- No. Let me speak very slowly so you'll understand. What I am
- saying is that with very little amount of pure 32 bit 486 code out there,
- and with Cyrix aiming for the entry level desktop market, thorough
- 32 bit testing would be very difficult and probably with little value
- added. Think of it this way: what are you going to spend the money to
- test? DOS, or a Unix flavor, from say SCO or Sun?
-
- If you are trying to sell something to the general PC market, working
- with DOS/Windows 3.x/DOS application software is going to be infinitely
- more important to you than getting Sun Solaris going. (As an aside,
- does anybody know of SCO Unix or Sun Solaris require a 486? I'm under
- the impression that they only require a 386.) I'm not saying they
- *didn't* test anything that was 32 bit, but I doubt they could have
- possibly tested much that was written for the 486 with its changes to
- the supervisor mode/exception handling/etc. because *there* *was* *not*
- *much* *out* *there* that a general PC user would use.
