Theoretically, it's possible, but it would be different for every BIOS implementation (and version, to a greater or lesser extent), and it isn't generally useful. FreeBSD doesn't depend on the BIOS after booting is complete. -- Lowell Gilbert, embedded/networking software engineer, Boston area: resume/CV at http://be-well.ilk.org:8088/~lowell/resume/ username/password "public" ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
How to view BIOS settings on a running system?
Hi, A few times I have seen answers to problems like: "Verify this-and-this in your BIOS setting" The only way to do this, that I know of, is to shutdown the system and hit the DEL-key at boot up etc. But this is a bit silly, for just checking a particular setting of the BIOS. Isn't there a tool in FreeBSD that shows the BIOS settings in a similar layout, without shutting down the system? I assume the kernel can access the BIOS and read all its settings, or is this impossible?
