Ok, for some reason unknown to me, I can't recompile a kernel that is slimed down to only my network card drivers but still uses DHCP to access the internet. I'm a relative newcomer to freebsd, so I don't know all that much about what each individual option in my config files does. I have a 3com 3c90x (boomerang, XL, whatever you want to call it) using dhcp to acquire its IP address from my cable provider. When I recompile the kernel without most of the extra stuff, it does not run dhcp and therefore I have no internet (right now I'm booted off the generic kernel). I'm using FreeBSD 3.3. If someone wouldn't mind scanning my config file and telling me what i'm doing wrong, I would be very happy indeed. :-) machine "i386" cpu "I686_CPU" ident TWEEDMACHINE maxusers 64 #options MATH_EMULATE #Support for x87 emulation options INET #InterNETworking options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device [keep this!] options MFS #Memory Filesystem options MFS_ROOT #MFS usable as root device, "MFS" req'ed #options NFS #Network Filesystem #options NFS_ROOT #NFS usable as root device, "NFS" req'ed #options MSDOSFS #MSDOS Filesystem options "CD9660" #ISO 9660 Filesystem options "CD9660_ROOT" #CD-ROM usable as root.
