This is what an older README file says -
3.2   Step by step instructions for extracting the Linux update
                   files.

                   - Run the "IBM eserver xSeries 235 Linux BIOS Update"
                     with the following command line:
                     
                        "./<update>.sh -x <path>" where <update>.sh is the
                        downloaded update and <path> is the path to which the
                        Windows update files will be extracted.
                       
                     NOTE: The following message is shown on RedHat Enterprise Linux 3.0
                     and other distributions that do not install the compatibility libstdc++
                     library.
         
                        ./lflash: error while loading shared libraries:
                        libstdc++-libc6.1-1.so.2: cannot open shared object file:
                        No such file or directory.
                         
                     If the above message is shown, install the compat-libstdc++*.rpm that was
                     included on the distribution media.
                       
                   - The files extracted are all the files that are necessary to
                     perform a BIOS update under Linux.  Run "./lflash" from a
                     command line to update BIOS.

You don't need a floppy or usb.
Just create a directory to store the extracted files and start the update process from there.
mkdir /tmp/pme175c
./ibm_fw_bios_pme175c_linux_i386.sh  -x   /tmp/pme175c
cd  /tmp/pme175c
./lflash  
........
rm  -r /tmp/pme175c  # or keep the directory and its contentsfor future reference

Just over-install the desired version. Older versions are available from where you got the one you're going to install now.
If the system fails to restart due to a severe error during BIOS update follow page 18 of this guide -

Commented:
For 64 bit you need to install the 32 bit libraries.

On Ubuntu:
sudo apt-get install ia32-libs
