OK, this makes no sense for more then one reason. If you need to boot from something to do a bios update, the fastest way would be to use the dos bootdisk. Dell usually offers most of their updates in multiple formats.

If you ran windows, i'd hope you wouldn't ask this question. So unless you run something strange/rare like haikuOS or BSD, you should look into just using the Linux.bin updater from inside your OS. Assuming you already have an active Linux OS, otherwise see step 1. To use those dell.bin updates, you need to get these dependencies.
If running x86 RHEL/CentOS/Fedora. Yum install libxml2 libstdc compat-libstdc-33 If running x8664 RHEL/CentOS/Fedora. Yum install libxml2.i386 libstdc.i386 compat-libstdc-33.i386 If you have something else going on, post more info. Otherwise I hope I could help.
