When I originally installed it, I opted to use the rpm. That was a mistake because even though it is for version 0.75-2 the contents and biosdisk script are actually for an earlier version. So I cloned the git tree and from http://linux.dell.com/git/biosdisk.git and installed from that, using the shell script. Then I used the -k option to specify the size of the disk image stored in /usr/share/biosdisk that I needed. Once I had that, I was able to flash the BIOS by selecting the grub menu choice for it. The only down side is that my "DMAR" problem is still not fixed for kernels more recent than 2.6.31.12-174.
