So here it is. I have a Vaio PCG-R505TL. No internal cd or floppy drive. In need of an XP reinstall. I know about the i386 copy method and formatting C: /s to get to Dos in my laptop but for some reason my computer still doesnt recognize an OS upon powerup. So a buddy of mine and I came up with this possible solution. I'm sharing it with you to get your opinions. As you may have guessed by the title we want to introduce a desktop Cd Drive to the laptop via laptop IDE cable in order to install XP. Heres the rundown. Use a male to male 44pin adapter to connect the laptop MB to Y-shape 44pin laptop ribbon. One part of the ribbon will attach to the laptop HD and the other will attach to a 40pin/44pin adapter which will connect to the desktop cd-rom via another male to male 44pin adapter. Power to the cd-drive and 40/44pin adapter will come from my desktop computer. Think it'll work??
