stack=size Set the stack to "size" bytes
+h) Some systems without a floppy drive have been known to have
+ problems with floppy images. To avoid that those problems, first
+ of all make sure you don't have a floppy drive configured on the
+ BIOS screen. If there is no option to configure that, or that
+ doesn't work, you can use the option:
+
+ nopass Hide all real drives of the same type (floppy or hard disk)
+ nopassany Hide all real drives (floppy and hard disk)

Some interesting things to note:
If you're using MEMDISK to boot DOS from a CD-ROM (using ISOLINUX),
you might find the generic El Torito CD-ROM driver by Gary Tong and
-Bart Lagerweij useful:

-
+Bart Lagerweij useful. It is now included with the Syslinux
+distribution, in the dosutil directory. See the file
+dosutil/eltorito.txt for more information.
Similarly, if you're booting DOS over the network using PXELINUX, you
can use the "keeppxe" option and use the generic PXE (UNDI) NDIS
