Bootable USB Floppy

I am looking into buying a new laptop, however it seems that laptops that come with both CD ROM and FLOPPY drives (internal) are gone? From what I am reading on these forums is that only SOME dell inspiron laptops can BOOT from the USB floppy drives. Can someone please list out which models have the capability (out of the box, without requiring a BIOS flash) to boot from a usb floppy. Thanks!
