- Yes! It is possible to use both--I have done so for the past four months!
- The trick was to make the OS/2 boot sector appear to be a DOS boot sector.
- I am assuming that the problem is discovered during the wonderful install
- process, in which case, I will have to think of another way to help--I had
- some extra tools at the time which helped a lot. At any rate, here is what
- I had:
-
- A 312MB (or so) SCSI disk was made as one partition and formatted as FAT. I
- did this using a DOS (5.0) bootable floppy with FDISK and FORMAT on it. I
- then installed OS/2 2.0 using the generic process (keeping the FAT file
- system). I then installed NT using a non-standard technique (I can't
- remember what I did four months ago, because once it worked, I didn't have
- to repeat the process), and also using some special tools. Once I was done,
- I had OS/2 2.0 and Windows NT installed; the NT boot sector was in place;
- the OS/2 boot sector had been saved to a file called BOOTSECT.DOS (note that
- it is NOT BOOTSECT.OS2!); and everything appeared to be happy. I was able
- to selectively boot either NT or OS/2 using the NT select boot menu.
-
- If this doesn't help, perhaps a more creative way would work--let me know.
- If everything is installed, maybe changing the name of the BOOTSECT from
- .OS2 to .DOS (found in the root directory) might help. I am rather
- skeptical on this one, and make sure you are using FAT or HPFS in case
- something happens.
-
- Now, to completely get rid of that nasty NT boot sector, either use SYS if
- you want DOS, or use the SYSINSTX.COM (I think that is right) found on
- either disk 1 or disk 2 of the OS/2 install set--it is NOT in any OS/2
- directory by default. This is the program that OS/2 setup uses to make your
- harddisk OS/2 bootable in the first place.
-
- As a side, note that in this case I did not use the OS/2 boot manager, nor
- the OS/2 dual boot feature. Also, I do not use the funky path names seen in
- NT's BOOT.INI file. I always change them to a dos-standard path:
-
- i.e., from SCSI(1)RDISK(4)PARTITION(?) or whatever
- to C:\ or whatever
- (Make sure you still have a name in the quotes.)
-
- Last word of caution: this stuff can be a real pain, and for convenience
- (and sanity), I suggest using the FAT file system for now, and keeping a
- DOS-bootable floppy close by (with a text editor and some good utilities on
- it).
-
- Let me know how y'all fare--not responsible for systems that become hosed!
- Happy hacking!
