Accuracy

edit

The history given by this article is clearly inconsistent with what is claimed in EMM386. —Preceding unsigned comment added by 76.24.30.112 (talk) 20:59, 30 May 2009 (UTC)Reply

Memmaker

edit

Maybe we should mention something about 'memmaker' that shipped with DOS as we take the time to mention QEMM?

Addresses

edit

All of the addresses in the article seem to be using a 'segment address' which is only half of a 'real-mode address', making the addresses incorrect. It is probably a better idea to just use linear addresses in the article. For example, if I'm not mistaken, the monochrome video memory area is located at $B000:0000 to $B000:7FFF (or somewhere around there) which is actually a linear range of $B0000 to $B7FFF for a total of 32 KB of RAM (instead of the listed B000 to B7FF which is just 2 KB). The address $B000 falls in the Free RAM area of a PC, well below the Upper Memory Area. There are many ways to correctly represent the same segmented address, but all of the UMA addresses should fall between the linear addresses of $A0000 to $FFFFF (or $A000:0000 to $F000:FFFF for just one alternate representation). This range can be correctly converted from hex to a decimal range of 384 KB. 68.166.93.131 19:03, 16 May 2007 (UTC)Reply

Less than 1MB RAM

edit

I think it should be mentioned how less than 1MB RAM would be divided between conventional and upper memory. Josh the Nerd 02:44, 18 June 2007 (UTC) JoshReply

Should MOSNUM continue to deprecate IEC prefixes?
