Yeah, that might be a problem. Hopefully someone (AMD, RISC-V, Intel if resurrected ) will end NVIDIA close source era.
Hypnotizing defrag was a MUST. If it failed and screwed up your 20 MB of data hard drive there was no full backup option - the few floppy disks you had were reserved for sharing games.LOL -- I used to run defrag all the time... because I was so annoyed at how darn slow my Windows O/S was getting.
And ya I would stare at the "little boxes" changing color just like that screen shot.
So... I wasn't the (ONLY ONE) doing that !? Glad I am in the "echo chamber"![]()
Also remember the intricate multi-option config.sys and autoexec.bat to either highsys and freemem(ory) for Doom2 or load a bunch of bloat (cca 300kB). DosNavigator and unRAR was a savior...not to diss Volkov Commander but DosNavigator had pretty neat Tetris inside too.
