Updated CD-ROM files:

  1. slides\2.ppt
  2. slides\4.ppt
  3. slides\5.ppt
  4. slides\6.ppt
  5. slides\7.ppt
  6. libepc\*.* and ldscript\*.* (Both are required; see bug report)/
  7. programs\program2\*.*
  8. programs\program9\*.*
  9. The DJGPP compiler on the CD-ROM in the 1st printing of the text only works correctly under Windows 95, 98, and 98/2ed. An updated version of the compiler that works on all versions of Windows (95, 98, 98/2ed, NT, 2000, Me, and XP) and can be downloaded from http://clio.rice.edu/djgpp/win2k/main_203.htm. After installing the new compiler, be sure to run the LDSCRIPT program to create a new LINK.CMD file, recompile the library file LIBEPC.A, and recompile any .O object files. Then (and only then) should you try to link.
