[Freedos-devel] I want my 10K

[<je...@sh...>]

Hi All, 

Let me show you a MEM print out from my Pentium Pro:

Modules using memory below 1 MB:

Largest executable program size       628K (642,688 bytes)
Largest free upper memory block        84K ( 86,144 bytes)
FreeDOS is resident in the high memory area.

As you can see, the only thing in low memory is part of SYSTEM using nearly 11K. 

The machine still has 94K free upper memory and 84K of that is still in a single large block.

Yes, I know why this is "the way it is" and you don’t need to explain it to me. 

But, it doesn’t need to be that way. That portion “could" be moved and it would free nearly all 
lower memory. Possibly through some cooperation between the Kernel and Jemm. Obviously,
the Interrupt Vectors, BDA, etc would need to remain. But, the rest could be in upper memory. 

But mostly, I think it would look really cool to have all Zeros in the Conventional Memory Column.
