On my system (a 386 equipped with an AMI BIOS) the setup-program (ROM-resident) asks you whether you want the BIOS to use a stack area somewhere in low memory or you want it to reduce your base memory size by 1 K. I am not sure what this area is being used for - I guess it is used to store the user configurable HD drive information, but I am not sure. I do not believe you have a bug - what you could do is use Quaid Analyzer or a similar debugger to look into that top area of RAM (You might have to patch it back to 640k by changing 0:413 hex [dw]). By looking at the data stored there, you should be able to find out what is going on there. If that doesn't help, you could still use the Quaid Analyzer function "Go until memory location is modified" to trace the system starting at the boot so you can see at which point data is written to the hidden area. Not to forget: Quaid Analyzer itself also uses such a technique to hide itself from debugged programs if it is used in 'boot' mode.
