Hi,

I installed a upper class filter driver to Disk Drives (GUID =
{4D36E967-E325-11CE-BFC1-08002BE10318}). Toaster filter driver
available in xpddk under src\general\toaster\filter\clasupper is used
for this purpose.

But when I reboot the machine, it will not boot agian execpt in "Last
Good Configuration".
Think that filter driver installation was not correct.
Installation Details are as follows.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\mydiskfilter]
"Type"=dword:00000001
"Start"=dword:00000000
"ErrorControl"=dword:00000001
"DisplayName"="mydiskfilter"
"ImagePath"= "Full SYS file path here"
"Group"="PnP Filter" ( Also tried "System Bus Extender")

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}]
"UpperFilters"= "PartMgr mydiskfilter"

Please point out what is going wrong here.

regards
John

What happens? Crash?

What is "Full SYS file path here"? You can't use "C:\...".

There may be a problem in your filter as well.

Try DDK\src\storage\filters\diskperf. It's a filter driver for a disk, not
for a toaster.

Always wear your safety glasses before playing with diskperf-

It does *nextIrpStack = *currentIrpStack instead of IoCopy....
It uses notification event (manual reset) to do synchronzation but never
clear it.

Solved now.
Reason : Driver name was not in 8.3 format
