Memory Mapping

February 23, 2010 at 15:11:28
Specs: Windows 98 SE
I have a unique type of card, (Allen Bradley 1784-KTX), that wants me to set a 4K block of "Base Memory Address" for it. The card has an assigned address of D700:0000.
How do I do this? It has DOS 6.22. The Bios has the capability of setting asside the segment from 512 to 640, but I think that is wrong, its too low?
HELP!!!!

Yeah, leave the system memory at 640 in cmos/bios setup.

Running memmaker may be all you need to do. At the dos prompt type memmaker and enter. When it asks if you need expanded memory answer 'yes'. It'll reboot a couple times while it's configuring your memory.

I downnloaded that but didn't see anything in it about configuring config.sys or the emm386 line in config.sys. I think that's typically done with the utility software, which I'm not sure he has. There's some other downloads on that page:

which may help but I didn't see anything that mentioned dos setup.

If memmaker doesn't pick it up, the emm386 line would have to be manually edited, something like:

device=c:\dos\emm386.exe ram x=d700:0000-xxxx

where xxxx would be the upper address.

Also, EMS may not be needed so RAM coiuld be replaced by NOEMS.

Or Quarterdeck's QEMM might work better.

Yeah, I have the KTX manual, but it does not provide enough detail. It is the code lines examples in the last post that I need. I have a feeling that there is more than one way to skin a cat on this setup...
But will it fit my system in a "generic" way? I look forward to trying it. Thankyou.

I jsutnoticed that htere is no upper address to specify, but it does state that I need 4K of memory.
What is 4K above that?

4K above D700 would be D7FF. You can manually edit X=D700-D7FF to the emm386 line but I'm not sure whether it should be RAM or NOEMS.

Also you should probably try it with memmaker first and see if it picks up that hardware address on its own.
