I suggest, if you're not extremely rich, to try that Xsurf after you installed those 3.1 Roms. The big adcvantage of that network card is the extra IDE port on it, so you don't need to buy an extra IDE controller. Okay, you can not boot from that one but you can still boot from your internal scsi harddisc and use for example a cheap ultrafast cdrom that is connected to that IDE controller on the network card ...
