"Some people" don't know what the hell they're talking about.
By and large, any hardware that will work on Win9x will work on XP, SCSI or otherwise. You will need a different driver, one written for Win2K/XP, but aside from that it makes no difference what the physical connection is to the computer.
i would like to move from win 98 to xp, but my scanner has a scuzzy card runing it. It is an epson perfection 636. some people tell me it wont work, some say it will.I just dont know what to go by anyboy have any ideas.
thanks
