My brother is trying to set up an OS/2 system (version 1.2) with both a
FAT and HPFS file system which he can use the dual boot option to boot
either DOS or OS/2. I remember a discussion many months ago about this,
but I didn't save the info.
If anyone has the procedure, could you email it to me, and I can forward
it? I can also post a summary if interest merits it.
Thanks!
Bill

What you have to do : 1) Partition your disk; one FAT and one HPFS partition. 2) Make your FAT the primary partition 3) Put DOS onto FAT partition (format /s!) 4) Run the installation program -> you'll be asked for the dual boot feature I think this is all there is to it. (The system I use only uses 1 FAT partition, but I think it will work for 2 as well). -- +------------------+-----------------------------------------------------+ | Hayo R.

Re the discussion on dual boot. The procedure outlined by Hayo Baan included a step (1) Partition your disk into one FAT and one HPFS partition. He then recommends putting DOS on the FAT and OS/2 on the HPFS. I'm just here to say that OS/2 gets along just fine with FAT, although there are certain advantages to HPFS. The computer on my desk at work is partitioned into C and D, both FAT, both DOS and OS/2 on the C drive. I support 45 more stations identically configured, and they all work fine. What I have NOT done is try and put DOS on HPFS. Maybe later ;-) -- Phil Tracy tracy@casbah.acns.nwu.edu Northwestern University

My brother (and I for that matter) would like to test out these 'advantages' to the HPFS... Thanks for the replys!

Just as a personal suggestion - put DOS and OS/2 both on your FAT partition and then use your HPFS partition for all of your OS/2 software other than the base system (such as compilers, development toolkits, source, etc..). I've installed quite a few OS/2 systems, and I always create at least one FAT partition for DOS-OS/2, and then worry about HPFS. The reason is that if something goes wrong (such as accidentally fouling up your CONFIG.SYS), you'll be able to boot a DOS diskette and make any necessary fixes to even the OS/2 files on C:. If you install OS/2 on the HPFS partition, you'll need to boot the OS/2 installation diskette, ESC back out to the prompt and then play with the disk. Boot time for a DOS diskette vs. the OS/2 installation diskette is significantly different. Plus, if you keep DOS and OS/2 on separate partitions, you'll need to be able to switch which partition is marked as active to be able to boot each system right from the hard disk. I personally love HPFS, and use it as the primary partition for all of my normal operations. I find that keeping all source, compilers and toolkits on an HPFS drive has really sped things up, or at least it feels that way. I do turn on lazy writing as well, which others may or may not want to do. Oh, and since it isn't in my signature - I may work for IBM, but these comments are strictly my personal opinion based on my own experience with installing and using OS/2 systems. -- David -- /-----------------------------------------------------------------------\ \ David Bolen / | Laboratory Automation, IBM Thomas J.

Re: dual boot... Make sure that DOS is on a FAT partition! As far as I know, (or as far as my own experience goes), when you boot under DOS only, you cannot read the HPFS partition. Thus, if DOS is on HPFS, I don't think she'll boot. Please correct me if I'm wrong, OS/2 world. Now, if you enter DOS through the compatiblity box, you can read the partition, which makes life kinda wierd. You see, I have four partitions: (1) FAT (2) FAT (3) HPFS (4) FAT (this is where my DOS apps are) What I ran into was that if I wanted to execute any DOS app from the compat. box I would 'see' then 3'rd partition, but under a DOS boot, I wouldn't see it. This plays hell with maintaining PATH, LIB, and INCLUDE environment variables. P.S. - I ended up making partition (4) HPFS, and (3) FAT. Soooo, to be safe I'm making it rule to put DOS apps before the HPFS partition I'm not sure if there's a better way...I'm sure there is.

I just got some dual boot software from someone here on
campus. It supports dual OS/2 and DOS booting including HPFS
partitions, but unlike anything else I have seen you don't need
to do any mucking around hacking boot sectors or other files.
You just run the menu driven installation program (very slick),
tell what systems you want on your boot time menu (oh yea, it
also supports any other OS like unix and different versions of
DOS and different config.sys and autoexec.bat) and then reboot.
Every time you boot you get a menu and you then pick the OS
configuration that you want. The software is beta, but I have
not found any problems with it. If you want more info E-mail me
and I will pass the request on.

DOS only recognizes partitions up to the first non-DOS partition. Also, DOS will not boot from an HPFS partition because DOS only understands the FAT file system scheme. In your first scenario, your 4th partition (FAT where the 3rd was HPFS) would be invisible to your system when booted from DOS. Too bad DOS didn't have a provision for an installable file system a la OS/2...
