(*sigh*) And immediately after complaining about SRM v5.5's "funky" behavior driving a DE500-BA (21143-PC) talking to an FDX switch, I find the following admission in the SRM v5.6's release notes: "Bug fix to the Ethernet driver Fast Full Duplex Mode for the DE500-BA" I think it's time for me to upgrade SRM...
