Introduction

Although we do not plan to run our PC/104 computers using remotely mounted file systems, it was useful to try to boot Linux PC/104 remotely. I followed what DAQ group did for the ROC booting where this is expected to be the main mode of operation due to a very large number of ROCs.


Setup

To set up the networking booting using PXE I use Bryan Moffit's instructions on how to boot Linux using DHCP/TFTP server. Bryan gave us (and Hall B) the CentOS 5.5 kernel which we put on somov-l1 machine.

At first, we thought that it would be good to use /group/halld area to boot Linux remotely, but after the cyber event it was not clear how useful and reliable it is going to be to require NFS mounting capability from some development subnets like the 36-subnet. So we decided to keep both the TFTP server and the root file system on somov-l1 until we buy a server in fall of 2011.
