|What drivers are you talking about? You should probably start by listing the system specs.|
If you plan on running both 98 & XP in a dual boot configuration, you should install 98 1st. And if you want 98 to be able to see files on the XP partition, both partitions will need to be formatted as FAT32. You're not gonna be able to install 98 with 4GB RAM though. You'll have to lower the RAM amount to 512MB or less, do the install, then edit the vcache settings in the system.ini file.
You'd probably be better off installing XP & running 98 as a virtual machine.
