IBM AIX

[ArtiomWin]

I have problems with install of AIX 1.3: when I put Install floppy, it gives 911-455 KERNEL TRAP. Config is included: AIX PS2.zip

I'd need the NVR folder as well.

[ArtiomWin]

OK, here you are. nvr.zip

This looks like a bug with the IBM MCA ESDI controller.

I've tried to install AIX again on recent build, this time on SCSI. Result is "Error in obtating information on hard disk drives available" (this issue was on earlier builds also). NVR and configs included. nvr+cfg.zip

I think AIX doesn't support the current emulated SCSI cards, iirc it only supports the IBM SCSI card, which is not emulated and also poorly documented.

[ArtiomWin]

Well, documentation for IBM SCSI adapters is harder to find, but at least that's not 8514 adapter. Here's technical reference for IBM PS/2 SCSI Adapter with Cache: http://www.mcamafia.de/pdf/ibm_scsiwc_trm.pdf

Correct.

The IBM PS/2 SCSI Adapter is going to be implemented in v2.10 based ont he technical reference manual.

Well, I'm glad I made a contribution, but I'm going to return to question of ESDI: is it going to be fixed?

[OBattler]

The IBM ESDI controller is going to be fixed at some point in the future.

I'm still getting the kernel trap bug with the IBM MCA SCSI controller selected...

Attempted to reproduce this bug but could not find a version of IBM AIX 1.3 that was bootable, with the one I found on WinWorld having "Non-system disk or disk error" for the ESDI boot disks and install disk.

Thank you for the link! These disks are bootable this time. I think I'm getting the same issue with ESDI but I'm not sure to be honest, because it gets partway into the boot process and then immediately reboots before I can read what the error onscreen is. It at least gets to this point first:

I had to use screen recorder, but here's that screen:

When using IDE configurations with the ISA support from PTF0024 which you have in your disk set there, many boards have a similar kernel trap at roughly the same point in the initial boot as this one for the ESDI PS/2 systems, and some work fine (e.g. socket 2 SiS 461 PS/ValuePoint, socket 7 single voltage hp vectra vl 5 series 4, slot 1 asus p3b-f, slot 2 supermicro s2dge). Is there some kind of difference anyone can spot between these boards that might explain this, maybe not in 86box as such but some kind of firmware/initialization difference? Anyway, I wonder if this is related to the kernel trap on these ESDI configs.
