[syslinux] How to unload memdisk within DOS?

[Bernd.von.Osten at bccomponents.com]

Hi SysLinux,
i'm using pxelinux.0 and memdisk to successfully boot dos on my PXE capable
workstation.
But aber the DOS boot I need to get access to Drive A: again. My DOS
bootimage is putting all necessary stuff into it's own RAMdisk.
How can I disable memdisk, so that it releases drive A: (does not
necessarily free the allocated memory for it's RAMdisk ..)

with kind regards / mit freundlichen Grüßen
