A friend of mine has a package called 704K.ARC or some such which puports to give you 704K of DOS accessable RAM on a monochrome or CGA system by somehow making real memory appear at locations A000-AFFF which aren't needed unless you have a VGA/EGA. The documentation is *very* vague and doesn't explain to him or me just what sort of physical memory situation you must have (since I assume you must have more than 640K *physical* RAM in your machine). It doesn't really explain anything and to make a long storey short, we can't get the pgm working. I have seen programs similar to this in the SIMTEL archives, etc. but they all require you to have EMS 4.0. My friend has a 286 with 640K base mwmory and 384K extended (1 Meg total). Would anyone be familiar with this package and kindly explain how, and under what circumstances, it works. Would anyone have a similar package that could be used by friend send it along. Many thanks.

A recent PC Magazine mentioned a package called 386-To-The-Max or something like that, which allows you to load your TSRs in high memory. Does anybody know anything about this package? 704K.ARC won't do me any good since I have VGA... \tom haapanen "now, you didn't really expect tom@mims-iris.waterloo.edu my views to have anything to do watmims research group with my employer's, did you?" university of waterloo

If you have more than 640K physical memory available (presumably extended memory although some machines have 384K of "shadow memory") 386Max will use the hardware memory mapping features of the 386 to make that memory appear between 640K and 1MB. 386Max then provides a utility program with which you can load TSR's above 640K. I have this and it works well. 386Max also has an optional package for loading device drivers above 640K, but I don't have it and c an't comment on it. -- Howard Spindel - via FidoNet node 1:105/14 UUCP: ...!{uunet!oresoft, tektronix!reed}!busker!14.8!Howard.Spindel ARPA: Howard.Spindel@p8.f14.n105.z1.FIDONET.ORG

Is this a commercial package? shareware? public domain? Also, will this work with any TSR's and device drivers, or do they have to be written specifically for this (like himem.sys)? Sounds like a good package if it works with anything. --- Rick Stoen - Iowa State University Internet: stoen@atanasoff.cs.iastate.edu UUCP : {hplabs!hp-lsd, uunet!umix!sharkey}!atanasoff!stoen

After replacing the ROM BIOS on my PC-1 (64k motherboard PC), I put 704K in the PC (64K on motherboard, and 640K on an AST board), and set the switches to 704K. It worked just fine. That was just normal RAM, that responded to addresses A0000-AFFFF. Yes, a monochrome machine. You'll need real memory addressed at A0000-AFFFF, and a program to initialize it, and tell the system about it, in "smarter" clones that automatically determine memory size (up to 640K). I kept running into that old 704K barrier when running programs! :-) Steve Ligett steve.ligett@dartmouth.edu or (decvax harvard linus true)!dartvax!steve.ligett

Can someone tell me where I can get 704K.ARC and/or how it works. A friend of mine says he tried it and couldn't get it to work, possibly because of unclear documentation.
