What a trip down memory lane. This was my bedtime reading when I was a kid. It was a great tool and endlessly fascinating.
A part of me wishes DOS was still relevant.
- lockhouse 4y agoYou can do a surprising amount of "modern" computing in FreeDOS. https://arstechnica.com/information-technology/2021/07/dos-boot-ars-spends-a-day-working-in-freedos/ https://arstechnica.com/information-technology/2021/07/dos-b... It also makes a great boot loader for hobby OSes. Both Windows and Novell Netware worked in this way.
- mycall 4y agoCan FreeDOS IRQ into Windows 10 or API-level calls? That would be interesting.
- vetinari 4y agoYou probably meant int into windows syscalls. IRQs are hardware-generated interrupts, when hardware demands attention. And the syscall instruction, as the fast int replacement, is not recognized at all in real or vm86 modes. In the end, it depends on the environment that you use to run the FreeDOS, whether it forwards them or not. Note that windows does not provide binary compatibility at syscall level, only at ntdll level, which would be useless outside currently running windows, so it could be useless even if it was forwarded.
- xtracto 4y agoYou just brought me great memories of me and my dad setting up those hand-operated black and white logitech scanners. Having to connect custom ISA cards and manually configuring IRQ ports and DMA channels in the cards. Normally done through jumpers... and when we got a card with Dip Switches!! it was THE FUTURE. Great times!
- kjs3 4y agoThere's still a ton of DOS running embedded/industrial applications. Quite relevant.
