PS2 problem

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

Does the KB work outside of windows? As for accessing the CMOS?

I had a similar problem happen to a machine where the 8042? controller chip
flaked out on the motherboard and my only solution was to use USB devices.
However, I understand this would not work if the server firmware does not
support legacy USB KB for out of band management.

hello lonnie,

to fix the problem you are facing, take the following steps: -

1 Verify that KBDClass.Sys, MouClass.Sys and i8042prt.sys files are present
on the system. if any of them are missing, copy them from a working sytem (
Same OS)

2 Browse through the registry to
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}:U
pperFilters

for the upper filters section ensure "kbdclass" is the only upper filter
listed. delete the addition upper filters.

also,

browse to
HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}:U
pperFilters

ensure the only upper filter listed here is mouclass. if not, delete the
additional filters.

if the above steps donot help, export the above mentioned keys from a
working system & import them to this server.

this should fix the problem. let me know if you need further clarifications
on this.

I am having a similar problem. I followed these steps, and yellow flag
went away,but the keyboard still does not work in Windows. The
keyboard still says that the drivers are not signed, altho each driver
says it is signed by MS

Neither PS2 or USB keyboard will work. PS2 mouse will freeze when
keyboard is touched. USB mouse works fine.

Any ideas?
