Thread: IBM PS/2 Model 53 - Hangs when exiting WFW 3.11

  1. #1

    Question IBM PS/2 Model 53 - Hangs when exiting WFW 3.11

    Background on configuration: I am running an IBM PS/2 Model 53 (9553-0B7) . It has been upgraded to 16MB RAM with an added MicroChannel 3Com Etherlink/MC (3C523) ethernet adapter. Software and OS running DOS 6.22, Windows for Workgroups 3.11, Norton Desktop 3.0 for Windows, and Norton Utilities 8.0. Using Cirrus Logic GD5422 GD5424 Windows 3.1 Drivers v1.50. For networking, I am using Microsoft TCP/IP-32 version 3.11b. The system works perfectly, with one exception...

    Question: When I exit Windows and try to return to DOS prompt the system hangs. I feel like it might be a display driver issue or a hardware conflict of some sort. Does anyone have any troubleshooting suggestions or ideas on what might be causing this problem?

    You tried unloading drivers one by one until you find the one that causes things to hang? Could the TCP stack be going weird when Windows exits?

    Its my recollection that WFW3.11 was prone to this. Our IRMA cards (IBM co-ax terminal controllers) seemed to cause it to happen. Just fiddle with the drivers as Next says..

    I've determined it has something to do with the networking drivers. When I load WFW 3.11 without networking and then exit back to DOS all is well. So I'm wondering if I have an IRQ or other hardware conflict. The card is in slot 1 using IRQ 3. I have no other cards installed. Using onboard SVGA and mouse/keyboard ports. Wondering if I should try IRQ 9 or change the memory range in BIOS.

    I have that same issue with my Presario 425 and I have a GD5420 that uses the same drivers (mine might be slightly newer, 1.53? I'll check if it becomes relevant). Definitely didn't have the issue before but I wasn't sure when it cropped up. I'd say try using the default Windows video driver for plain VGA or SVGA and see if the hang still happens.

    It may well be that the GD542x driver and something with the networking are conflicting. My setup is similar to yours..

    MS-DOS 7.10
    WFW 3.11
    TCP/IP-32b, NetBEUI, IPX/SPX (may have removed IPX/SPX, can't recall at present)
    QEMM97 Memory Manager
    Hurricane 98 (memory tools for under Win3x, ones packaged with QEMM97 only deal with DOS and 9x)

    You could try throwing a different video card in there and seeing if it plays nicely with the rest of the setup as-is, assuming the board knows to disable the built-in one. I don't have that option on my machine as the monitor is wired into the motherboard via edge connector and you can't put a video card in (unless maybe I used an external monitor? Don't really care to try, anyway, as I use the two slots for other things).

    Hardware-wise it's a Presario 425 with a Pentium ODP 83Mhz CPU, 20MB RAM, SB16 Value (16-bit ISA), and a Kingston EtherRx full duplex 100mbit wired ethernet card (16-bit ISA).

    It's always possible that the hanging issue is unrelated to whatever causes mine, but its suspicious that we're running similar software with similar hardware and seeing similar problems, so Occam's razor..

    Hi Raven,

    Thanks so much for the detailed reply. The video drivers is an interesting suggestion. I believe the ones I acquired came from this site --> http://www.vogonsdrivers.com/getfile...83&menustate=0

    If you know where anything more current might be located, please let me know.

    But I am going to change to the default Windows VGA driver to see if that has any effect on the system hang.

    I'm presently using drivers that show up in the Windows Setup applet as "GD5422/CL-GD5424 v1.50e Windows drivers".

    If you're only using 1.50 with no revision number I can get you these, I just wish I knew which file it was from where that I ended up using. I think it was one of the ones on this page:

    http://ftp.mpoli.fi/pub/hardware/DISPLAY/CIRRUS/

    Careful if you touch those VBIOS updates, they instantly write over your VBIOS the second you run them, and there aren't extractor programs - they just go. I nearly murdered my GPU in this box, but thankfully they had the version of the VBIOS for it that it originally had here so I was able to restore it (it rendered really screwy in non-textmode, as the VBIOSes have hardcoded amounts of VRAM for some ungodly reason!).
