Meaning you don't have the drivers for it? Probably not a big deal. Just make a boot disk, boot to that and run fdisk to delete all partitions, create a new one or ones, then reboot again, and use the format command to format them, and you are ready to reinstall. Boot from your boot disk (must be Win 98 or better boot disk) it should get your CD going so you can run setup from the cdrom. Win 98 should detect all or most of the hardware, enough to get you up and running...I have found it to be surprisingly good at this with older computers I didn't have a driver disk for.
