I'm attempting to patch my Redhat 9 kernel to setup ACPI support for my Picturebook (yea, I did my first Lunix install on a Sony Picturebook, I'm a massochist.)

ls /usr/src/ only lists 'debug' so I figured I had to download and install the kernel source. I used uname to find my kernel version and processor:

$ uname -rm
2.4.20-8 i686

and downloaded and installed this rpm:

kernel-2.4.20-8.i686.rpm

by double clicking on it. It seemed to install fine but /usr/src still only had 'debug' in it! I think the rpm installed a bunch of files in /lib/modules/2.4.20-8 but I can't seem to be able to use the patch command in there? How do I get a subdirectory like /usr/src/linux-2.4.20-8

you need to install

kernel-source not kernel

Thanks nakkaya, why am I having such a hard time finding

kernel-source.2.4.20-8.i686.rpm? I can't use i386, can I?

you can use i386 the source code is a collection of text files so it realy doesnt matter if it is 686 or 386 but you can always use 386 on a 686 machines for binary files. cpu s are backward compatible so 486 can run 386 code and 686 can run 386 code

Thanks again. I'm trying to install kernel-source-2.4.20-8.i386.rpm from the second disk of the RedHat 9 install CDs but now I have to work through a gcc dependency...

Thanks nakkaya. I booted up the installer CD, installed the kernel source, gcc, tcl, and tk. I rebooted, applied the patch, recompiled the kernel and APCI works perfectly. My Picturebook is no longer a toaster oven (man would that thing get HOT!) Now I just have to figure out why my wireless PCMCIA card is totally dead (no lights). I can't remember what I had to do to get it working in the first place but I'll post another thread on that if I get stuck.
