Acer Aspire 5520G - MXM Structure not found or invalid
#1
Hello everyone, and sorry for my poor English  Blush

I have Acer Aspire 5520G with latest official BIOS updated, but there is few issues.
First of all, my laptop see only 2 GB of RAM memory, I put in 2 modules by 2 GB RAM but BIOS see only 2GB!?
Second, my original NVidia graphic card is dead, I brought new MMX VGA card NVidia 9600M GT but when I start up computer there is 30 second message "MXM Structure not found or invalid".
I search internet about this issue and how I figured I need some modded BIOS or what?!
I flashed BIOS with flash from this thread ( https://www.bios-mods.com/forum/Thread-B...-7220-5520 ), and it was unlock my secret BIOS but that error about MXM Structure is still there.
May You help me about this, what can I do?
Thanks.
