[coLinux-users] Is it possible to use the 1GB of inaccessible memory?

[Louis <net...@ya...>]

Hi,

 I have a 32-bit Windows system with "4 GB" of RAM, of which of course only 3GB is accessible, so I was wondering, would it be possible for coLinux to use that inaccessible 1 GB of RAM? Probably not, if it wants to stay in good terms with the Windows kernel huh?

Yours,

Louis

I can say: No, it isn't possible. Why? The adress violation begins at the
BIOS and the CPU directly. Windows can only use what the CPU and BIOS make
available. And coLinux can't have more rights then the windows kernel ...

Actually I think you'll find that for the most part this is actually a
Windows limitation, see:
http://support.microsoft.com/kb/283037

Windows the operating system will limit the amount of memory that it
can address even if the system can support more underneath. So whilst
it might be an issue with the hardware, these days what is more than
likely the case is that its an issue with Windows. Of course, it
doesn't help that both Windows and the x86 instruction set are almost
the worst performing products in the market (e.g. compared to say
Linux and PPC respectively) so you're really in a doomed position to
begin with anyway.

BTW: When will there be a x64 version of coLinux? Anything in the pipeline
or the brains of the developers?

my top RFE
 1. multi core
 2. x64
 3. share filesystem cache with host os, and activly return memory to host os
i'm sure the user base is ready. ddr2 4G no more than 200RMB
(RMB==CNY, 25~28 USD). 2/3/4 core is popular

I wrote a todo list and some notes about problems:
http://colinux.wikia.com/wiki/Dashboard_for_developing_a_64_bit_coLinux

Additinallny developer needs to have 64 bit Windows. I don't have it.
