ThinkCentre M93 Tiny
« on: July 17, 2017, 05:50:53 pm »
I've finally managed to boot up OS/2 on my ThinkCentre M93... Unfortunately the keyboard and mouse don't work, so I can't do much with it :(..

I have the latest USB drivers installed. Can anyone suggest what I might have overlooked?

The USB drivers depend on ACPI and the Kernel. The M93p tiny is working here under eCS and under ArcaOS. I have legacy USB on in BIOS. M92p tiny is working also with the same software.

Good to know you have it working... I checked USB setting in BIOS and legacy was enabled.. . Tried disabling and was unable the choose BOOT MANAGER options, which suggests that some OS/2 device driver is missing or incorrectly set.

Which Kernel and ACPI versions do you have?

Hi John

The Legacy USB setting in the BIOS Enables keyboard and mouse support prior to an operating system loading USB drivers for those devices. So if you Disable the setting and have a USB keyboard you will not be able to select any volume to start from Boot Manager but will be stuck with the default boot option.


Regards

Pete

Which Kernel and ACPI versions do you have?

For eCS, the kernel is SMP 14.106
For ArcaOS, the kernel is SMP 14.200

For both, ACPI is 3.23.05

The USB drivers are 11.16

I have:-

kernel 14.106

ACPI 3.23.1

USB 10.218

The USB drivers are the latest available  on Hobbes, dated 2017/06/18.

Are you sure that my keyboard/mouse not working is due to using different versions of these two drivers, ot could it be something else?

It might just be the ACPI driver try one at a time and reboot each time.

Strangely enough when I boot using QSINIT, the keyboard works, at least I can press ENTER when errors pop up during booting, but the OS/2 image I'm using doesn't have the correct display drivers so PMSHELL does not start.

Need to update the OS/2 image with PANORAMA....

Also need to find NIF for M93 Tiny... Not sure what NIC is used  though...

I'm going to lose access to my m93p tiny, but I tested UniAud32.Sys /A:1 and sound comes out. It's horrible, though, looping and distorted.
