Optical Bay Hard Drive caddy not recgonized, system hanging/not booting
Replaced the optical drive of my laptop (Dell Inspiron 1464) with a hard drive caddy to extend the storage capacity, but the BIOS seems could not recognize it.
After some digging and checking, I noticed that the SATA port in the laptop for the optical drive is only 1st gen (150MB/s), and it does not support the SATA II type (300MB/s). So I changed the mode of the dard drive into SATA mode with copper wire (jumper settings, to change the working mode), and it works perfect.

Network problem with VMware Fusion bridged autodetect mode
Vmware fusion 4.1.0 under OS X has a bug when using Bridged autodetect mode.
For example, suppose you have a cabled ethernet and also a WiFi connection. If you set the Guest OS to use ethernet as bridged with autodetect mode, it works fine at the beginning, but when you switch your Host internet connection from cable to WiFi, and switch back, the Host ethernet would not able to determine the status, let alone establish a connection.
The solution is easy, set the Guest OS to use ethernet as bridged but with a specific network adaptor and problem will fix immediately.
