Re: [K12OSN] request for k12ltsp kernel .config file....was linuxprogress patch

well, I guess I need a bit of detail...

I decided to just get a kernel to boot, that was custom compiled, that did not have lpp in it, so I can just see if I'm doing things right.

so, I have the source, installed in /usr/src/linux-2.4.18-ltsp
i got the config file from the ltsp_initrd_kit,
I did make xconfig, and loaded the config file(renamed to .config)
I then saved, and exited.
make dep;make clean;make -j3 bzImage;make modules;make modules_install

then, I took the resultant bzImage,
and from the ltsp kernel howto,
I did
mknbi-linux --rootdir=/tftpboot/lts/pxe --ipaddrs=rom \
/usr/src/linux-2.4.18-ltsp/arch/i386/boot/bzImage > /tftpboot/lts/pxe/vmlinuz-2.4.18-nolpp

then I changed the /tftpboot/lts/pxe/pxelinux.cfg/default file to read:
label linux
 kernel vmlinuz-2.4.18-nolpp
 append root=/dev/ram0 rw init=/linuxrc

which is what was therebefore, minus the ramdisk entry, and the kernel name different...

now, I would assume that the pxe booting client would need a ramdisk, bu tI don't see in the howto where it says to generate one, unless the mknbi part is doing that...

All I get is a screen full of colored ascii characters...

now, when I take the kernel without the mknbi, and just copy the bzImage to /tftpboot/lts/pxe, and point the default file to that, it boots further, then freezes(because of drivers, or ramdisk situation), but it goes further than the mknbi one.

What am I doing wrong.....
or better question, what is my thick head missing on the boot procedure...?

Can you detail the steps to getting custom kernels to boot with PXE?

Can we get the .config file for the ltsp kernel? We believe this to be the root of our problem. We would like to take the .config file for the kernel that was compiled for k12ltsp, and apply the lpp patch to it, and see where we get.

I don't compile my own terminal kernels, I use the stock LTSP versions.

There is a HOWTO on the ltsp.org site:


Also, what needs to be done to a k12ltsp kernel, vs. a regular ltsp kernel...
is there anything different?
We are using PXE...

Do you use the ltsp_initrd_kit to prepare the stock k12ltsp kernel?

I actually do the reverse for making the PXE kernels. I take the BOOTP
version of the kernel that LTSP ships and I strip out the plain kernel and
the initrd.

I won't go into detail since it's really arcane and doesn't answer your
