I've found a couple of good references on upgrading the kernel. But what if I'm happy with the kernel I already have and just want to add APM? Does anyone know of a good documentation specifically for this?

Thanks,

I thought APM is installed by default with Fedora Core 1?

$ apm -v
APM BIOS 1.2 (kernel driver 1.16)
AC on-line, no system battery

Well I have a Dell Inspiron 5100 and APM won't work with it. I just found this out.

I'm following the instructions found http://cabibbo.physics.wm.edu/~bryan...piron5100.html but when I patch the osl.c I get this error:

Hunk #1 succeeded at 69 (offset -1 lines).
Hunk #2 FAILED at 220.
1 out of 2 hunks FAILED -- saving rejects to file osl.c.rej

Then I go ahead and try and compile the kernel I get this error:

acpi_dsdt.c:793:66: warning: multi-line string literals are deprecated
acpi_dsdt.c:793:66: warning: null character(s) preserved in literal

Any ideas?

The kernel that comes with RedHat and Fedora is known to be not compatible with the one from kernel.org. RedHat has enhanced the stock kernel to include some of those advance features which most probably will be available in 2.6 version.. hence, you may have difficulties in compiling your own kernel.
However, if you want to continue trying, you may want to look into the .rej file and apply the patch manually by hand into osl.c file. Follow exactly the instructions found in the website given by you and hopefully it works for you.
