Welcome Visitor! Please take a few seconds and 
booting off it is another task, you'll have to first goto bios setup and select boot order making the 4.3 the primary boot drive. assuming the drive is still bootable, running windows 98 on modern hardware can be tricky, more than likely it will boot up and propt you for drivers, and once done pressing cancel because non are avalible, you'll be stuck in a safe mode like enviroment limited to 16colors, no sound, no internet, no other disk drives, except floppy, the cd drive will be read only. best option is to boot the xp drive with the 4.3gig set as master on its own cable by its self and copy the data of the win98 drive to your XP drive.
