Hi, all I am having problems trying to config my 5.0-Release kernel for remote debugging. from the handbook below, http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html it seems to be as simple as adding a line like "device sio0 at isa? port IO_COM1 flags 0x80 irq 4" and "options DDB" to the kernel config file, except sio0 line doesnt actually work. when i tried config -g, it complains about "devices with zero units are not likely to be correct" I tried different combos such as leaving out device numbers with only flags. I also looked around the web and FreeBSD mailinglist but didnt find anything helpful. Is there a different way of enabling serial console for debugging? It also seems that the documentation on kernel config has gotten much worse since the 2.* days. Where was the helpful LINT file that explained all the options correctly? Thanks, Cheng
