Hi All,
I have a few basic questions regarding building a custom Kernel:
(1) Once I configure, make and make install the custom kernel... it will get written
to /boot/kernel. Now I have already made a backup of the working kernel. what I need
to know is when I get the boot loader menu(when it counts from 1 to 10) is there any
way in which I can Include another option for my Custom Kernel. I want the default to
remain as the working kernel... and I want an option for my Custom kernel in the
menu...
(2) Secondly I dont understand the boot prompt and the loader prompt completely. at
the boot prompt I guess I can specify the kernel I want to load. So lets say I have my
custom kernel in the directory /boot/mydir/custom-kernel. so how do I specify at the
boot prompt or the loader prompt to load the custom kernel
(3) And finally I had downloaded the source code of freeBSD and I configured, did a
make and a make install without making any changes ...(Just to get it started!) ...
when I rebooted the system it failed to recognize the disk and so I reinstalled
FreeBSD again...( hadnt enabled any debug options so could not recover any
information!!)... Is there anything that "HAS" to be done before installing the new
kernel?
I'm working on FreeBSD 5.2...
any help will be appreciated.
I recommend you check out the FreeBSD handbook, developer's handbook and/or
architecture handbook or even read the comments in src/Makefile. The answers are all
in there.
I guess the version you installed must be R5.1/R4.10 or even earlier versions. R5.2
and later versions have serious problems recognizing hardwares. It turnes on many new
features (ACPI, SMP etc.) in the kernel configuration by default. However, the new
code doesn't work for certain motherboards and chipsets, at least for now. In one case
that I know is that the APIC and IOAPIC interrupt controllers can not be correctly
initialized, which fails the device auto configuration process or causing other
serious problems after the system is up (like interrupt missing).
If your hardware doesn't work for the 5.2, stick to R5.1 or 4.10 would be a better
idea.
Hope it helps.
