Windows 95/98/Me and Windows NT 4.0, No XP. LSI Logic ( old Symbios Logic )provides these drivers for the SYM20401/2/3 ISA cards and the 53C400A (HP version) card that was delivered with HP Scanners.
These drivers are not supported in anyway by LSI Logic. Any issues related to these drivers or controller cards will need to be addressed to HP. The use of the drivers is at your own risk. Technical Support is not available for the drivers or cards.
All other 53C400 or 53C400A interface cards are supported by the manufacturers of the devices (i.e. Scanner or CD-ROM). Contact them for drivers.
