Added support for BUFFERSHIGH as alias to BUFFERS: No new code
but useful for people who are used to writing HIGH everywhere. Thanks to Christian Wallbaum the hint that config.txt had both. Removed code which called int 16.1 in a loop before 16.0 - this would only be useful if you invoke HLT before each int 16.1 ... git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@1366 6ac86273-5f31-0410-b378-82cca8765d1b

shows a note about that to inform the user that it does not use UMB.
