... or creating several boot configurations, tailored for DOOM, file transfer over COM ports, development work...
I did my own boot menu to select the configuration I wanted and then it booted the PC with my changes. All in a nice .BAT file!

Eddy talked about DOS in the thread below, so let me throw some obligatory nostalgia at you. :) And for youngsters, you'll never know that satisfaction feeling of successfully extending RAM usage for Doom to play (by modifying autoexec.bat) or resolve that IRQ confilct while tuning your brand new Soundblaster 16 :-D
that's pro. i only managed to play tie fighter after using memmaker :)

Those were the days...then I got a cold shower when I tried to revive an SGI O2...PROMs. Firmwares, bootloaders... Then I achieved Nirvana when I realized the games I compiled for the Nintendo DSi were compiled with the OS in them (Or rather the game was the operating system)

Indeed - I can remember the look of my father when I bought a second hard drive and installed it as the main, and had to move a jumper on the former main to make it as slave drive. I think he was a bit nervous, the thingies were quite expensive back then, and there was no tutorial youtube videos to back me up that I was not doing voodoo. (only a BBS text file with instructions, but that would have taken too long an explanation).

Really ? I did not know this about the Nintendo OS. "The game was the operating system" : this opens up so many possbilities *stars in the eyes*

And you could brick your computer by a single mistake in autoexec.bat. And learned a hard lessons with
delete t*.jpg /s -ymistyped asdelete *.jpg /s -y:~ Who needs pictures anyway ? :-DOn a PDP/11 running RSTS/E we had PIP PIP had an ability to Delete files, and entire accounts. On a DEV system, with a Physical Terminal SWITCH, someone switched my terminal to production, then cleared the screen. Did not put it back on DEV. I had gotten up, confirmed what I was supposed to delete... And I ended up deleting PRODUCTION FILES. A LOT of production files. We later added system BRANDING, etc. But after it happened to 2 other people. I actually went into the PRODUCTION systems, and PATCHED the operating system so the command syntax was DIFFERENT, and the normal DELETE parameter was replaced with the word ZAP It never happened again... LOL

New sound card, new RAM, new graphics, new mice, new motherboard, new PSU, new HDD, new CD ... :laugh:

How many people remember the days of repeatedly testing and tweaking your compiles to get everything to run in 320k of RAM or less? Loading page files into extended RAM was allowed, but we wouldn't send anything out the door that took more than 320k to load. ---------- Money makes the world go round ... but documentation moves the money.

That is why the compiler/linker supported “overlays”. Predecessor to DLL swapping to let the core of your program sit in 200KB and swap in other chunks to the left over 120 KB. Thank you linker! Of course your fixed/static/data segment memory could still not exceed 64 KB, ever!

And I'll bet these young whippersnappers have never had to low-level format their hard drive. DEBUG: G=C800:5
If you think 'goto' is evil, try writing an Assembly program without JMP.

MFM Drive? Use a RLL-Controller, DEBUG G=C800:6 an gain about 40% space on the same harddisk. OK, the defect map does not match anymore, but no risk, no fun :-D
