windoes 98 verses 98 SE

I have windows 98, with a 266 MHz, AMD K6, processor, that is fine on the box
( new Mad Dog 4-in-1 Dominator ) but on the box it also calls for windows 98 SE, and I spoke to a member of their tech staff who said the drive and all it's software would work on my system.
Is their anyone out there who has or knows of similar situation or has used the Mad Dog Dominator 4-in-1 on like system, or any help as to if this drive will work properly in my system with Win 98 instead of the recommended Win 98 SE, or possible problems I could encounter? Thanks
