally allow you to run MacOS X stuff on PCs though. But you can use something "Mac OS X Unlocker" found on InsanelyMac website. (Sufficient googling should get you to that one. I have the older 1.x version though which took me quite awhile to find. I can provide that if you want to use VMWare 10.0 or older).
As for the MacOS 9 image. I haven't found out how to make my own NBIs, but the one Apple provides works:
https://support.apple.com/kb/DL1192?locale=es_ENDownload that, then mount the DMG file. Open the PKG installer in the langage folder of your choice. It will install the NetBoot image to the proper location where it will show up in both Server Admin's NetBoot configuration and in BootMania. I had to use BootMania still though because for some reason Tiger's Admin tool won't let me use DHCP which is required for my older G3 iMac tray loader. But if you have newer machines that support NetBoot over AFP then that would work as is.
Oh and the NBI file that NetBoot9 image from Apple installs turns out to be a folder in disguise. I accidentally managed to expose it as a normal folder again by attempting to set default open with to Disc Utility then tried to use Finder to open with instead. It then become a folder. Though perhaps there's other proper ways to do this, but for me that worked. The img files inside can be mounted with Disk Utility and you can modify the contents (I'd recommend getting rid of the Multi-User Support extension first. That gets rid of the login requirement and net booted clients will go straight to MacOS 9 finder)
There's a PLIST file that seems to actually define what IMG files the NBI contains and the Mac OS ROM to send to the clients. Seems rather straight forward to create new ones. The file seems simple enough.
Anyways you can PM me more about this. Having to enter captchas and question challenges on every post is pretty annoying. (I suppose that goes away after you hit a certain post threshold or something.
)
EDIT:
Oh and be sure to disable AFP/NetBoot service in Server Admin if you intend to use BootMania, else BootMania will complain about these services already being active and will refuse to start)
EDIT2:
Oh another thing. If you don't have media to burn the DMG file to. Booting the Tiger installer on VMWare can be a bit of a chore. I recall trying to simply mount it as a CD drive as an ISO, but VMWare wouldn't mount it right..wouldn't boot it.
I found a pre made 10.6 server VMWare disk. From where I created a new ISO image with PowerISO, tucked the DMG file of Tiger into it. Then booted up that 10.6 install with it mounted after mounting a second blank "hard-drive" image. Then opened the DMG file and mounted it. Then used Disk Utility to "copy" it over the new hard-drive image I mounted with VMWare. (via the Restore tab in Disk Utility).
This was one ***backwards way of doing what I wanted, but lol that worked. I could then boot this Tiger installer harddisk image I made and install new instances of Tiger onto fresh hard-disk images.
EDIT3:
Ok I exported the VMWare machine toa a OVF file. (Open VirtualMachine Format). This resulted in 3 files. A mf file, a OVF file, and a compressed copy of the VMDF disk image.
The ovf file can be imported back into VMWare via the Open dialog when going to open a existing Virtual machine. Though perhaps other VM software could possibly import this assuming you can run Mac OS X Tiger in things other then VMWare (on a PC anyways). With everything zipped up, the resulting file is about 4.7GB. So not as large as expected. I could possibly have this uploaded. But it will take probably 12 hours to upload. So would have to do it overnight.
So I redid the virtual machine with a version of Tiger where I used more "generic" login details (as the first go around, I used my name and a personal password to setup the user account) so that it would be suitable for sharing. I can upload this somewhere and PM it to you tomorrow. This would probably help get you setup a bit faster as you'd only have to worry about setting up VMWare/Other virtual machine software on your end.
