Strange memory maps!
Posted: Sun Aug 10, 2008 1:52 am
Hi,
Ok, here's the strangest memory map I've seen:
That's 2 ACPI reclaimable areas, 2 ACPI NVS (Non-Volatile Storage) areas, and 8 separate RAM areas! 
This is from a relatively modern Intel machine - an Intel DG33FB/DG33BU motherboard with an Intel BIOS. I used "BIOS Int 0x15, eax = 0xE820" to get the memory map, and thought it might be interesting for others to see how messed up it can get.
I was also wondering if anyone has a computer with an even stranger memory map - post yours if it looks unusual!
Cheers,
Brendan
