Only PCI and on-board ISA peripherials are supported at this time. This support has been only lightly tested due to a lack of response to my call for testers on the freebsd-alpha mailing list. It works quite well on the one AS2100 on which it has been tested, but it may not work on an AS2100A and should therefore be regarded as experimental.
