But I should still see 4GB without any patch. Right?

Windows only see 1.92GB as “Installed Memory (RAM)” in Control Panel->System.

I am happy for the system to see up to 4GB only.

Hello Naveed,


For you to read: https://en.wikipedia.org/wiki/Physical_Address_Extension


Important: With PAE, IA-32 architecture is augmented with additional address lines used to select the additional memory, so physical address size increases from 32 bits to 36 bits. 


Then, after reading, this can/will help you: https://wj32.org/wp/2011/02/23/pae-patch-updated-for-windows-7-sp1/

Hi all,


I am booting a 32 bit Win 7 image (via Seabios).


Windows is detecting only 1.92GB (even though there is 8GB of memory available.

Being a 32 bit OS I would have expected it to see at least 4GB.


Coreboot logs shows:

Available memory below 4GB: 0x7ae00000 (1966M)

Available memory above 4GB: 6144M


What can cause the full 4GB to not be seen. Should I install only 4GB of memory instead of 4GB? I have ordered some to try in any case.
