Yes, I think it's OK. :)
Anyway, I have to install FreeDOS but I see the requirement is for an Intel CPU. My problem at the moment is finding an Intel mobo that supports Legacy BIOS or Compatibility Support Mode. So, is the requirement for Intel CPU a hard and fast rule or is it just that this is what it was written for?
It's not just the CPU - the supporting BIOS or UEFI in legacy mode is needed too, see: https://www.freedos.org/download/ but see also below.
Will FreeDOS work on AMD CPUs?
Not without something like an emulator or a virtual machine. For example I routinely run packaged software which was compiled for DOS on more or less all of the Raspberry Pi boards, using the DOSBox DOS emluator. It occasionally crashes when doing a compilation, but as that job used to take 24 hours or so on an 8086 box and now takes a minute or so on a Pi4B I'm not too worried about it. I've never seen it crash when actually running the resulting compiled program. There are other versions of DOSBox and other ways to emulate, but it works well enough for me now that I've never bothered to try them. I believe you could also use the same tricks to run on a UEFI Intel board which does not provide BIOS compatibility features, but I have never done that myself. I'm sure others here can help with that. -- 73, Ged. _______________________________________________ Freedos-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-user
