Classic mac fun (and some questions)

Here's what I see: Control Panels -> TCP/IP (AOL) This works. Is set it to ethernet and manually and plugged in good values. Control Panels -> Appletalk I set it to ethernet. It says "current zone: no zones available" Control Panels -> Apple Remote Access not setup correctly. please install from the disk and try again. I found file sharing and turned it on. I'm unable to ping the quadra from another machine on the network, but I do get a light on the hub. Apple file exchange works, but neither floppy drive that I have works. Writing apple disk images from a usb floppy appears to not work. I have another machine I plan to get going this weekend that has a floppy drive and a real disk controller. I'll try it from there. And to make matters worse, I noticed that there was an 8.1 installation in a separate system folder. I found the system folder picker and switched it to the 8.1 folder. Now the machine won't boot. I just get the happy face. Is there some bootup key combination that can undo this? brian
