I have a Lenovo W700 that has 4Gb RAM. Originally it had SP 32 bit OS loaded on it but it didn't recognize all 4GB of RAM. So we decided to load 64-bit XP OS. After the installation I am having tons of problems with drivers. Right now in the device manager I have the following devices that have yellow question mark:
Base system device (Bus 21 device 0 function 4) = Ricoh RL5C592 Memory Stick Bus Host Adapter
Base system device (Bus 21, Device 0, Function 3) = Ricoh RL5C843 SD/MMC Host Controller
Base system device (Bus 21, Device 0, Function 5) = Ricoh RL5C852 xD-Picture Card Controller
PCI communication Controller (Bus 0, Device 3, Function 0) =Intel GL40/GM45/GM47/GS45/PM45 Chipset - Host Embedded Controller Interface 1 (HECI1) [B-3]
Unknown Device ( Intel(R) ICH9M-E LPC Interface Controller - 2917)
I ran Everest and found the exact devices matching it's location. I installed the PM45 chipset couple of times and I still get the questions marks.
Please let me know if you need additional information. thanks
