[syslinux] Memdisk problem when no hard drives are in system

[Mike Nolterieke]

Hi,
  I am having a problem where an 8MB DOS PXE image that I use with memdisk
to update the firmware of my systems does not boot when there are no (or
failed) hard drives in the system.  This process normally works fine but I
get this error message "=Nf000f859 Failure, assuming this is the only
drive" followed by "Non-System disk or disk-error" when the hard drives are
missing or have failed.

Any ideas on what is going on?

Mike
