No, it's a generic NE2000-clone PCI card. The combination NE2000 + NCR810 card works fine with the sahred IRQ5 (I've just checked again). (Well, "fine" is a bit optimistic. If I really beat both of them [cvs update from an NFS repo to a fast disk on the NCR], I = get device timeouts, but generally it works.) -- Stefan Bethke Promo Datentechnik | Tel. +49-40-851744-18 + Systemberatung GmbH | Fax. +49-40-851744-44 Eduardstrasse 46-48 | e-mail: stefan@Promo.DE D-20257 Hamburg | http://www.Promo.DE/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
