Sounds like we should change the "and cx" mask to 5 so that if either EHDD
support or LBA is announced by the bios, the correct EHDD path will be
taken.

unload memdisk+FreeDOS => local boot
Sensei H. Peter Anvin,
I have successfully modified/enhanced memdisk so that one can chainload a
local operating system after running diskless FreeDOS.
I would like your advice regarding the appropriate interface for invoking
this functionality.
In addition, I would like to know what steps to take so that you feel
comfortable considering including this in the standard syslinux
distribution.
