Mac OS X 10.5.5 using external USB Drive


1 post in this topic

Recommended Posts

There are a lot of successful stories on Dell Inspiron 530 but there is a little bit difference for my topic. I am using an external USB Drive for the installation and boot the Mac OS X using the F12 of BIOS. I believe it is the less intrusive way because no change is made to the built-in hard drive. If you unplug the USB Drive or keep it turned off, it is the original Dell Inspiron 530 with Windows XP Home.


You could search for the required downloads from InsanelyMac Forum or Google.


Here is my story...



Dell Inspiron 530 Configuration


• Intel Core 2 Quad Q6600

• 4GB 667 MHz DDR2 SDRAM

• Internal 320GB SATA Hard Drive

• USB 320GB IDE Hard Drive

• Integrated Intel 7.1 channel High Definition Audio

• Integrated 10/100 Ethernet LAN on system board
