Tonight I pulled the 4000D down to install 16MB on the mobo. Way back a long time ago I had pulled the 16MB off because I had been told (erroneously, unless it varies by accelerator) that the 16MB would be higher priority than memory on the accelerator.
I told you that to tell ask you this. When I booted up and checked on the system (happily finding 144MB FastRAM) I noticed that the X-Surf reports as Zorro II. Even though PCI expansion boards probably make this a moot point, I pondered as to whether a Zorro III X-Surf would be fast enough to support 100Mbps, or at least fast enough to fake it?
