It fried your A4000 mobo? How do you know that it was the X-surfs' fault ? You didn't put an old 2.5" HD on it? The X-surf don't give enough amps (300 mA+) to spin them around.
I believe him. When my X-surf died, it crashed my A4000 VERY hard. Yellow-screen hardware error style. Audible popping in the sound output on the yellow screen, and several other hints that something went HORRIBLY wrong in my system. My first thought was that the motherboard was toast. Turns out that the only thing wrong was that the cheapo ISA card grafted to the X-surf had fried. I got lucky.
By the way, I was only using the network card part of it, anyhow. I don't have any IDE devices on the 4000. I run SCSI drives from the CyberStorm 060 SCSI option.
What do X-surf users think of the speed of their cards?
Mine was garbage. I never got it past about 900Kbit/sec. (110KByte/sec.), compared to about 8000Kbit/sec (1.0MByte/sec) from my old A2065 in the same computer.

Maybe I just had a bad X-Surf card to start with.... I ordered mine fairly early in the production run, and I have heard quality improved later on. But it left a very bad taste in my mouth, and I wouldn't trust another one in one of my machines.
