Title: [Oscar-users] Oscar 4.2 and Marvell Lan
Hi Chris:
 
You have a few options:
 
1. Try the kernel from Peter Mueller: http://world.anarchy.com/~peter/systemimager/.  Hopefully it has built-in support for your gigabit interface (copy that to /tftpboot).
2. Upgrade the SystemImager version to 3.6.3 - this is an unofficial release though, but has worked well for others:
http://www.bcgsc.ca/downloads/oscar/systemimager/.  You'll need to rebuild a new image with the new SystemImager installed
3. Use the experimental feature of 3.6.3 - (Use Your Own Kernel) UYOK.  Provided that your headnode has the same hardware (i.e. the gigabit interface) as your compute nodes, you can run the following to generate a kernel/initrd.img pair which will allow you to netbook boot your compute nodes:
 
# si_prepareclient --server <servername> --norsyncd
 
Then copy the kernel/initrd.img file from /etc/systemimager/boot/ to /tftpboot, then you should be good to go.  You'll also need to up the ramdisk_size in /tftpboot/pxelinux.cfg/default's APPEND line, just add the following:
 
ramdisk_size=80000
 
Oh, and make sure that you have this RPM installed as well, as it is needed to generate initrd.img - http://www.bcgsc.ca/downloads/oscar/systemimager/systemimager-x86_64initrd_template-3.6.3-1.noarch.rpm.
 
Sounds like a lot of work yes, but hopefully one of the options will work.  Things will be much more easy with the release of OSCAR 5.0.
 
BTW, Fernando just checked in baseline support for Mandriva Linux 2006 x86 into trunk, so you should be able to get it working with x86_64 by simply rebuilding a bunch of RPMs and modifying a few files - if you have questions, please email Fernando and cc: oscar-devel on that.
 
Thanks!
 
Bernard

Subject: [Oscar-users] Oscar 4.2 and Marvell Lan

Hello,

I am trying to get a cluster of Intel Xeons / Redhat ES 4.0 / Oscar 4.2 working. The PXE boot does not work with the systemimager kernel in tftpboot. Is there anywhere I can find a kernel to work with this Marvell Gigabit Yukon PXE boot. I would have searched the mailing list because I think this question has been answered before but I can get the search feature to work on sourceforge.

My next project is to test the current sourcetree with mandriva x86_64.

Thank you,
