  52. WINDOWS WON"T LOAD WHEN S-ICE IS PRESENT
  -------------------------------------------------------------------
  Solution:
	Make sure BREAK is OFF inside Soft-ICE
	Put a /M:1 after HIMEM.SYS in CONFIG.SYS

  -------------------------------------------------------------------
  53. REGISTER WINDOW OVEWRITTEN WITH DS:XXXX IN LOWER RIGHT	
  -------------------------------------------------------------------
  Problem:  The FLAGS in the register window are overwritten by
  a referenced memory address ( DS:XXXX= ).
  Solution:
	Patch S-ICE.EXE as follows:

	ren s-ice.exe s-ice.bin
	debug s-ice.bin
	-s cs+1000 lffff E8 91 FC
	  ( prints out an address in xxxx:yyyy format )
	-e xxxx:yyyy 90 90 90
	-w
	-q
	ren s-ice.bin s-ice.exe

   -----------------------------------------------------------------
   54. SOFT-ICE DOES NOT POP UP PROPERLY WHEN RUNNING BRIEF
   -----------------------------------------------------------------
   Problem: When running BRIEF ( editor is actually on screen ), 
   CTRL-D causes the machine to beep and a reboot is needed.

   Solution: This is a problem that occurred since 2.7 and the addition
   of 43 and 50 line mode.  An extra video page is being used and
   an equation in Soft-ICE was producing a negative result.
   Patch s-ice.exe as follows

	ren s-ice.exe s-ice.bin
	debug s-ice.bin
	-r
	-s cs+1000 lffff 66 2B CE F3
	  ( prints out an address in xxxx:yyyy format )
	-e xxxx:yyyy 90 90 90
	-s cs+1000 lffff 66 2B CF
	  ( prints out an address in xxxx:yyyy format )
	-e xxxx:yyyy 90 90 90
	-w
	-q
	ren s-ice.bin s-ice.exe

    ---------------------------------------------------------------
    55. USING SOFT-ICE WITH QL10DOS.SYS
    ---------------------------------------------------------------
    Problem:  When SL10DOS.SYS is loaded, you get errors on disk
    accesses.  QL10DOS.SYS is a new driver being shipped for SCSI
      hard disks.

      Solution: You must load drivers in CONFIG.SYS in the following
      order-
		device=s-ice.exe
		device=ql10dos.sys
		device=himem.sys
		device=funnel.sys

  *******************************************************************
  The following apply to Versions 2.62 and EARLIER ONLY !!!!
  *******************************************************************

  -------------------------------------------------------------------
  56. FLOPPY HANGS WHEN SOFT-ICE INSTALLED (GP ERROR IN CACHE)
  -------------------------------------------------------------------
  Problem: Floppy hangs when Soft-ICE is installed, on protected
  mode instruction in BIOS (F000:xxxx). Instruction is MOV EAX,CRx.
  Analysis: Some older Phoenix BIOS ROM's handled cache operations
  in protected mode. BIOS ROM must be replaced or you must update to
  Soft-ICE 2.6+, which emulates this instruction without generating
  a protection error. Some Gateway 2000 486's have this older BIOS.

  -------------------------------------------------------------------
  57. TURBO DEBUGGER IN 43-LINE MODE
  -------------------------------------------------------------------
  Problem: Soft-ICE with Turbo Debugger in 43 line mode beeps and
  dies.
  Solution: patch s-ice.exe as follows:
   ren s-ice.exe s-ice.bin
   debug s-ice.bin
   -r       (get value of CS register)
   -e (cs+1000h):b993 7f
   -w
   -q
   ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  58. WRONG LINE #'S IN "STACK" COMMAND
  -------------------------------------------------------------------
  Problem: Line numbers displayed by STACK command are wrong,
  typically very large (28xxx)
  Solution: patch s-ice.exe as follows:
	ren s-ice.exe s-ice.bin
	debug s-ice.bin
	-e cs:626f
	   (should print "08.")
	   0a             (change 08 to 0a)
	-w
	-q
	ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  59. GP ERROR DISASSEMBLING OR STEPPING THRU CODE
  -------------------------------------------------------------------
  Problem: General Protection Error when disassembling or stepping
  thru code.
  Solution: patch s-ice.exe as follows:
  ren s-ice.exe s-ice.bin
  debug s-ice.bin
  (Note: in newer versions search from CS+1000)
  -r
  -s cs:0 lffff 81 7c 01 4e 56 74
  (prints address in xxxx:yyyy format; offset should be E3D8)
  -e xxxx:yyyy 90 90 90 90 90 90 90 90 90 90 90 90 90 (13 NOP's)
  -w
  -q
  ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  60. "ENTER PATH..." FOR BORLAND C++
  -------------------------------------------------------------------
  Problem: Prints "enter path for" for all source files.
  Solution: Patch LDR.EXE as follows:
	 ren ldr.exe ldr.bin
	 debug ldr.exe
	 -e 8cec
	  02. 03         (change 02 to 03)
	 -w
	 -q
	 ren ldr.bin ldr.exe

  -------------------------------------------------------------------
  61. USING SOFT-ICE 2.60 & EARLIER WITH MSVC or BORLAND 3.1
  -------------------------------------------------------------------
  Problem: Can't load a MSVC or BORLAND 3.1 program into Soft-ICE
  Solution: To be compatible with MSVC or BORLAND 3.1, you must have
	version 2.62 or higher.

  -------------------------------------------------------------------
  62. USING SOFT-ICE 2.5x & EARLIER WITH MICROSOFT C/C++ 7.00
  -------------------------------------------------------------------
  Problem: With the C/C++ 7.00 compiler, Microsoft changed the
	   format of the CodeView debug data.
  Solution: Soft-ICE cannot read the C/C++ debug data directly
  from the .EXE file. Use the MSYM method as follows:

  Link without the "/CO" switch but with the "/MA" and "/LI"
  switches.
  After linking, run our MSYM.EXE utility on the .MAP file to
  create a .SYM file which contains the debug data.

  If there is no debug data in the .EXE file, Soft-ICE will look
  for a .SYM file.

  You should use MSYM version 2.4 (dated 8/24/92) or later; it can
  be downloaded from this BBS. Earlier versions may work in some
  cases.
  NOTE: Microsoft's MAPSYM utility may create a .SYM file as part
  of the compilation process. This .SYM file does not contain all the
  debug data needed by Soft-ICE. You must use our MSYM.

  -------------------------------------------------------------------
  63. BPM BREAKPOINT REBOOTS (SOFT-ICE VERSION 2.60-2.62)
  -------------------------------------------------------------------
  Problem: BPM breakpoint with R verb or with any conditional
  qualifier reboots the system when the breakpoint occurs (Soft-ICE
  Version 2.60 - 2.62).
  Solution: When a Soft-ICE source file was modified so that it
  also could be used for Soft-ICE/W, some code which handled hardware
  breakpoint re-entrancy was accidently deleted.
	During the handling of a BPM breakpoint, if the "R" verb was
  chosen or if there is a conditional qualifier, the contents of the
  breakpoint location are read. Reading this address causes another
  breakpoint to be generated, which re-enters the breakpoint handler
  and reads the location again, causing still another, and so on
  until the stack overwrites something and the system reboots.
	To fix this, patch S-ICE.EXE as follows:

   ren s-ice.exe s-ice.bin
   debug s-ice.bin
   -s 0 lffff f7 46 30 02 00 0f 85 00 00
	 (prints an address in xxxx:yyyy format)
   -e xxxx:yyyy     0f 21 f0 66 50 66 33 c0 0f 23 f0 66 58 a2 64 01
   -e xxxx:yyyy+10  a9 00 40 0f 85 a0 00 f7 46 30 02 00 0f 84 92 ff
   -w
   -q
   ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  64. BORLAND 4.0 PROGRAMS DO NOT LOAD INTO SOFT-ICE
  -------------------------------------------------------------------
  Problem: Can't load source or symbols for Borland 4.0 problems
  Solution: Soft-ICE versions 2.62 and lower cannot handle Borland 
  4.0 symbols.  The only solution is to upgrade.

  -------------------------------------------------------------------
  65. SNOW ON SCREEN WHEN USING WINDOWS (REAL MODE)
  -------------------------------------------------------------------
  Problem: Snow on screen when using Soft-ICE with Windows 3.0 in
  real mode.
  Solution: Increase the Windows space by decreasing the /TRA and
  /SYM space used by Soft-ICE.

  -------------------------------------------------------------------
  66. LOADING IN OVER 16M MEMORY OR 16M MEMORY NOMINAL
  -------------------------------------------------------------------
  Problem: Over 16M memory, keeps rebooting when trying to install
  Solution: patch s-ice.exe as follows:
	 ren s-ice.exe s-ice.bin
	 debug s-ice.bin
	 -s 0 lffff b4 88 cd 15
	 (prints 2 addresses in xxxx:yyyy format)
	 -e first-address b8 00 3b 90
	 -w
	 -q
	 ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  67. COMPAQ REBOOTS WHEN TRYING TO LOAD SOFT-ICE
  -------------------------------------------------------------------
  Problem: SL based/non-BIMM Compaq system reboots when s-ice.exe is
	   installed.
  Solution: change s-ice.exe as follows (NOTE - the syntax "cs+2000"
  means add 2000 hex to the contents of the CS register and key in
  this number):
	 ren  s-ice.exe s-ice.bin
	 debug s-ice.bin
	 -s 0 lffff '03C'
	 (prints an address in xxxx:yyyy format)
	 -e address ff
	 -r        (get CS)
	 -s cs+2000:0 lffff '03C'
	 (prints an address in xxxx:yyyy format)
	 -e address ff
	 -w
	 -q
	 ren s-ice.bin s-ice.exe

   Also, if the keyword COMPAQ is in the S-ICE.DAT file, comment it
   out with a semicolon.

   NOTE: This problem has also occurred on other brands of computer
   which used a Compaq BIOS to control an IDE disk drive.

  -------------------------------------------------------------------
  68. USING SOFT-ICE ON A PENTIUM SYSTEM
  -------------------------------------------------------------------
   The following changes must be made when using Soft-ICE on a
   Pentium system (NOTE - the syntax "cs+2000" means add 2000 Hex to
   the contents of the CS register and key in this number):

	 ren  s-ice.exe s-ice.bin
	 debug s-ice.bin
	 -r        (get CS)
	 -s cs+2000:0 lffff 2e 83 06
	 (prints an address in xxxx:yyyy format)
	 -e address 64
	 -s cs+2000:0 lffff 2e c7 06
	 (prints two addresses in xxxx:yyyy format)
	 -e first-address 64
	 -w
	 -q
	 ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  69. LDR HANGS WHEN LOADING SYMBOLS
  -------------------------------------------------------------------
  Problem: LDR.EXE hangs when loading symbols or the symbolic
  names are all junk characters.
  Solution: LDR stores the symbolic names in 5K blocks for parsing
  to extended memory. When a block is filled, there is no check for
  the end of the symbols, so if the last name exactly fills the last
  block, LDR continues processing and hangs. The following patch
  inserts a check for the symbol count = 0 at the end of a block.

  ren ldr.exe ldr.bin
  debug ldr.bin
  -s 0 lffff 0f 8f 05 00
  (prints an address in xxxx:yyyy format)
  -e xxxx:yyyy 77 05 e2 e8 eb 1b 90 49 e3 17
  -w
  -q
  ren ldr.bin ldr.exe

  -------------------------------------------------------------------
  70. BAD PRINTOUT OF SOURCE LINES IN BACK TRACE
  -------------------------------------------------------------------
  Problem: Source lines sent to printer when printing back trace
  buffer are blank or all 0F characters.
  Solution: Source lines are routed through a routine which puts
  the actual character in AH, and puts 0F into AL The printer routine
  reads the contents of AL. To correct this, patch S-ICE.EXE to swap
  AL and AH when AL = 0F, as follows:

  NOTE: This patch begins at the address + 2, i.e., at the "ee"

  ren s-ice.exe s-ice.bin
  debug s-ice.bin
  -s 0 lffff 3d 4a ee
  (prints an address in xxxx:yyyy format)
  -e xxxx:yyyy+2  3c 0f 75 02 88 e0 ee b9 05 00 e2 fe 42 bb a0 00
  -e xxxx:yyyy+12 ec 51 b9 05 00 e2 fe 59 a8 80 75 07 e2 f2 4b 74
  -e xxxx:yyyy+22 1b eb ed b0 0d 42 ee b9 05 00 e2 fe
  -w
  -q
  ren s-ice.bin s-ice.exe

  -------------------------------------------------------------------
  71. BACK TRACE PRINTOUT HAS LONG BLOCKS OF SPACES
  -------------------------------------------------------------------
  Problem: While printing the back trace buffer, long blocks of
  spaces are printed when a field overruns into the next field.
  Solution: Patch S-ICE.EXE as follows to print a single space
  if a negative or zero count results when calculating the number of
  spaces to get to a specific column:

  ren s-ice.exe s-ice.bin
  debug s-ice.bin
  -r              (get contents of CS register)
  -s cs+1000:0 lffff d0 e4 d0 e4 d0 e4 d0 e4
  (prints an address in xxxx:yyyy format)
  -e xxxx:yyyy    c0 e4 04 0a c4 8a c8 b5 00 2a 0e e3 3f 7d 03 b9
  -e xxxx:yyyy+10 01 00
  -w
  -q
  ren s-ice.bin s-ice.exe
