Peter, have a look in the utility documentation for ConfigTool 1.3.0 as to what it says for:


Hmm... have not used ConfigTool recently myself. I think the last version I looked at was 1.2.2 which, for some reason that escapes me at that moment, did not impress.

Guess I ought to look at 1.3.0




BASEDDEV=OS2PCARD.DMD  PC-Card Device Manager
 <<=Attention=>> Must be in before $ICPMOS2.SYS.  If no $ICPMOS2.SYS
 installed it has to be the last line in the config.sys

DEVICE=C:\OS2\$ICPMOS2.SYS /G
 Power Management Driver for PCMCIA
 <<=Attention=>> Must be after all other listed drivers in the config.sys


Well, looks like there are "dependencies" that need to be sorted for the benefit of those people using either or both of the above drivers.

I may well go for the easier option of making sure the above drivers are
last in the config.sys file - in the order stated above - if they exist in the config.sys file being changed.


The interesting bit about the above drivers is that the config.sys line placement required suggests that those drivers do not obey the normal (? if there is such a thing) config.sys "loading order" - otherwise the positioning would not matter too much.



The issue surfaced from another direction in the recent research that is, I think now done, on the floppy diskette utility boot operations for the IBM Thinkpad line as well and the DOS-VDM video corruption on the IBM R51 Thinkpad here which is now working correctly for DOS-VDM video on windowed sessions. That courtesy of work just last released for the IBM GRADD changes and the recent changes in the SNAP 3.1.3 latest release. In updating the system from SNAP 3.1.1 which in test also saw the video smash on this R51, I had to revert to VGA video. Then I had to uninstall the earlier 3.1.1 and then install the 3.1.3 version.

The latest Scitech install procedure also reworked the bottom of the CONFIG.SYS file as is being discussed here. It chunked their lines under the required $ICPMOS2.SYS /G line. And that had to be cleared up to get the R51 running again .. by hand, from a command line boot and hand edit of the CONFIG.SYS file. Together with proper working of the Diamond 56K PCMCIA modem that is working just fine in the R51, as well as the Best 56K PCMCIA modem which is working fine in OS/2 in my R40 Thinkpad here.


I didn't create the issue for the absolute bottom line requirements for what you do in the OS/2 CONFIG.SYS file. IBM's own driver development crew either had a reason it has to be so, or .. didn't cure the reason it works out to be that way, in the release of the Card Buss and USB plus the OS2PCARD driver work.

And .. from actual experience here at what is required at least for some models of the Thinkpad line, pure IBM orchestrated, you absolutely have to pay attention to how you write to CONFIG.SYS.

Which .. incidentally, for some IBM products, and their installation coordination, requires that the CONFIG.SYS file still have a hard CR LF line end for that last line!


True, I may have a lot of stuff like Smart Suite for OS/2 and USB and card buss stuff and all running on OS/2. But it's not, as I see it, that my requirements are so special. It's a fact of life on how OS/2 handles the CONFIG.SYS file that IBM's operations mandate which control this. In my humble opinion .. from getting torched by this already. I'm just trying to contribute here, that's all.


Thanks very much for the above info - Not being a laptop user I would never have known.

Regards

Pete
