The 90’s? Locked bootloaders would’ve meant people woukdve simply bought different machines without a locked bootloader.
See the IBM/Phoenix BIOS war - it’s essentially the same thing. IBM didn’t want to license their BIOS to everyone, so Phoenix reverse engineered it. If I remember right, IBM was trying to lock everyone to using their OS.
IBM built the original PC from off the shelf components and for some reason negotiated a non-exclusive license for MS-DOS with Microsoft. The only thing in the PC they held a copyright on was the BIOS ROM. A few companies tried making clones, IIRC Eagle Computer just brazenly dumped the IBM BIOS and used that and got sued out of existence. I believe it was Compaq that developed their own MS-DOS compatible BIOS from scratch that did not infringe so IBM had no case to sue. IBM got a competitor they didn’t want, and the PC became a 40 year platform.
This! Manufacturers were trying to lock people into their systems, just by different means. Reverse engineering a piece of low-level software (BIOS) so that you could run high-level software written for that machine architecture on different hardware was the main battle of the day.

Thanks, it’s been a while.
its good to remember computers were used mostly by the computer people back then.
now with layman using theses devices en masse, things are a bit different. they dont need the nerds ro have a successful product anymore.

The ’90s*
Made me think of the first season of Halt and Catch Fire.
Liked the first season but worry the second is crap so haven’t watched it.
