OS2 on IBM T42 found a drive greater than 8GB

#1 Post by matti157 » Sun Mar 16, 2025 7:40 pm

Trying to install OS2 4.52 using that image from Winworld

Code: Select all

IBM OS2 Warp 4.52 (14.089_W4) (CP 2 Refresh) (2002-04) (ISO)
I have a 128gb ssd on it, it runs well Win98 and XP

Now I deleted all partitions on the disk, but the setup gave me this error.

Code: Select all

YS732: IBMInt13.i13 found a drive greater than 8GB
OS2 is unable to operate your hard disk or d diskette drive
That system is stopped. Correct the preceding error and restart the system.
How to bypass the limit?

I have searched the Internet but cannot find the specific error. Am I the only one who has it? o.O

Try format just 1 partition at 7-8GB.
Install OS2, then format the rest for storage.

I didn't specify it, but the disk has a single 1024mb FAT partition

I solved by avoiding booting from CD and booting from these floppy disks https://archive.org/details/OS2Warp4.52UtilityDiskettes

Loaded the third floppy just insert the CD and give the command “CDBOOT” in the terminal that opened. Doing so starts the installer and the partition manager detects my 128GB SSD

unfortunately I'm stuck again :(

With the linked floppies I created a partition and did the first part of the setup. At one point the setup asks me to remove the floppy and reboot.

It boots from C: with the version of OS/2 on the CD, which is older than the floppies, so I get the same error as the 8GB

I'm not sure at what point in the process you're getting stuck on, but OS/2 4.52 _doesn't have_ an 8GB limit by default. I would probably suggest going over my checklist and scrutinize every point, including the red text:
viewtopic.php?f=10&t=120744

When I installed it the disk was 90 GB and it never falsely reported an 8 GB threshold, unless the OS simply does not want to see a maximum capacity of 128, I am not sure. I doubt 128 is the limit though as this was already competing with XP. If you didn't completely zero the disk, those Windows partitions could still be causing a problem too.
