OS/2 Multi-Boot on T42p

<< < (2/13) > >>

Dave Yeo:
I'm not totally sure what LVM does with the MBR as well. Generally LVM stashes some data in the MBR/EBR about drive letters, newer OS/2 lets you assign any drive letter you want to a partition, whereas older (Warp 4 or earlier) just assigned drive letters under the same rules as DOS. It also allows JFS volumes to span partitions.
Yes, I think that installing Bootman first, then BootManager in a small primary. OS/2 can be installed anywhere on the size of HD you likely have with the T42 and will install to an extended partition fine.
I don't know anything about Bootman and whether it respects reserved space in the MBR so guess you will have to test.

Wow.  Thanks.  I tested it out in a virtual machine (install takes a while with physical CD).  I used BeOS to make a BeOS partition, OS/2 Boot manager partition (drive setup had this option), and a HPFS/NTFS partition.  This does not format it.  I actually couldn't format as HPFS or OS/2 Boot manager.

Then I installed BeOS, and it's boot manager.

Then I installed OS/2.  I setup the one partition as C.  I couldn't set up one as "startable" and one as "installable".  I would like to know that process even though I may not need it now.

At this point OS/2 was booting, and seemed to have messed up the BeOS bootman in the MBR.  However after reinstalling BeOS, and it's bootman, it was able to boot OS/2.  It didn't seem like I needed the separate OS/2 boot partition.  I can tell better about the process for those who may need it after I install on the Thinkpad.

Dave Yeo:
Good, I'm somewhat surprised that OS/2 was happy with using BeOS to partition, OS/2 is picky and it is usually recommended to use OS/2 to do all the partitioning.
I've never actually installed OS/2 4.5.2, with OS/2 3 or 4 you use fdisk and can set the partitions startable or installable. I'd assume it would be similar but using LVM. eCs and ArcaOS have updated disk managers and installers. Also bootable JFS so no need for HPFS.

_AP:
I'm running into some issues with Windows XP and OS/2.  They aren't playing nice.  Neither one seems to want to install to anything other than C:

How can I install OS/2 Warp 4.52 to D:  I can set D: to startable, but not installable I'm LVM.

I have
16GB Windows XP
8GB OS/2
40GB BeOS
    Logical
32GB Haiku
20GB Slackware

If I install OS/2 first, on C:, Windows XP will only install to C:, and I can't change the drive letter during installation.  So I would like to install OS/2 to D:, if I can't install XP to D:.

Dave Yeo:
Can you hide the XP volume from OS/2? Otherwise I think you will have to install boot manager before you can make D: installable
