Running WinXP SP2 on Dimension 8250.  Recently I have been getting a lot of blue screen error messages, most of them related to rdbss.sys.    The message is not always identical.  Here is the text from the most recent:  "rdbss.sys   Driver system unloaded without cancelling pending operations.  Stop:  0X000000D4 (0XBAC97F38, DX00000002, 0X00000001, 0X804DBC9A).  rdbss.sys.  Beginning dump of physical memory.  Physical memory dump complete.  If problem continues, disable or remove any newly installed hardware or software.  Disable BIOS memory option such as caching or shadowing.  If you need to use safe mode to remove or disable components, restart your computer, press F8 to select advanced start options, then select Safe Mode."    

 

The rdbss.sys error message is the most common.  I have received a couple of others that I will pass on the fragments that I wrote down:  

 "IRQL_NOT_LESS_OR_EQUAL      0x000000a."  

 "0x00000D1 (0X01c5BBF4)  tcpip.sys.  Address B28A5014.  Base at B2867000.  Date stamp 4294CC20."

"Bad pool header  0X00000019."

 

As usual with Windows, I don't understand the error message.  I have corresponded with Microsoft, and they said my WinXP was a custom installation by Dell, so that Dell should be the ones with the answers.

 

If anyone has any ideas, please pass them along.  Let me know if I can provide further information.

Thanks
