I can't remember if the Dell BIOS has this option, but some BIOSs allow
you to clear the PCI bus cache. That will trigger a full rescan of all
the cards that are attached and could get it listed in the boot process
again. If the BIOS doesn't have that option, you could try setting the
BIOS clear jumper.
