Sorry to bump a thead with only more questions instead of answers, but this looks exactly like issue I'm having, and I wondered if there'd been any progress.
I won't repeat my tedious memory problems in their entirety (it's all detailed in
this thread should anyone care), but the short story is, my BIOS appears not to have an option for memory remapping, and I suspect this is the reason for my 4.00 GB of RAM not being used to the full.
Also, despite previously describing my BIOS as being 'Award Software version 10Q', according to my computer's registry it's actually 'Award Modular BIOS v6.00PG', but there's no suffix like 'v3.17' or anything as mentioned as in the title of this thread.
So, what I really wanted to know is, would any of the different versions of BIOS linked to in this thread also work for me, or would I need a specific update for my motherboard (Gigabyte (Fujitsu-Siemens) GA-8I915PM Revision 2.0)?
And would anyone happen to know for certain whether a memory remapping option is actually even hidden away in my BIOS anyway?
