Drive not ready.  Insert boot disk into drive A:
	
	
		I am currently trying to upgrade from windows 98 to windows xp.  I have upgraded the RAM to 256.  When I reboot I get "Drive not ready..  Insert Boot Disk into Drive A:".  I have gone into the BIOS and have changed the boot sequence to boot first from the hard drive then the cd rom.  It still doesn't work..  I changed it to boot first from CD rom.  It won't boot from CD rom.  Is there some kind of 3 & 1/2 inch floppy that I can boot from?  Where can I download this program?
