At my previous employer we used Intel EEPro 1000 Server cards with the em(4) driver on FreeBSD 4.5 with nary a hitch and excellent performance. This was on ServerWorks chipset motherboards with P-III and P4 processors. > I believe that someone here recomended Tigon III based cards ... but I > was recently looking through 5.0-RELEASE's hardware notes and couldn't > find any mention of Tigon III. The follow-on to the Tigon II is the Broadcom BCM570x supported by the bge(4) driver in FreeBSD. This is not what you want. They're certainly cheap to test with, though; the Netgear GA302T sells for under $40 at a few online retailers. -- Where am I, and what am I doing in this handbasket?
