The included SSW 7.5.3 is perhaps the easiest system of this era I've had to install. Usually I've installed from those multiple parts for 7.5.3 from Apple - This was totally painless to install in comparison, using this CD. Hense, it still good to run on SheepShaver.
However, this CD doesn't boot at all on Basilisk II, because it were based on Power Macintosh PCI system software.

Mac OS 9.1 and later could not boot successfully on SheepShaver because it lacks memory management unit (MMU). However, there are some ways to get 9.1 working on SheepShaver by hacking the System file or replacing System file from Mac OS 9.0.4 and changing version number to 9.1 using ResEdit
, but this may result system instability.
If you are running PowerBook 3400c, use the update without updating hard disk drivers.
For PowerBook 1400s, Password Security is not supported.
For 20th Anniversary Mac, disable Virtual Memory.
For Power Macintosh 6100/7100/8100, you need to install from the CD version, updating from 9.0.x is not supported.
Also, for PowerMac 61/71/8100/9150 with a third-party accelerator card will not install Mac OS 9.1.

For PowerBook G3 series Macintosh, it appears to be suitable for installing onto SheepShaver, too. It boots, installs and runs fine on my SheepShaver (with Old World ROM) setup.
