Author: ion Date: Thu Jan 7 05:14:26 2016 New Revision: 70515 URL: http://svn.reactos.org/svn/reactos?rev=70515&view=rev Log: [BOOTLIB]: Cleanup some debug prints. [BOOTLIB]: Fix two big device I/O bugs (it's a miracle it worked) [BOOTLIB]: Use defined constants and comment some more device I/O code.
