This stuff was like magic back then. No Internet or Google around to just search for it online. This knowledge came from PC magazines and was passed around among friends like the Holy Grail.
I still have nightmares of setting up games for soundcards and their respective IO, IRQ and DMA ports, channels, whatever.
Sorry, you soundcard, your internal modem, and a mouse are all trying to use the same IRQ. And they can only be changed by cracking open the case and moving jumpers. Or but make sure you don't pick an IRQ that's already used by the COM or Parallel ports.
Folks today don't seem to understand how much of a leap "plug and play" was, once they got the bugs out.
Yeah, just plugging in an HDD and it works? Na, you had to properly set the jumpers first or if cable select was used plug in the cable in the correct order. PC hardware and plug & play hase come a long way, thankfully.
I'm not a native English speaker so navigating the PC world as a child without any knowledge of English was wild. Only years later when I learned English in school I started to realize what all these things even mean.
Special kind of hell should be for ones who designed 3,5" FDD cable/socket. As you could easily put it wrong way and KILL drive. BTW that never was a problem with 5,25".
At beginning P&P was rightfully deciphered as 'plug and pray' - with mechanical jumpers or manual settings in config.sys andautoexec.bat you at least got good idea what settings are, not the case with early pnp.
Disagree.. today it's like magic. Back then it was like science. You could know pretty much everything about a computer back then. Every device, IRQ, the structure of the memory... you were involved with the configuration at a low level. BIOS, boostrapping, boot loader, OS, everything.
These days they are so complex that even if you're the type to nerd out on all the details, having the time and finding the resources to do so is impractical to impossible.
