Hello SomeGuy, The latest bios update can be found here: Since your machine has a CD-RW drive, follow the instructions for the CD ISO image version. You should be able to update your model no. When applying the update. If this doesn't work, have a look at this thread: Note the link to HMD 1.75 (I hope it still works). Try running it from a CD-RW since you don't have a floppy. If my links don't work: 1.
The bios for your box can be found by entering your product no. (6418-13U) on the 'Support & downloads' page.

Can be found by entering the following search terms: 'update serial number bios' in the search box on the main lenovo community page. Hope this helps.
