The following files(by product type) make up the product's drivers in Windows XP:
Most PCI Cards
ACCES32.dll, ACCESNT.sys, PCIFind.exe, NTioPCI.sys, AIOWDM.dll, AIOWDM.sys, ACCES.inf Note: Serial Communication (COM) cards also require Ports.inf. Note: Eight (8) channel PCI (COM) cards also require PCI8S.sys.
Also note: It is now possible to operate our non-COM PCI product line using only AIOWDM.dll, AIOWDM.dll, and ACCES.inf. The above drivers / utilities are only necessary for compatibility with the existing generation of sample programs.
