BSOD Code Information

Whether you know it or not, the "stop code" in the BSOD means something very useful. If you are new to all of this, read below for what they mean.

F002 - Memory Parity Check

• Write down the number from the BSOD.
• Add 384 (upper memory block)
• Divide result by total "k" bytes of memory installed in machine (this should be the number displayed durring a good normal bootup).
• The result will be an integer and remainder.
  
  
  • The integer number will be the slot number in the machine, that the problem memory is installed.
  
  
• If the problem is intermittent, you can edit the boot.ini file to add a "/maxmem" flag, to zero in on the bad SIMM/DIMM.

0000001E

• If rdr.sys (usually in end of 2nd column) is present :
  
  
  • your problem is a bad network adapter
  
  
• If fastfat.sys or ntfs.sys is present :
  
  
  • run "chkdsk /f", the allocation unit was clobbered
  
  

0000000A

• Apparently, you have installed new hardware -
• There is a device conflict -
  
  
  • run "hqtools" and track down the bad values
  
  
• Just a tip - disable EPP in bios to make a printer work on a "longer than standard" run. Very expensive shielded EPP cables can fix this too. Has to do with crosstalk and interference.
  

0x0000007B

• Apparently, you have a disk error -
  
  
  • run "hqtools" and check that the disk controller is appearing ok
    
  • Boot device is not accessible
    
  • Problem running defrag or scandisk
    
  • Virus problem possible if using MS Anti Virus type of program
    
  • Sometimes DOS utility can cause these
  
  

0x00000067 or 0x00000069

• This specifically indicates a bad disk controller -
  
  
  • Only fix possible is to remove disk controller (if add in card) and use eraser on contacts, and then reseat. Otherwise replace defective controller.
