Setup OS/2 and Windows NT on one computer
aba...@ibm.net
I have OS/2 Warp 3.0 installed on my multipartition harddrive, and would
like to buy a second hard drive and install NT (3.51 or 4.0) on it.
Can I do this, and what will it take?
I'm asking because last time I tried to install NT 3.51
on my computer with Warp already there, my bootmanager failed to work
(I followed MS instructions for OS/2 users) and I could no longer use OS/2.
Two months later, my hard drive crashed and I had to get it replaced.
My current system is:
1.2 gig IDE hard drive
FAT primary partition with DOS 6.2
HPFS logical partion with OS/2 3.0
FAT logical partition non-boot
BOOTmanager partition
IDE CD player
16 meg ram
AMD 5k86-p75 CPU
and I want to install NT on a second hard drive partition 1.
Thanks

Yes, you can do it. A little effort is all it takes.

There's a nasty bug in the NT 3.51 Disk Administrator that corrupts partition
tables. Read Q135308 on the MS knowledge base if you want to know more. Get
and apply Service Pack 2 or higher (5 is latest) before invoking the Disk
Administrator.

NT absolutely requires to install a few hundred Kb of itself into a C: drive
on the first physical disk. In your case it'll share quite happily with DOS
6.2 and will present the NT boot loader menu when you select that partition
from Boot Manager.
What I do when installing NT is use OS/2's FDISK to set the primary DOS
partition to Startable myself before beginning the install. This stops NT from
seeing Boot Manager and it just offers to install itself into the primary
partition. You can change the location by simply highlighting a different
partition... but it still needs to place NTLDR and NTDETECT in the C: drive.
Once the install is complete, I apply the service pack and then (belt and
braces) use OS/2's FDISK to reactivate the BootManager partition.

This sounds like a good method. But will I need the service pack for NT 4.0?

I don't know. I've seen a couple of reports of NT 4.0 doing the partition
table thing *again* (it seems to be endemic with a non-service-packed copy of
NT, 3.5, and 3.51 both did it, now it seems 4.0 might too).

I have NT4.0/win95, Unixware and Os2 warp in the same 800MB drive.
They coexist well.
The only problem is I have to give OS2 boot manager a partition in the
first drive. Otherwise I can install something loke SCO openserver.
You better install NT or Win95 first, than install Os2.
If your OS2 bootmanager fails, use two OS2 install disk to install bootmanager
again. OS2 boot manager will only fail sometimes if you install some OS
after. I also have following sucessful installation order also.
1) Dos then WIn95 in partition 1(400Mb).
2)OS2 bootmanager in partition 3(1MB),
and then Os2 warp server in Partion 2(250M HPFS).
3)NT4.0 in partion 1(Trick here is to make partion 4 to be FAT when you install
NT from dos or Win95).
4)Install Unixware in Partition 4(150Mb vxfs).
In your case, just add your drive and choose second drive when you install NT.

Do a "Set active partition" on the Boot Manager.
If for some reason that doesn't work, boot from the Warp installation
diskettes and play the same game. (Make the Boot Manager partition
"startable".) (The only reason for using the DOS diskette is that it is a
bit faster.)
If all else fails, boot from the Warp installation diskettes again, delete
the boot manager partition and re-create it.
I've tried each of these methods. They all work.

What if you at some time in the future want to repartition the first drive (as
I do). NT will not let you do this because its boot files are on it. Is there any
way to run the NT boot manager off another partition or disable it completely and
let my OS2 boot manager do the work.
Thanx
