Is there any way to get this original os working on a new machine? Obviously it won't be very useable, but I want to try it our for interest's sake. Or, are there any emulators that will run this? Thanks, Jeff.

I think you're out of luck. I remember it will run only on 'special' ibm hardware like the PS/1 machines. You may check the readme or the manual for more information.

You do not need special IBM hardware to run OS/2 v1.0. You need a standard 286 system with 2MB's of RAM and a 10MB Hard Drive (Min).

Actually, I tried to install this OS on Bochs for Windows, but the emulator kept crashing

I managed to get it running on a 486-100 with 16 MB ram and a 120 meg HD with a 32 mb partition. What I did was disable the external cache during install. It installed just fine. After the install I re-enabled the external cache and it was still going strong. As for a modern computer you might try to disable the internal and external caches. Just a suggestion. FrankG

I just hound this about Bochs - old version and I haven't tried it yet. I have fond memories of running OS/2 in 1994 and have been keen to try it. At the moment, like Rkix, it won't even boot. Hope this helps. --Evan FROM: Bryce DenneyDATE: 06/11/2002 14:40:50SUBJECT: [Bochs-developers] Running OS/2 in BOCHS Diego Henriquez sent me a description of how to get OS/2 going in Bochs. He attached a version of the Bochs sources based on version 1.2.1 which he modified to make it run OS/2. The file is on the web now at http://bochs.sourceforge.net/tmp/bochs-1.2.1-henriquez-os2.zip Some of the problems Diego describes have been fixed since 1.2.1, but it sounds like he fixed some other things that I hadn't heard of before. Thanks!

I meant to send this file for a very long time but I been busy at work and at home, I don't even have time to follow what's going on on the bochs project. Anyway here is attached BOCHS121.ZIP, which is bochs ver 1.2.1 with source and the executible. Prepare OS/2 to run under bochs: To run OS/2 under bochs, you will have to create an installed os2 image. To do this, you'll have to install OS/2 in a real computer with a hard disk formated in FAT, OS/2 under bochs can't boot to HPFS partition because of PIC bugs, you can do this in two ways. Method 1: for this example I created disk image of 130 MB with the following dimensions. diskc: file=os2hdsk.dsk, cyl=936, heads=16, spt=17 boot bochs with the first two installable diskettes, go to the command prompt, run FDISK and create partition, format harddisk in FAT, run SYSINSTX C: from drive A:, this will make hard drive bootable to OS/2. Now on the real computer with OS/2 installed, boot to command prompt, take off all files attributes, specially Hiddend and System attributes. Backup all files from the real pc to floppy and restore them to the bochs pc. HINT: I did it this way, booted the real pc with DOS, using PKZIP.exe and PKUNZIP.EXE, I ran this this command PKZIP -arPex& a:os2 c:\*.*, Then boot bochs with DOS and restore files with the following command PKUNZIP -do a:os2 c:\. Restored all files, edit the CONFIG.SYS and change the following lines, BASEDEV=IBM1FLPY.ADD to BASEDEV=IBM1FLPY.ADD /V -> you'll need /V because of vga emulation problems BASEDEV=IBM1S506.ADD to BASEDEV=IBM1S506.ADD /A:0 /U:1 /ATAPI /V all this option is to make the CDROM work under the emulation. add this line BASEDEV=IBMIDECD.FLT this will make the cdrom work under OS/2, save the CONFIG file and reboot bochs. you might need to retore os2.ini and os2system.ini from backup. Method 2: Install OS/2 on real PC, create an image of the harddisk of the real PC, then edit the CONFIG.SYS file to look like above, the reboot bochs to start from drive C: to run OS/2. What runs and what doen't runs: DOS and Windows apps under OS/2 does not run, OS/2 initial installation doesn't run either. All 32bit OS/2 apps run fine, well all the one that I tested. Patches to BOCHS to make OS/2 run: First, the calculation for the limit in access.cc was fixed, this enable me to load the kernal into memory. Second, the floppy controller. I added a Global memory named GblMem to keep track to the floppy status at memory location 40:3E. OS/2 floppy device driver, IBM1FLPY.ADD, check the status of the floppy after each floppy command. Added the command for read and write, OS/2 uses different command for reading and writting. One thing I couldn't get to work was to use 2.88MB flopplies, becuse OS/2 use a command to switch the floppy controller to perpendicular mode. I don't know those command. One thing helpfull on the inner working of the floppy drive was the source code for the floppy driver IBM1FLPY.ADD. Third, Fix the problem with IRETD, switching privilaged rings (call gate), and one of the biggest show stopper, EXCEPTION 0Dh, for this I use ExceptionCHK, ExceptionSS and ExceptionCS global variables. These varibles are use to restore the previous values of SS and CS registers after an exception 0Dh occured. Tested on a Pentium II 400MHz CPU, under Windows NT 4.0. If you have any question on getting OS/2 to run under BOCHS, I'll be happy to answer your questions. You can write to me at . Regards, Diego Henriquez

I tried to install the 286 versions of OS/2 under Bochs and Virtual PC. No luck. I managed to successfully install OS/2 v2.1 under Virtual PC, and I'm about to try Warp 3.
