I have compiled a new kernel and it has become huge. It is 3 times the size of the GENERIC kernel. Below is the config file for a kernel called BOB. I apologize for the size of this message. I am quite a newbie, so please be gentle. ;-) FWIW, I have left almost all the comments in the file and I have no scsi devices. A quick question at this time; is it okay to delete all the device lines and comments that are not required? What is the proffered method? # # BOB new kernel # # # $Id: BOB,v 1.0.0.0 2000/06/13 11:05:05 $ machine "i386" #cpu "I386_CPU" #cpu "I486_CPU" cpu "I586_CPU" #cpu "I686_CPU" ident BOB 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.
