The responses you're getting are driven by the fact that you appear to ascribe to octboot(4/octeon) the functionality to replace an x86 BIOS. octboot(4/octeon) is a driver (chunk of code) in the MIPS64 version of the OpenBSD kernel which lets an *already running* kernel replace itself with another kernel. An x86 BIOS is the code which bootstraps an x86 with particular memory and I/O setups, providing early services for access to that I/O and memory such that other stuff, like OpenBSD boot loaders, can themselves be invoked. These are completely different functions and neither can replace the other. I'm not sure what information led you to understand these to be similar functions, but boot sequences are among the most...specific pieces of system knowledge and while some people certainly start their approach from that angle, I suspect most people dig into that only after time spent on more portable (and frankly, usable) levels. Not knowing what your interests and energy are in, I can give no specific recommendation. Philip Guenther
