I have met a real problem with my 386 . It's not an IBM, it's clone. However.. It has 1M base memory at morherboard (in SIMMs). The system finds only 640 Kb. I have tried to change setups for move memory that is betveen 640 Kb and 1M to location which is after 1M. I haven't succeed. The dealer who sold that computer for me said that it is impossible to use memory (betveen 640 K 1M) as an extendet or expandet memory. I doubt that he is right. If anyone knows something about that I would be gratefull if you send me a mail and give some information :-) th82787@tut.fi -- Tomi Heinonen th82787@tut.fi Tampere University of Technology -------------------------------------------------------------------- Atomikatu 6 A 19, 33720 TAMPERE, Finland (tel. -31 185 757)

Your question belongs in comp.sys.ibm.pc. Flame off: Almost every 386 board I've seen is capable of mapping the 384K between 640K and 1MB above the 1MB mark. The AMI 386 board which I've seen in a lot of clones only allows you to map 256K of the 384k. What type of motherboard is it? j |%|John Lawitzke, Dale Computer Corp., R&D |%|UUCP: uunet!frith!dale1!jhl Work |%| uunet!frith!ipecac!jhl Home Inquiring minds just wondering. |%|Internet: jhl@frith.egr.msu.edu

I have seen some cheap 286 clones which, when you have a Meg of ram installed, will allow you to have 512k base + 512k extended or 640k base + 0 extended. Thus, if you use the second configuration, you waste 384k of perfectly good memory, and there is no way you can get at it. It may be that the 386 board in question has the same stupid problem. Unfortunatly, I don't remember what brand or bios that machine was.

It may be that the 386 board The Packard-Bell PB286 is one of these. Shame on P-B. You either waste 384k of memory, or limit yourself to 512k of base, and lock yourself out of many nice programs.

However with a 386 clone using this configuration you can get one of
the extended memory managers which will re-map the 384K wasted RAM
into useable ram. I've also seen a number of memory managers for the
286 that will do the same if you are using one of the later Phoenix
BIOS's.
