I have bought a IBM Thinkpad 560Z laptop with no operating system or internal drives. I want to load XP onto it. I have bought an IBM external CD ROM drive - USB 2.0 with optional split PS2 connectors. I have tried connecting it from the cd drives USB to the PS2 on the laptop, it lights up and I can put the bootable XP CD in the drive. However the same startup screen always comes up on the laptop. It is a picture of a floppy disk, with all the F keys along the bottom, the picture of F1 pressed down, and pressing between F1 and F8 just stays in a black screen, and gives "I9990302 I9990302 I9990305" if that means anything. You can't go any further. Is this because there is no driver for the drive? The USB driver is on a floppy disk, but does it need this going from USB on the drive to the laptops PS2? Do I need to get an external floppy drive and install it/another driver, to then install XP? What's the easest way to get XP on this machine?
