An all > round positive experience :-) It would be nice to remove my Comtrol Rocketport serial card, and the 8 serial cables leading across the middle of the room to my shelf of machines and replace it with one firewire cable leading to a firewire hub. But, as a firewire newbie, I have some questions: 1) Is any firewire PCI adapter just as good as any other in terms of performance, and FreeBSD support? (prices seem to range from $10 to $100) 2) Is dcons usable after a panic (ie, DDB or KDB_TRACE)? Or is it only usable for remote-gdb? 3) Is dcons endian and pointer-size agonstic? Can I run consoles to an amd64 and a powerpc box from an x86? 4) Does the loader know about dcons? Eg, can I do "unload boot kernel.test" using dcons? Thanks, Drew
