bios multiboot CD

[dweidman]

Hello,
at my place of work we have accumilated many different model pc's over the years and I am interested in creating a multiboot CD where we can do BIOS updates to all the different machines with one utility disc.
Currently using magic iso to create the multiboot disc. All working well so far, but I have a bit of a snag, we are using some IBM Lenovo Thinkpad R61 laptops and their latest bios release is in the form a .FL1 and .FL2 file type along with some other files in the iso download. Well, magic iso does not understand these file types and returns a "no-emulation type image" when I point to these files to try and flash.
Is there a way to convert the .FL* types to say .bin or .img?

Thanks for any help.
