7.12. When my system booted, it told me that ``(bus speed defaulted)''. What does that mean?

7.16. I've got this neato kernel extension I just know everyone will will want. How do I get it included into the distribution?

8. Kernel Configuration

8.1. Ok, so how DO I compile my own kernel, anyway?

8.2. When I compile a kernel with multi-port serial code, it tells me that only the first port is probed and the rest skipped due to interrupt conflicts. How do I fix this?

9.2. How do I add a user easily? I read the man page and am more confused than ever!

9.3. <XXX> I'm trying to use my printer and keep running into problems. I tried looking at /etc/printcap, but it's close to useless. Any ideas?

9.4. My keyboard mappings are wrong for my system. How can I fix them?

10. Networking

10.1. Where can I get information booting FreeBSD ``diskless'', that is booting and running a FreeBSD box from a server rather than having a local disk?

10.9. I'm having problems with my NeXTStep machines and other FreeBSD ones accross PPP

11. Serial Communications

11.1. How do I tell if FreeBSD found my serial ports or modem cards?

11.2. Hey, I just upgraded to 2.0.5 and my tty0X are missing!

11.3. How do I access the serial ports once FreeBSD is running?

11.4. How do I configure the kernel for my multiport serial card?

11.5. I have two multiport serial cards that can share irqs. Can FreeBSD handle this?

11.6. What's the difference between ttyd1, ttyid1, and ttyld1? Or, how can I set the default serial parameters for a port?

11.7. How can I enable dialup logins on my modem?

11.8. How can I make my spare computer a dumb terminal connected to my FreeBSD box?

11.9. Why can't I run tip or cu?

11.10. My stock Hayes modem isn't supported---what should I do?

11.11. How am I expected to enter these AT commands without resorting to some DOS-based terminal program?

11.12. Why doesn't the @ sign for the phone number capability work?

11.13. How can I dial a phone number on the command line?

11.14. Great---but how can I do that without having to specify the bps rate on the command line?

11.15. I want separate entries for various hosts I access through a terminal server, but I don't want to type ``CONNECT <host>'' each time once I'm connected. Can tip do that for me?

11.16. My university has 42 billion students but only 4 modem lines. Can tip automatically try each line?

11.17. How come I have to hit CTRL+P twice to send CTRL+P once?

11.18. Suddenly everything I type is all UPPER CASE. What gives?

11.19. How can I do file transfers with tip?
