Hi, Another good souce of references for programming the PC architecture across the full range of processors and system extensions (ie PCMCIA) is the 'PC Systems Architecture Series' of books put out by Addison-Wesley for MindShare, Inc. Mindshare also has various training courses and seminars. If interested (I am in no connected to them nor do I receive any $'s from them): BBS: 214-705-9604 mindshar@interserv.com CompuServe: 72507,1054 ____________________________________________________________________ | | | The financial policy of the welfare state requires that there | | be no way for the owners of wealth to protect themselves. | | | | -Alan Greenspan- | | | | _____ The Armadillo Group | | ,::////;::-.
