I also learned thar that Mac OS or "System" is comparable to the Windows 9x line of Windows,
while OS X (or now macOS) is pretty much like the OS/2 or Windows NT line.
Back in time, you had to boot into old Mac OS (OS 9) whenever you had to perform upgrades,
had to run system diagnostics programs, boot from an USB pendrive of an USB port (on a clamshell, you can do that from OS 9!)
This is wrong. Mac OS X has its own set of diagnostics programs, and some third party system utilities included the ability to fix both Mac OS 9 and Mac OS X boot volumes
Oh come on, don't be so picky about these details please. Relax. 😀
What I was refereing to was the time period between old world Macs and new world Macs (pre G4).
To name an example, the upgrade for my '98 iMac (tray loading) required a firmware update that was available for OS 8/9 only.
Mac OS 9 has a lot of relationship to Windows 98SE. Both are quirky, have single core support, are single user OSes, can use old ROM code, just like Windows 98 can use DOS drivers or BIOS code. Both allow manipulating RAM and ROM space, allow direct port access, etc.
I would even go so far as to compare System 7 to Windows 3.1 and System 7.5 to WfW 3.11.
They share so many things, like then new networking features, True type fonts, colour screens/high resolutions,
accelerated graphics and so on.
Speaking of the USB pen drive boot.. I guess you missed what I was refering to.
Old Clamshells and iMacs did not officially support USB boot yet, only boot via internal CD (they hadn't got firewire ports yet)
However, it was possible to boot via USB unofficially by using the start-up panel in Mac OS 9's Finder.
(The code was in their Open Firmware, but it was not meant to be used at the time.)
In contrast, Mac OS X didn't now allow choosing an USB drive for booting on that very same hardware.
Edit: Never mind.. Hope what I wrote didn''t come over too -uhm- offensive. 😅
