Interestingly, I had exactly the same problem yesterday on an Inspiron
8500.  Only I WAS booting from the network.

It is actually a memdisk issue, and it persists even in the latest
prerelease (2.05-pre2); I checked.

Unfortunately, the network boots also use memdisk :-(.  I got around
this by removing the DVD-ROM from the laptop's bay and putting in a
floppy drive instead.  Then I was able to boot from the network just
fine.

My guess is the same as yours: That the BIOS does not enable its
floppy support unless it notices that a floppy drive is actually
present.

This is more an issue for the SYSLINUX mailing list, and I will
probably bring it up there.  But meanwhile...

Do you have a floppy drive which you can insert temporarily?

If not, do you have a USB floppy drive which you can connect?  (If you
try this, be sure to flash your BIOS to the latest release first.  I
do not know whether this will work.)

Solving this long-term may require more drastic measures.  memdisk can
emulate a hard drive instead of a floppy, and I suspect that would
work here.  The only problem is that it will take up a drive letter
(presumably C:), meaning that the hard drive will be disk 2 (D:).
This will require changes to autoexec.bat, the way we invoke fdisk,
and probably a few other things.  It is starting to look like it will
be necessary, however.  I will try to find time to whip something
together this weekend, but my plate is already pretty full so I cannot
make any promises.
