#1 create the installation media (I used OS/2 Warp 4.52.086)
N.B. Do not use OS/2 Warp 4.0 as it won't be compatible on the T43 platform out of the box and will be too much of a headache. IBM never supported Warp 4.0 on the T43 anyways.
#2 format the drive, I would advise to formatting it completely with something like MHDD or Nuke 'n Boot because OS/2 does not like seeing other filesystems present and/or they can just cause problems
N.B. I am not sure the maximum size that it can address, I've been using 90 GB drives
N.B. Assuming there is a disk size limit, you can edit the .ISO and the 'virtual diskette' to incorporate Daniela Engert's replacement storage and ATAPI driver, but I've had no luck with getting it to work and it's not necessary for standard SATA drives on a T43.
#3 use the first BOOT CD-ROM and boot into it.
#4 The installation will (most likely) require to create an LVM partition and restart
#5 After the installation loads further, it will ask you to insert the client OS CD-ROM (disc #2), insert it and press enter
#6 continue through the prompts via enter, it will bring you to the LVM manager
#7 press ENTER with the CD-ROM partition highlighted (which will be the only thing in the list), you'll then have an option to create a new partition
#8 create a new partition as bootable
N.B. If you're using HPFS the maximum size is 64 GB, keep in mind the ancient CHKDSK can only do 16 GB. I would just do 16 GB HPFS and then JFS further partitions later.
N.B. If you choose FAT you'll be limited as to what you can install due to lack of long filename support; for instance you won't be able to install the latest WarpZilla package without HPFS/JFS which is a huge drawback.
#9 Change the drive letter to C:
#10 Select the C: volume and change it to INSTALLABLE from the list
N.B. OS/2 can only be installed to C:, any other drive letter it will simply ignore, so your installation volume MUST be C:.
#11 Create another partition if you wish, exist the logical volume manager (it will need to restart)
#12 rinse and repeat with inserting the boot disc and then the client OS disc
#13 you'll finally get to the setup screen, for video you MUST choose *Super VGA* (it's further DOWN in the list), DO NOT choose the default video selection that the installer thinks it wants. Else you'll get a trap error once the installer restarts.
#14 choose all of the options you want, you'll have to specify a password for your account etc.
#15 the installation should restart twice (it may ask to install an optional video utility, you can ignore it) and then you'll be greeted with your brand new IBM (R) OS/2 (TM) Warp (TM) desktop.
====How to install OS/2 Warp DRIVERS on a T43/T43p====
T43/p OS/2 Warp Driver Package Download: http://ibmfiles.com/ibmfiles/t43/T43_OS2_DRIVERS.zip
#1 OS/2 TrackPoint driver
Run SMOUSE.EXE and follow the onscreen instructions. It will require a reboot and you will have to manually set the speed to 'lightest touch' and configure the middle button to scrolling. Despite the driver being older, OS/2 features multi-window scrolling (so your cursor simply needs to be over the window to scroll whichever window, and it also does horizontal scrolling). These features would only show up in the very recent drivers for Windows.
N.B. You will most likely have to disable the 'touchpad' portion of the UltraNav since SMOUSE is designed exclusively to work with the TrackPoint. If you don't the touchpad takes precedence over the TrackPoint.
#2 OS/2 SoundMax sound driver
Run INSTALL.CMD and follow the onscreen instructions. It will require a reboot.
#3 OS/2 SciTech SNAP video driver
Run snap-os2-3.1.8 and follow the onscreen instructions. Reboot. Configure the resolution to 1600x1200 @ 16M. Reboot. It should now be working correctly. You will have to run the REGISTER utility and enter in the following to unlock the product so it doesn't expire:
Name: Free OS/2 Code
Code: 9F98-2AB9-9195-CC
[this was a free code that SciTech released after OS/2 became a dead end]
N.B. Don't use the IBM-supplied ATI driver since it is less featureful and potentially more problematic to get working as it's in an unusual distribution package unlike the standard SciTech one.
#4 OS/2 Broadcom ethernet driver
Follow Broadcom's official instructions to add the driver files in MPTS Network Adapters and Protocol Services. Remove the following from OS/2's startup folder: Network Messaging. You will need to manually configure OS/2 to run TCP/IP on DHCP on eth0: TCP/IP Configuration found under system setup.

Below this point is outdated information as I attempted to figure out how to get it installed. There are a handful of errors and incorrect statements (natural byproduct of the troubleshooting process) so take it all with a grain of salt. I'm leaving the errors and troubleshooting steps just for general documentation and in case it may be useful to anyone.

I really want to get OS/2 Warp 4.52 going on one or both of my T43s. XP is an awful OS, Windows 7 can be pushed on a T43 but it's not optimal... so why not have something 'different' (plus Windows 10 is not my preference). IBM did support OS/2, at least marginally on the T43 as per the T43 announcement document (since 98 is listed as well it can be taken on an as-is basis):
The problem I run into (so far) is thus: the Warp 4.52 installer will start, if there are already partitions on the disk it'll claim it has to reconfigure LVM / on one T43 (the one with a SATA mod), it'll do it endlessly, on the IDE one it'll get past it on a reboot.Software requirements: The following operating systems
support the ThinkPad T43 computer:
• OS/2 Warp Convenience Package 2 V4.52 Refresh MCP2 Refresh: XR_4503 with FixPak XR_C004, or later, and XR_D003, or later
• OS/2 Warp Convenience Package 1 V4.51 MCP1: XR_4501 with FixPak XR_C004, or later, and XR_D003, or later
• OS/2 Warp Convenience Package 2 V4.52 MCP2: XR_4502 with FixPak XR_C004, or later, and XR_D003, or later
• Windows 98 Second Edition with USB 1.1 support
• Windows 2000 Professional (no service pack, SP1, SP2, SP3, SP4) with USB 2.0 support
• Windows XP Professional (no service pack, SP1, SP1a, SP2) with USB 2.0 support
• Windows XP Home (no service pack, SP1, SP1a, SP2) with USB 2.0 support
• Windows NT 4 (SP6a) with limited USB 1.1 support
For information about support for these operating systems, visit http://www.pc.ibm.com/support
Note: Previous versions of these operating systems are not supported.
But the problem with both of them is that I can't install anything because it can't find the hard disks. I tried forcing the IDE T43 and just ended up with this:
Both hard disks don't exceed 100 GB. Does OS/2 require some sort of device driver, or a fix for drives past a certain size in GB?d:\os2/image\disk_2\format.com format error
