I couldn't figure out how to change the ISA bus speed on that PC so I tried a different 486/66 and SMC WD8013EPC. This other machine has a very different motherboard and the combo version of the ethernet card. With this hardware the default 2.2.5 ed driver usually causes a "Fatal trap 12: page fault while in kernel mode" at random addresses on FTP transfers. When it does work I get transfer rates around 40 KB/s. If I disable the 0WS option in the ed driver things work fine. Am I the only person experiencing this or am I just the only person still running old hardware? Phil Gilley pgilley@metronet.com
