For Narrow SCSI adapters, also called Fast and Ultra SCSI you want to use the following drivers. This includes the ABP915, ABP3922, ABP3925 and ABP3940UA adapters. These drivers MAY also work for older Advansys adapters that are not listed here and OEM adapters that use the Advansys chipsets. Please note that these adapters are natively supported by WinXP, so you do NOT need to install any drivers for these adapters under WinXP. (Do not force WinXP to install any other drivers or the adapters may not work correctly.)
