I have a D630 at work and I want it use it to generate the 802.3 test patterns. I know the broadcom NIC can do this as there is a control register to do this (page 615 of the BCM57xx user guide). So how do I write to this register? Broadcom have an application called b57dia.exe but when I run it, it reports it can't find a Broadcom device. Broadcom are not being very helpful and said to contact Dell. Any suggestions?
