I've recently heard two rumors on this subject: first, that OS/2 2.0 will be the last version of OS/2 that will support machines based on the 80286 processor. The second rumor was that OS/2 2.0 will be the first version that WILL NOT support the 80286. Which is true? Neither? Anyone know? ++++ Bob Hodge ++++++++++++++++++++++++++++++++++++++++++++ + "The art of living is more like wrestling than dancing." + + - Marcus Aurelius (121 - 180 a.d.) + +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

OS2 2.0 will NOT support the 80286. (Personally, I feel it was a mistake to support it in the first place, but that's only my opinion). It will be backward compatible with code written with 1.x by supporting a 16:16 addressing mode of some sort. OS2 2.0 will use a straight 32 bit addressing scheme. I'm shakey on all the details of this. Rumors to the contrary (which appeared in PC Week) have been corrected/retracted in a recent issue. -- uunet!dialogic!gerry | "Even a dead plant turns | Dialogic Corporation OR | over a new leaf | 300 Littleton Rd gerry@dialogic.UUCP | when the wind blows." | Parsippany, NJ 07054 | | (201)334-8450

OS/2, Version 2.0 will require a 386 or 486 based computer. This has been announced and is public knowledge. No statement has been made about any 'last version' for the 286, all we have said is that Version 2.0 requires a 386/486 because it uses three features which do not exist on the 286. Namely: Virtual x86 support, for Multiple Virtual Dos machines Paged Memory, for improved Virtual Memory performance 32-bit 'flat' adressing, for improved portability of code, simplicity and speed. The market is clearly asking us to provide features which require a 386/486 and that is where we are concentrating our efforts at present. We will revisit the need for further 286 versions of os2, but os2 2.0 is the most important at this time. OS/2, 1.21 which is shipping very shortly from all major PC vendors, is a very rich, stable and complete 286 operating system with the majority of printers in use today supported with drivers which support downloadable fonts, font cartridges and other model-unique features and they have been proved to work with the 53 Presentation Manager applications available today. OS/2 1.21 will remain useful on 286 computers after 2.0 is available for 386/486 machines. Pre-release versions of OS/2 2.0, for developers of 32-bit OS/2 applications, are available today. This month we are shipping a major update which provides a very stable platform for developers - stable enough for our own developers to use to develop os2 2.0 itself.

(actually Reston, VA) the Microsoft people said you can now purchase the OS/2 2.0 SDK pre-release now which comes with a pre-release of OS/2 2.0. They also announced that OS/2 WILL SUPPORT the following. Applications written for all previous final releases of OS/2. multitasking of up to 16 DOS applications. binary compatibility for Windows 3.0 applications. The last item is very nice. Now if a user wants to migrate from DOS/Windows, the Windows apps already owned can simply be run as OS/2/PM applications right out of the box with no modification. These apps may not run as efficeintly as PM apps or take full advantage of the OS/2-PM resources, but they should be comparable to running them under Windows. We'll see!?!
