   1 This is some preliminary information on using PICE. I am planning to write
   2 a detailed manual later.

   6     PICE for Reactos is in early beta stage of development. It still has many bugs.

  11 PICE is a kernel debugger that was ported for Reactos (the original Linux
  12 project by Klaus P. Gerlicher and Goran Devic may be found here:
  13 http://pice.sourceforge.net).
  14
  15 Installation and use:
  16
  17 1. PICE is loaded like a regular device driver. The only limitation - it must
  18 be loaded after keyboard.sys driver. You should add:
  19
  20    LdrLoadAutoConfigDriver( L"pice.sys" );
  21
  22 in ntoskrnl/ldr/loader.c after the line loading keyboard driver.
  23
  24 2. You should copy pice.cfg and ntoskrnl.sym to \SystemRoot\symbols directory
  25 of Reactos.
  26
  27 3. If you want to add symbolic information you should use loader.exe to
  28 create .dbg file from the unstrippped version of exe or driver:
  29 For example:
  30 pice\loader\loader.exe -t ntoskrnl.nostrip.exe
  31
  32 After that copy .dbg file to \SystemRoot\symbols and add a line to pice.cfg:
  33 \\SystemRoot\symbols\ntoskrnl.dbg.
  34
  35 Pice will load the symbols during boot. For large .dbg files it may take a
  36 while (ntoskrnl.dbg is ~3Mb). You may find that loading time under bochs is
  37 quite slow, although otherwise performance should be fine.
  38
  39 Key combination to break into debugger is CTRL-D.
  40 You may need to press CTRL button upon return from the debugger if you get
  41 "funny" symbols when you type.
