IBM PS/2 + EDSI Controller: Soft Lock during IBM OS/2 1.3 Install

[J03yPJASDF]

What happened?

While Attempting to install IBM OS/2 1.30.2 Extended, with new hard disks there's the ineveitable problem of needing the format the disks first, I natually choose for the main Hard Disk HPFS (High Performance File System, OS/2's predicessor to NTFS), but then this bug comes up.

And it stays there, formatting the Hard Disk, forever, and ever, and ever.

Steps to Reproduce
1#: Set up a PS/2 Model 55 SX, as you would any other machine. with the appropriate reference disk. (Be sure to add the ADFs for the MCA devices not on a fresh downloaded disk image.)

2#: After the BIOS Setup is down, insert the OS/2 1.30.2 Extended Install Disk and boot into the install.

3#: When it comes up, Select 'Specify your own Primary Partition', and type the size of the Hard Disk image as determined by the MiB under 'Hard Disks' in the Settings

4#: After a reboot, and following the install instructions, Select 'High Performance File System' for the File System.

Expected Behavior:
The Disk to finish formatting and the setup to continue.

Additional context

Same config as the previous 2 IBM PS/2 Bug Reports I made, also if I recall this bug has been in as far back as 86box 4.0

Test VM:
PS2_55SX_OS2.zip

Modified PS-2 55SX-65SX Refrence Disk.zip

This issue doesn't seem to occur on the PS/2 Model 65 SX.

EDIT: Ignore the previous line, this happens on the 65 SX too, I tested this myself.

[OBattler]

Well, if it does not lock up on the Model 65 SX, then this indicates a BIOS bug, since that's the only difference between the two machines as far as ESDI is concerned.

[J03yPJASDF]

Correction on my part (And I probably should've verified this for myself earlier.), this happens on the 65 SX too.

I'll test the Model 50 next to see if the issue happen there too.

[J03yPJASDF]

And with the Model 50 86box itself softlocks.

I tested with the Model 60, same problem as the 55 SX & 65 SX,but it has another unrelated problem with memory. (it keeps giving me a 164 error no matter what, with or without a memory expansion.)

So dose this boil the problem down to the EDSI controller or what?

[TC1995]

You need an updated adf for the 60.

[TC1995]

Does it happen on a 80 or 70?

[TC1995]

Also, I've tested 1.30.1 Extended Edition (German) 7.85, no issues with ESDI on 65sx with the HDD formatted as HPFS.
