Cross compiling on AMD64 – the teaser Cross compiling is the act of compiling for one platform (e.g. i386) when on another (e.g. AMD 64). Why is this interesting to me? I have an AMD 64 3000+ with 1GB of RAM running on an ASUS A8V Deluxe1. It’s acting as my gateway right now. Needless …
ERROR: version of config(8) does not match kernel! I’ve seen this problem occur with other people when I was upgrading from 4.4 to 4.5. And now I’ve encountered this joy. Personally, I blame my not being on a bike since early December. That’s two months without a ride! In reality, I noticed that the FreshPorts2 …

Build world on your fast box, install on your slow box The build world process is used to upgrade FreeBSD from one version to another (e.g. 4.2-RELEASE to 4.2-STABLE). This process involves downloading source code, compiling it, installing it, and resolving any configuration file issues, although not necessarily in that order. The best place to …

SMP – using more than one CPU This rather short article is all about adding SMP to your kernel. Technically, SMP is symmetric multiprocessing. Practically, it means having more than one CPU. Such machines are faster than single CPU machines. In this article, I will assume you have a dual-cpu box. It’s not hard …
Installing 3.2-release [the hard way] This article details how I installed 3.2-release on a box which initially refused to take any 3.* versions but was quite happy on 2.2.8. The background I was given an old DEC box which had an onboard NCR PCI SCSI bus. I could install 2.2.8 on the box but not …
Kernel Configuration Options This section tells you where to find out about the various kernel configuration options. LINT All of the kernel configuration options are documented in /usr/src/sys/i386/conf/LINT. For example, if you open this file and search for ipfilter and you will find: # IPFILTER enables Darren Reed’s ipfilter package. # IPFILTER_LOG enables ipfilter’s …
Saving and using the kernel change information If you’ve ever installed FreeBSD, then you know about the visual configuration screen. This screen allows you to remove any hardware conflicts and to set the values of various system components. You can then save this information and continue the boot process. In short, this step allows …
compiling a kernel on another machine See also Build world on your fast box, install on your slow box, which also covers kernel building. One machine can compile a single kernel and distribute it to other machines if all machines contain the same version of the operating system. For instructions on how to create a …
Adding a second network card (and compiling a kernel) My FreeBSD box will act as a gateway. It will do this using two network cards. One card (ed0) will talk to the outside world. The other card (ed1) will talk to my subnet.. The system needs to know about the new device. There are two …
