The AX4BS Pro is a generously equipped board with provision being made for some of the most requested features from PC enthusiasts such such as 5 PCI slots and BIOS overclocking features.

The most notable absentee from the feature list is support for the legacy ISA slot standard. AOpen have followed the PC-99 specification here and have not decided to include it. There are no traces on the PCB for the inclusion of any ISA slots as an optional extra on any boards, with the lowest potion of the board being occupied by the CNR slot. This has been a standard trait of AOpen boards for some time.
