ThinkPad 600 PCMCIA Problems (Win 95)

#1 Post by nick99nack » Sun Oct 08, 2017 12:08 am

Hi all,

This is my first post here, though I've been lurking for a while, and I've been collecting ThinkPads for a few years now.

I'm trying to install Windows 95 on my 600, and for some reason I can't get the PC card slots to work. It says in the device manager, "Texas Instruments PCI-1250 Cardbus Controller" with the yellow exclamation points next to each listing. If I go to "update driver" and tell it to install the driver that's already there, it will install and the slots will work perfectly until I reboot the machine. Then the yellow marks come back and I have to do the process over again.

Device status is Code 29: "This device has been disabled in the hardware. In order to use this device, you must re-enable the hardware."

I don't know how it can be disabled in the hardware, when installing the drivers seems to activate it, at least temporarily.

Any help would be appreciated, I've been trying all day to figure this out.

Thanks in advance!

Have you installed the Configuration Utility? IIRC old models like the 600 need this program to enable/disable devices like the PCMCIA/Cardbus slots, serial/parallel/IR ports, etc.

I just installed the configuration utility and it acts like the drivers aren't installed. Then the same thing happens where if I install them, the utility shows them as enabled until I reboot the machine.

It seems like something should be initializing during Windows startup that isn't, and when I reinstall the drivers it forces it to start. I'm not a Windows 95 guru, so I'm wondering if there's something extra I have to set when I install the drivers to get them to "stick" (I learned NT4 and 98 originally).

It's been a long time since I messed with PCMCIA drivers, but as I recall the DOS drivers and programs, or "real mode" was different than the Win95 driver and programs. There are/were warnings in the IBM ThinkPad text documents about trying to use both or one vs. the other. It also had configuration info for .inf files for specific ThinkPad models. It was by no means a simple program install for Win95. Default memory address ranges and IRQ's were not the ones used.
I'm not at home so I can't look through my library for specifics, but the win95 setup text document should be available in the same place the ThinkPad drivers are.
Perhaps you're just one address range off in your settings.

In the olden days there were autoexec.bat and config.sys, which played a major role in startup procedures.
Adding that driver to config.sys would be my guess...

Well, I managed to finally get it going! I found a guide to installing Win95 here: http://ps-2.kev009.com/pcpartnerinfo/ctstips/ca9e.htm

It seems that installing the PC card slots before the rest of the drivers is what made it work. I'm guessing it has something to do with how Windows assigns resources to each device. I tried setting them manually but they would always revert back for some odd reason.

Now maybe I can finally have some fun with this machine :D

Thanks again!
