- The following is an advanced look at an article which may appear in my column
- in the October issue of Windows. Naturally, we still want you to buy the
- magazine :-), but it seemed kind of cruel to force you to choose between
- waiting for this to appear in print and going thru everything I had to to

- Installing NT with OS/2 Boot Manager
- by Douglas A. Hamilton
-
- NT can indeed be installed on the same system with DOS, OS/2 1.3 and OS/2 2.0
- using OS/2's Boot Manager to choose what system starts up. If you'd like to
- do that also, read on. I can save you about 30 hours of groping in the dark.
-
- At the same time, let me also admit that I'm not specifying the "only" way to
- make things work, merely the only way I know about. If things go wrong in the
- install, it's easy to find yourself staring at a message telling you something
- like "DosPathToArcPath reported the following error...", but not so easy to
- figure out what to do next. Lots of things seem to interact and it wouldn't
- surprise me if there might be lots of "one-off" variations on the rules I'm
- about to give that could work also. The point is, I didn't try every
- combination -- with roughly an hour per attempt, it just _felt_ like I had.
-
- Point #1: Use the graphical install.
-
- There are two basic strategies for installing NT. One is the so-called
- graphical install and the second is a manual method involving copying the NT
- distribution tree onto your hard disk, editing the registry.ini file and then
- going thru what's referred to as the triple boot sequence where the system is
- rebooted three times as it builds all its security structures, etc.
-
- Don't use the manual method unless you positively cannot get the graphical
- install to work. Really. The manual method does not give you any way to set
- up printers, networks or any automatic way of trimming out drivers and other
- fluff you don't need. Since NT is already a big system with a big appetite
- for RAM, the last thing you need is a bunch of drivers that don't even go with

- your hardware being loaded into precious non-pageable memory!
-
- But also, don't use the manual method because the result seems to be
- unreliable. I understand and appreciate that the manual method is more or
- less what the developers at MS are using on their own machines, so clearly
- there must be a way to make it work. But on my machine, I consistently found
- that although the installation seemed to go okay and the system seemed to come
- up correctly, it was in fact broken. E.g., opening the command window and
- typing
-
- set | more
-
- would hang the window. Based on other experiments, it appeared that critical
- sections were broken -- as if I had gotten 1/2 a system built with one
- variation on the critical section structure and 1/2 built another way.
- Everything seemed to work except for critical sections. Unfortunately,
- critical sections are, well, sort of critical.
-
- Point #2. Put NT in the first physical partition.
-
- Actually, the release notes tell you this; they're not kidding. My first
- attempts were to do as little repartitioning as possible. And why not? The
- automatic install for NT that came with PDK2 didn't mind that the first two
- physical partitions on my system were the OS/2 Boot Manager and DOS.
-
- The install that comes with the July SDK is more fussy. Trust me: if you
- have Boot Manager at the start of the drive, or another (hidden) C: partition
- ahead of the one you're trying to install into, it will not work. You can
- waste a lot of time or you can just accept that fact and move on.
-
- Point #3. Don't try to install with the OS/2 Boot Manager on there at all.
-
- I found that if Boot Manager is on the drive, even at the end of the physical
- volume, install hangs with no warning during the scan it makes of your drives
- and you have to reach for the BRS.
-
- The trick to getting NT to work with Boot Manager is to put BM on there
- *after* you've already got a successful install done.
-
- Point #4. Don't try to install NT and OS/2 into the same partition.

- This was really strange I wasted a lot of time installing OS/2 1.3 into a C:
- partition, installing NT on top of it and then putting Boot Manager back onto
- the drive. I couldn't make it work. For some reason, you get the initial
- greeting from NT's Portable Bootloader, but it does not give its usual menu
- for selecting NT vs. whatever was previously on that partition. It just tries
- to load NT and then fails. Removing BM made it work again, but of course that
- defeated the purpose.
- If you want to use BM, you can put NT and DOS into the same primary partition
- (installing DOS, then NT) but not NT and OS/2 1.3.
-
- Point #5. Don't try formatting the partition with the NT install program.
-
- It does something wierd. My experience was that even when I specified a FAT
- format, the partition was not readable at all from OS/2 and even DOS 5 had
- problems with it, reporting a garbled partition size.
-
- Format the partition first with DOS or OS/2 if you want it readable by
- anything other than NT.
-
- Point #6. Don't try to put NT or even its pagefile onto anything but C:.
-
- Subtle point here: NT always, always, always has to be installed on C: but
- you do get options during the install (if you ask for the custom install) to
- place all the files that go with it (including the pagefile) on other drives.
- If you want to use Boot Manager, don't do that. What happens is that when you
- try putting BM on the drive after NT is already installed, all the drive
- letters (as seen by the NT Portable Bootloader) will get scrambled again and
- Bootloader will complain it can't find ntkrnl.
-
- When you're setting up that initial partition for NT, be sure to make it large
- enough (say 50 M or so) to hold all of NT + the pagefile. After you have
- *everything* (all the other operating systems and BM) installed, you can move
- the pagefile by using regedit. But getting started, everything must be on C:.
-
- Point #7. Don't try installing if you have more than one C: partition.
-
- The OS/2 2.0 FDISK program lets you create multiple primary C: partitions on

- the same drive, making just one visible at a time. Don't do that until after
- NT is already installed.
-
- Point #8. Don't try installing if you have any FAT or unformatted partitions
- that come _after_ any HPFS partitions.
-
- This had me in circles for hours. As long as I was repartitioning like crazy
- for NT anyway, I decided to do some other cleanup and get rid of several
- smaller partitions on which I'd had various beta versions of OS/2 2.0. All of
- them were at the end of the extended partition on my 3rd drive. So I
- collapsed them into one logical partition but left it unformatted.
-
- What happened was I'd go all the way thru the entire install process setting
- up printers, etc. -- I mean, we're talking about an hour to get right to the
- bitter end of the install -- and then it'd give me a "non-critical error"
- claiming that "External library procedure DosPathToArcPath reported the
- following error: Error reading object directory." You get a choice of
- whether to continue or simply admit right then and there that you're hosed.
- Trust me: you're hosed. What happens is that when you try to reboot NT,
- you'll get to the logon screen and it won't recognize your id or password.
- It's a secure system -- very secure.
-
- I don't know why, but it did occur to me that the problem might be because
- that partition was unformatted so I booted up the OS/2 install disk and tried
- formatting. But it's difficult to get OS/2 to do an HPFS format from the
- install disk, so I did a FAT format. That produced that same DosPathToArcPath
- error.
-
- What finally clued me in was booting DOS and using its FDISK to look at my
- partitions. Although DOS seemed to work okay with that partition arrangement,
- I noticed FDISK claiming I had two G: partitions, one an HPFS partition which
- it could not read and the second, that FAT partition. Going back to the OS/2
- install disk and simply deleting the partition (leaving it as free space)
- worked.
-
- Bottom line: if you have lots of partitions, be sure that any FAT or

- unformatted partitions come beforeny HPFS partitions. Otherwise the install
- will not work.
-
-
- Summary: Here's what to do.
-
- 1. Repartition as necessary to create a 50M+ primary C: partition for NT (or
- DOS + NT) at the very start of your boot drive.
-
- 2. Be sure Boot Manager is nowhere on your system, that there are no other
- primary partitions on that boot drive and that there are no FAT or unformatted
- partitions that come after any HPFS partitions anywhere on your system. We're
- talking plain vanilla here. Very important.
-
- 3. Format the C: partition with DOS 5 and then install DOS.
-
- 4. Install NT using the graphical install, putting *everything* on C:.
-
- 5. Boot the OS/2 2.0 install disk and ESC to get to the prompt, from which you
- can use FDISK to create partitions for OS/2 1.3, 2.0 and Boot Manager.
-
- 6. Install 1.3 and 2.0 in the usual manner.
-
- What you'll get:
-
- When you're all done, you'll have a system that'll have Boot Manager come up
- with a menu for choosing NT, 1.3 or 2.0. If you choose NT, you'll then get
- the NT Portable Bootloader, giving you a choice between DOS and NT. (Actually
- the choice will be between NT and the "previous" OS; you can fix the message
- by editing the boot.ini file.)
-
- QED. :-)
