- Yeah, but I don't see any sensible reason for not making 386+387 the
- minimum requirement - the differences between a 486 and a system with 386+387
- are not exactly major, from a programming point of view.
-
- No, I would guess that something else is going one here. This actually
- reminded me of something - what seems a long time ago, some programs checked
- the PC ROM, and refused to run, unless they found an IBM copyright message
- there. Of course, other BIOS manufacturers found a way around this - one
- BIOS even contains the text "Some software expects to find Copyright IBM here"
- with "Copyright IBM located in exactly the right position"
-
- Well, the only benefit I can see for making the software 486-specific is that
- it would help selling '486 processors. And who would benefit .... right,
- Intel.
-
- Letting the program to run on only true 486's does not help the end-user much,
- but it is sure to hurt Cyrix and AMD....time to sell their stock :-) I guess.
-
- Now, I am not suggesting that Intel may actually have paid for having them
- make the software '486 specific...it wouldn't be nice to say that, but........
