The jumper settings are an ugly mishmash, trust me, I used to like jumper settable cards but with SMC changing the settings every other revision of card, it rapidly becomes a stinking pile of doo doo. > >>OK, how 'bout this: I'll endorse nuking the ed1 device, but only if the > >>default settings for the ed0 device are changed to 5/300 in GENERIC.

The ed driver, in my opinion, is by far the most popular Ethernet driver, and having two interfaces available makes it very easy to rapidly do things like toss a second network interface in a machine, build an "emergency router", etc. without the downtime required to rebuild a kernel on a 386DX/40 with 8MB of RAM (which takes a LONG time). However, I will definitely scream if anyone removes sio2/sio3. Disabled by default, MAYBE. Removed, NO. I have seen far too many people who have three or four STANDARD SERIAL PORTS and sio2/3 directly map to COM3/4. There should be NO reason to screw around with this. These lines support standard PC hardware. If you remove them, remove sio1 too because you obviously only need one serial port to do an install. The harder we make it for people to use out of the box, the more like Linux we become. I see the argument for simplicity, and I understand -c, but you also have to realize that people who install GENERIC SunOS, GENERIC NetBSD, or whatever Linux calls its default get a fully functional system. I fail to see what dropping sio2/sio3/ed1 buys anyways, since these device drivers are already required by sio0/sio1/ed0. I assume it might save a FEW bytes in kernel size for the extra entries. BIG stinkin' deal. That's a small price to pay for making it work the way people would expect. ... JG
